@@shawnsatterlee6035 Tons of early 1900's tractors used gas/kerosene for fuels. Same idea, start on gas, warm up, switch to kerosene. I think they used a regular carb. Kerosene was much cheaper those days, so it makes sense to go through all that hassle.
On my 2 stroke moped on witch i modified the cyl and piston with books from the library, i found out the spark plug became red hot and would even run without the lead/cable plugged after pulling if off due to extreme high rpm and continue to run on the same rpm without sparks. i even used sun flower oil in the tank at some point and it smelled like restaurant.
I did the same thing on accident. I was running my minibike and ran out of gas so I started adding a little oil as the tank went down. Them I ran completely out of gas and so I started mixing acetone and oil. It was thin enough the carb could send it through but it was knonking and got so hot when I tried to turn it off it kept running. 😅

nitromethane is a power additive of 1% to 15% to an alcohol (ethanol,methanol) fuel ! wouldnt have thought nitromethane straight was any good as a fuel !
Astonishing that it ran at all. RC glow plug engines aren't compression ignition after all, he's quite wrong there. They got a very different kind of "glowplug", utilizing a hot filament that contains platinum or nowadays maybe some other highly catalytic metal. And that's how it ignites - not just due to heat, but because certain flammable substances undergo catalytic combustion/ignition when in contact with platinum - methanol reacting especially easy hence the choice as RC fuel. You could basically call it a catalytic ignition engine. There's even lighters working on this very principle, using a platinum wire/ball of platinum black catalyst to ignite methanol vapors. Yt sure has some videos on it.
@@xmysef4920 there is so much heat, spark, compression that technical they should run on just about anything with an octane rating. it just happens the nitro is the best for horse power. with such high combustion and temperatures the plug burns away like a welding rod. by the time they're three quarter track they are quite literally running like a diesel. purely by detonation.
Very interesting experiment and I'm not that surprised that an engine as simple and basic as the Lada will idle with glow plugs. But without any means of timing the ignition it's never going to run well at different RPM's. Still fun to see it running with the distributor cap off.

This might work if you lowered the voltage to the glow plugs. It would lower the temp of the plugs. This would have the effect of reducing the ignition timing
Yea, think of the hot tube engine, there the hot tube was only barely even heated dull red, not bright orange as combustion pressure would just blow it apart at that point, this was the exact issue early hot bulb engines had, until compression was increased toward early diesel engine levels where the holt bulb only needed to be heated to a dull red for starting.
@@jasonharrison25it might be harder to shunt the glow plugs because they have common ground on chassis and cylinder block. Better put a series high power rheostat to reduce current going into the glow plugs.
There is one idea i wish i can imply , its by using regular gasoline engine with running cold water vapor steam, like the one produced by ultrasounds in humidifier, when you run it inside the manifold, this will highly increase gas milage especially when you control the fuel mixture and run lean fuel mixture
true, proper atomisation produces a better burn. globules of fuel don't burn as nicely and escape as unburned gas, Recirc valves try to take care of that by re-feeding the exhaust in the engine to give the now-gas a chance to burn instead of just evaporate.
yes its called watermeth injection, oldsmobile ran their turbo car with that in the 60's, basicaly cheap windsheild washer fluid, you can run the engine very lean and the cyl temps will be as low as a very rich fuel mixture, it works with water only but the performance will decrease by alot, the other benefit is that the engine stay clean, very helpful for modern direct injected engines
I have an old Briggs and Stratton service manual that describes running the engine on kerosine by installing an optional injector pump. It still uses spark plugs , and no glow plugs, but the carb is deleted. I ran a Briggs engine on propane by running a tube from the propane torch into the fuel line and choking it all the way.The 1980 Mercedes owners manual describes mixing gasoline with diesel fuel in cold weather if no kerosine( number1 diesel ) is available. I forgot the percentage, but it was not much. I’d like to see a Lada with an injector pump running on diesel kerosine.Chevy V8’s were converted to diesels in the 80’s but they didn’t hold up too well.Maybe a spark plug / glow plug- injector pump/ carb combo would cover all the bases?Bahahahaha😆
I have just found out about hot bulb engines as well as hit and miss engines. The hot bulb engine is amazing in it’s own right. The hit and miss engines are pretty cool. I only saw the smaller ones running. I found a video of one powering an oil pump in Wyoming. Those one are crazy. Small ones sound quiet, but the one powering the oil pump was something else. It had a rumble bass note and had a massive muffler.
Wow. It goes against everything I've ever been taught. Conventional thinking says it should have detonated itself to death. I'm kinda floored it even started. You can progressively drill out the main and midrange jets. Make sure you go straight and don't wobble the bit at all. Best done on a drill press. Outstanding video.
you guys never fail to come up with something interesting maybe you could design a carb for the nitro. anyway its always a pleasure watching the videos that continue to be a blessing. kudos to you vlad and your crew.
This is likely pre igniting on each stroke, so the ignition timing effectively becomes the fuel timing, if you had EFI you could delay the injection window to close to TDC and it may run. (IMO). By running it very rich as you did with the choke you delayed the time for the fuel to fully combust as so much more was in the cylinder. That's how I see it.
If he had GDI* he could delay injection until time for combustion. Most EFI systems inject fuel at the throttle body, or the intake port on the intake manifold. No way to inject fuel after the intake valve closes.
@@Texassince1836 Yeah but you could retard the EFI's timing to the point its throwing fuel as close to the intake valve closing as possible, instead from start to finish
I think for Nitro-Methane you need a much, much bigger jet in the carb. A 3,5cc model engine uses 250ml of fuel in 10-15min easily. Now scale this up to the Lada engine. Great video though! Greetings from Germany, Simon

Back when you converted the gas engine to run on diesel, I would like to see if you could get one where it 2 cylinders on diesel and 2 cylinders on gas. Maybe set them up where the gas and diesel are both at TDC at the same time so the gas cylinders and diesel cylinders are balancing each other.
Thank you for doing this, proving a concept and validating me. Back in the day I asked the same thing about replacing spark plugs with glow plugs and running a gas engine on diesel.
Diesel mechanic here. It wouldn't work as compression wouldn't be high enough and fuel atomization wouldn't be fine enough. The glow plugs are only starting aids. Thry only run for about 15-30 seconds until cylinder Temps warm enough so the compressed air is hot enough to ignite the fuel. Diesel timing is all on when the fuel is injected. There is no ignition.
The volatile fuels probably would've worked better had the glow plugs been duty cycled to keep them from igniting before higher compression was reached, nearer to TDC.
You need a lot more fuel flow for the model engine fuel vs gas. Methanol has a catalyst reaction with platinum in the glow plug which keeps them hot without the battery once running. On the model engine, timing is somewhat controlled by the fuel mixture.
"A bit of back firing but nothing unusual." What a quote. Also I would try opening up the idle jet somehow for the nitro. More stable but less energy dense so A LOT more fuel is needed. Like flex fuel cars and how much less economical they are on E85 as to Gasoline.
With glow plugs your HAVE to richen the mixture, richen the mixture to adjust the timing event, then with Rc fuel u have to run richer yet! The jetting in the gasoline carb is WAY to small for that
WOW! AS A MECHANIC I'M SURPRISED IT RUNS THAT GOOD. OUR FRIENDS THE RUSSIANS ARE TIRELESS EXPERIMENTERS WHO FIND UNORTHODOX ANSWERS TO MANY PROBLEMS INCLUDING, BUT NOT LIMITED TO, ROCKET SCIENCE AND CHESS. WITH EFI THESE GUYS COULD SURELY PRODUCE A FLEX FUEL DIESEL IF GIVEN SOME TIME TO PERFECT IT. WHILE THE IDEA SEEMS STUPID, THEIR RESULTS ARE AMAZING. GREAT JOB GUYS!
Я австралиец, учу русский благодаря жене, мне нравится этот канал. по моему опыту с gliw olugs мы используем ту же концепцию с модельными нитродвигателями :)
when piston goes down it sucks partly cold air and a little gas smoke. but when piston goes up gas smoke gets denser which easier tuches hot glow plug so piston repeats its cyrcle and engine works on smaller rpms, but partly
I'd like to see you try running the engine on diesel after fully warming it up on gasoline, I think that will work much better. I have gotten 4 stroke small engines to run pretty well and make decent power while running on diesel without spark or glow plugs, but the engine must be hot for that to work.
@@StayMadNobodycares Yup, it's a Briggs and Stratton lawn mower engine. The spark plug was still in the engine, but disconnected once the engine was warmed up and switched over to diesel. The engine sounds smooth and normal under light loads similar to when it's running on gas, but it has obvious spark knock under heavy loads. I should make a video of that some day, it's really cool to see a gas engine running with the spark plug disconnected.
Not surprised. The old 1970’s cars would sometimes keep running after you turned them off. Sometimes with the key in hand I could put it in gear and drive slowly. No steering wheel lock. Floor it and the engine would turn off. Happened on very low octane gasoline.
Reminds me of this old lawmower I got from my neighbor - it was capable of both dieseling and running on after cutting ignition (head was caked in carbon), and two-stroking at low RPMs possibly from really weak valve springs.
Diesel needs heat to vaporize properly. If you pre heat the diesel it will vaporize through the carb better. Run a steel fuel line and wrap it around the exhaust manifold to pre heat the fuel. I have run a gas engine on vaporized gasoline, alcohol, diesel, and kerosene. It's all about getting in to the cylinders in a vaporized form at the proper time.
Ppl did that back in days to raise octane in gas with high compression gas motors. I have done it for fun in my daily driver years back. It will bite u in the ass if just keep throwing diesel/kerosene in the gas.
i just remeber ,the vw ap engine if you have oil on the fuel after the engine warm up you can remove the power from the spaks plugs cables and the engine still rum
Ultra high compression and the heat generated by it is what causes combustion of the air/fuel diesel mixture in a diesel engine. 'glow plugs' are only necessary as a catalyst to get the 'process' started momentarily, usually on cold days. Gasoline engines to not produce high enough compression to induce combustion of diesel fuel, they rely on a spark to ignite the lower compressed gasoline mixture to ignite. They do produce (barely) enough compression to ignite diesel fuel with the 'help' of continuous glow plug operation to provide the added heat necessary, as shown in this video.
As long as you aren’t running lean, this just works because the flame front won’t move forward willingly during the compression stroke, and doesn’t really make power until it squishes.
it's firing on the intake stroke. that's one reason why gasoline engines need variable timing. if they just spark all the time they will fire before the intake valve is closed, and what you have with glow plugs that are just like a spark plug firing all the time.
diesels will run without glow plugs, they're just needed to warm the cylinders on cold starts. Point being, the spark plugs will be the same as an engine without glow plugs, and it will still run fine.
It's a little thing called compression, which this doesn't have enough in first place. The induction is way wrong also. But compression is the biggest factor here foremost.
I WAS MIND BLOWN TOO!! How!!!!!! Incrívelmente incrível!!! Muito Legal o experimento! i'd never thought it would run that good, I thought it would predetonate as heck. But I guess that predetonation only happens when there is hot spots on the piston, not on the plug, thus when the mix is cimpressed the fuel hits the glow plug and kabooms!
It is most likely igniting way too early, but it's also pretty likely the mix never gets compressed enough before ignition for hot spots other than the glow plug to have any effect
If you could try scale model aircraft glow engine plugs and methanol as fuel, it could be interesting. The glow plugs have a platinum wire heating element which due to some catalytic effect remains hot after the engine is running and the electric current is disconnected.
Filipinos do this all the time, actually. Usually on things like farm trucks. Even a low compression engine can run diesel, albeit not very well. Generally diesels tend to inject fuel as the piston is moving up, and gasoline mixes fuel on the down stroke of the intake stroke. This is why you are getting the backfiring, and why it won't rev well. Also, diesel tends to burn slower than gasoline, which would explain the low rev, the cylinder isn't reaching max pressure at the right time. Running a slightly lean idle should fix the idle issues, I would think as the cylinders would stay hotter. I would say try moving the cam one tooth advanced (open the intake and exhaust earlier). It might close the intake early enough to build a little more compression, at the expense of airflow at high rpm. Diesel engines run by "excess air", meaning you rev them by adding air to the same amount of diesel. I think you need to lean it out quite a bit to get it to run normally.
I was playing with a two stroke weed Wacker years ago I heated the spark plug with a torch and put it in the fuel was a mix of vegetable oil used motor oil and a little either.it ran smoked allot and you had to hold the idle up to keep it running.
Needs more rotating mass put a auxillary big flywheel off harmonic balancer so it can rotate push thru on idle power heavier flywheel will help propel power....also moving the distributor to tighten or loosen when pistons compress will also need to be tried
Maybe the next project could be adding a glow-spark combo to see how well you could run an engine on a gasoline-diesel mixture. There could be a goldilocks sweet spot in the ratio (50/50, 60/40 gas to diesel, etc.)
ethanol, methanol and i'd guess alcohol use in the case of ethanol 30% more fuel to do the same job/workload. so one would assume nitro methanol would use some more as well. i think the reason the petrol was idling ok ish and poor revving is the heat is being blown out at higher rpms if you used hot exhaust to preheat an air intake like on some old school petrol/diesel engines that have grid heaters to start in cold weather i think it would work much better.
The biggest problem with trying diesel is the fact these Ladas have too low compression to properly ignite it. If I were to try though, I would start it on gas and switch to diesel while it's running. Starting on diesel and kerosene is hard, that's why for a long time farm equipment had two types of fuel, one for starting, then the other for cost effective operation.
I remember that some methanol-fueled engines used on model planes and UAV's can be converted to burn gasoline by adding a carb, a CDI and replacing the glow plug with a spark plug. So vice versa.
No ignition timing with constant glowing glow plugs, did they ever have a carbureted engine that ran on nitro fuel ? Keep up the great job, you make my brain hurt with ideas !
Put spark plugs back into it and run it from nitromethane alone. You will have to add a ton more nitro fuel though in a higher percentage than 16%. I watched a stock Chevy LS make close to 600 HP on the Dyno with a nitromethane methanol mix a few months ago
try to pair with the fuel injector conversion, then you can control the fuel better, and also try 24v glow plugs or to run the 12v ones on higher volts to keep them hot
I would of liked to see what would happen if you used that rc glow fuel with the spark ignition and the carburetor tuned to supply at least 30-35% more fuel than it did with gasoline depending on the percentage of nitromethane of the rifle glow fuel. I know when a four cycle compression ignition engine with a glow plug is converted to spark ignition the engine will produce between 40% to 75% more power depending on the percentage of nitro in the fuel, the cam profile and number of cylinders. when a .5-1hp 20cc four cycle gasoline weedeater engine is tuned to run just on methanol it'll make almost 3hp start adding nitro and it's not hard to get to 5 hp but at that point you need aftermarket piston aftermarket cam aftermarket head studs, head gasket and rod bolts and the head and deck should be machined to raise the compression if done right that 20cc engine will make the same power as your average lawnmower engine on gasoline. if you had tuned the carburetor for the methanol/nitro fuel blend I'm sure it would of worked OK but if you had used that fuel and the spark ignition that little engine would have made big power as long as the ARF was kept safe nitromethane adds more oxygen and makes more power than nitrous but has near 1 to 1 fuel ratio and methanol is 5 to 1 naturally aspirated so a lot more fuel is burned compared to gasoline`s 14.7 to 1 fuel ratio which means a lot more power
I watched you connect the wire straight from the battery. I didn't think it would excelerate without an induction system. Was there one in place? The induction system adds voltage to the plugs enough to ignite the mixture under loads. Maybe the metal in the glow plugs weren't conductive enough to carry the load without over heating.
My first guess is the engine runs like any other with low compression... and a gas engine in stock form will be about half of a diesel engine. Yes, it will run better if you richen the mix, but only to a point. BTW, even a diesel has timing advance, but it's in the fuel, not the ignition. You might be able to cobble up some fuel injection to fix some of this, but not the compression.
Use a squirt bottle of fuel to feed more into the carburetor as a test. Then try to drill bigger holes in the brass fuel jets (holes) inside the carburetor.
I used to make thick ass smoke screens with my old car. I routed washer fluid through the intake and put diesel in the washer fluid tank. Before you yell at me, it was a beater.
try a mixture ratio of fuels gasoline and diesel. also modify the carburetor so you have better fuel adjustment control. change valve timing if possible without valves hitting pistons.
The glow plugs in my Duramax only ignites for .3 seconds prior to ignition. The glow plugs don’t ignite the fuel. The glow plugs warm up the cylinder walls. Compression ignites the fuel.
Nitro methane is working with rc glow plugs because they are made from platinum. The main reason for nitro methane is to react with platinum and keep the plug glowing.. here you are not having so much benefit of using it as fuel because your glow plugs are not made from platinum.. your videos are so much entertaining.. thank you!!
If they say it works on two stroke engines, why don't you try this on your home made lada two stroke engine you built a while ago? Maybe it will actually run this time.
The timing is way advanced, gasoline ignites a lot faster than diesel does, so as soon as the gas gets into the cylinder and gets somewhat compressed it ignites, you’d almost have to use race fuel, like 110 octane gas and see if that helps the fuel ignite slower
I think that you should change the cam timing. It probably does not fire at the right time, because of the delayed ignition by not having an immediate spark.
I was thinking the same but reason being pre ignition as piston detonated down it draws fuel so its igniting it. Hope we get find out on this as I'm defo up for running me car on nitro like this 😂
I think the biggest problem is that the engine is misfiring too much. The fuel is detonating at the wrong time in the stroke. That is why the engine is shaking so bad. Compression engines use fuel injection timing rather than ignition timing on a combustion engine. With fuel injection timing, it sprays the fuel in at the precise moment to get the most efficient combustion. I bet if you find a more efficient way to deliver the fuel that your engine will run better. Also, a fuel injector will atomize the fuel vs just dumping it in the combustion chamber. Really good experiment though. I would have never thought to try that. lol
The thing is, glow plugs don't have timing. They're always on. Therefore you can't control the combustion like if you had with a distributor and sparkplugs. I am suprise it still "sort of" ran.

yes its called watermeth injection, oldsmobile ran their turbo car with that in the 60's, basicaly cheap windsheild washer fluid, you can run the engine very lean and the cyl temps will be as low as a very rich fuel mixture, it works with water only but the performance will decrease by alot, the other benefit is that the engine stay clean, very helpful for modern direct injected engines
Have you ever used a Direct injector outside of the engine, that is what it does, but with enough fuel quantity to actually make usable power
Injectors already atomize the fuel mixture. Probably could be improved though.
I have an old Briggs and Stratton service manual that describes running the engine on kerosine by installing an optional injector pump. It still uses spark plugs , and no glow plugs, but the carb is deleted. I ran a Briggs engine on propane by running a tube from the propane torch into the fuel line and choking it all the way.The 1980 Mercedes owners manual describes mixing gasoline with diesel fuel in cold weather if no kerosine( number1 diesel ) is available. I forgot the percentage, but it was not much. I’d like to see a Lada with an injector pump running on diesel kerosine.Chevy V8’s were converted to diesels in the 80’s but they didn’t hold up too well.Maybe a spark plug / glow plug- injector pump/ carb combo would cover all the bases?Bahahahaha😆
I have just found out about hot bulb engines as well as hit and miss engines. The hot bulb engine is amazing in it’s own right. The hit and miss engines are pretty cool. I only saw the smaller ones running. I found a video of one powering an oil pump in Wyoming. Those one are crazy. Small ones sound quiet, but the one powering the oil pump was something else. It had a rumble bass note and had a massive muffler.
Wow. It goes against everything I've ever been taught. Conventional thinking says it should have detonated itself to death. I'm kinda floored it even started. You can progressively drill out the main and midrange jets. Make sure you go straight and don't wobble the bit at all. Best done on a drill press. Outstanding video.
you guys never fail to come up with something interesting maybe you could design a carb for the nitro. anyway its always a pleasure watching the videos that continue to be a blessing. kudos to you vlad and your crew.
You guys should try and make a Dual overhead cam head and direct injection lada engine.
And call it a "Cosda" cosworth/lada haha
The injection timing could be adjusted to inject fuel at TDC preventing pre-ignition or detonation.
This is likely pre igniting on each stroke, so the ignition timing effectively becomes the fuel timing, if you had EFI you could delay the injection window to close to TDC and it may run. (IMO). By running it very rich as you did with the choke you delayed the time for the fuel to fully combust as so much more was in the cylinder. That's how I see it.
If he had GDI* he could delay injection until time for combustion.
Most EFI systems inject fuel at the throttle body, or the intake port on the intake manifold. No way to inject fuel after the intake valve closes.
@@Texassince1836 Yeah but you could retard the EFI's timing to the point its throwing fuel as close to the intake valve closing as possible, instead from start to finish
I think for Nitro-Methane you need a much, much bigger jet in the carb. A 3,5cc model engine uses 250ml of fuel in 10-15min easily. Now scale this up to the Lada engine. Great video though! Greetings from Germany, Simon

Back when you converted the gas engine to run on diesel, I would like to see if you could get one where it 2 cylinders on diesel and 2 cylinders on gas. Maybe set them up where the gas and diesel are both at TDC at the same time so the gas cylinders and diesel cylinders are balancing each other.
Thank you for doing this, proving a concept and validating me. Back in the day I asked the same thing about replacing spark plugs with glow plugs and running a gas engine on diesel.
I always wondered if this would work
@@TonytheGr8 So did I
Diesel mechanic here. It wouldn't work as compression wouldn't be high enough and fuel atomization wouldn't be fine enough. The glow plugs are only starting aids. Thry only run for about 15-30 seconds until cylinder Temps warm enough so the compressed air is hot enough to ignite the fuel. Diesel timing is all on when the fuel is injected. There is no ignition.
@@АлакПатрова Thanks for the in depth explanation. The last person I said that to insulted me and said I didn't understand anything!
The volatile fuels probably would've worked better had the glow plugs been duty cycled to keep them from igniting before higher compression was reached, nearer to TDC.
One day, this man is going to change the world.
You need a lot more fuel flow for the model engine fuel vs gas. Methanol has a catalyst reaction with platinum in the glow plug which keeps them hot without the battery once running. On the model engine, timing is somewhat controlled by the fuel mixture.
"A bit of back firing but nothing unusual."
What a quote.
Also I would try opening up the idle jet somehow for the nitro. More stable but less energy dense so A LOT more fuel is needed. Like flex fuel cars and how much less economical they are on E85 as to Gasoline.
Cool story bro
With glow plugs your HAVE to richen the mixture, richen the mixture to adjust the timing event, then with Rc fuel u have to run richer yet! The jetting in the gasoline carb is WAY to small for that
3:49 "How is the engine running"?! = LADA!!!
Try warming up a gasoline engine then change the fuel to diesel and test if it works, and if not mix diesel with gasoline with normal spark plugs*
Isn't that actually going backwards tho? Yeah ppl would add some diesel or kerosene to gas to jump up the octane, so basically that's same thing.
IT was warm when they added diesel
@@uooello13 with normal spark plugs*
@@shawnsatterlee6035diesel lowers octane rating though, it literally is meant to ignite soon as possible
It should be able to made to work just fine, used to be very common for tractors

OUR FRIENDS THE RUSSIANS ARE TIRELESS EXPERIMENTERS WHO FIND UNORTHODOX ANSWERS TO MANY PROBLEMS INCLUDING, BUT NOT LIMITED TO, ROCKET SCIENCE AND CHESS.

Я австралиец, учу русский благодаря жене, мне нравится этот канал. по моему опыту с gliw olugs мы используем ту же концепцию с модельными нитродвигателями :)
when piston goes down it sucks partly cold air and a little gas smoke. but when piston goes up gas smoke gets denser which easier tuches hot glow plug so piston repeats its cyrcle and engine works on smaller rpms, but partly
I'd like to see you try running the engine on diesel after fully warming it up on gasoline, I think that will work much better. I have gotten 4 stroke small engines to run pretty well and make decent power while running on diesel without spark or glow plugs, but the engine must be hot for that to work.
without spark or glow plugs?
@@StayMadNobodycares Yup, it's a Briggs and Stratton lawn mower engine. The spark plug was still in the engine, but disconnected once the engine was warmed up and switched over to diesel. The engine sounds smooth and normal under light loads similar to when it's running on gas, but it has obvious spark knock under heavy loads. I should make a video of that some day, it's really cool to see a gas engine running with the spark plug disconnected.
Not surprised. The old 1970’s cars would sometimes keep running after you turned them off. Sometimes with the key in hand I could put it in gear and drive slowly. No steering wheel lock. Floor it and the engine would turn off. Happened on very low octane gasoline.
Reminds me of this old lawmower I got from my neighbor - it was capable of both dieseling and running on after cutting ignition (head was caked in carbon), and two-stroking at low RPMs possibly from really weak valve springs.
Diesel needs heat to vaporize properly. If you pre heat the diesel it will vaporize through the carb better. Run a steel fuel line and wrap it around the exhaust manifold to pre heat the fuel.
I have run a gas engine on vaporized gasoline, alcohol, diesel, and kerosene. It's all about getting in to the cylinders in a vaporized form at the proper time.
Surprising the engine did run, and the glow plugs didn't melt, as they are not designed to be left on all the time. great experiment.
Hi try mixing the fuels a little of each type see if it will run with the benefits of each one added together.
Ppl did that back in days to raise octane in gas with high compression gas motors. I have done it for fun in my daily driver years back. It will bite u in the ass if just keep throwing diesel/kerosene in the gas.
Will it run?
Come on, this is Garage 54!
It will run, At Least Once!
If you drill a small recess in the exhaust valve it will fill with carbon and get hot which will produce a similar result
You mean like a makeshift pre-combustion chamber?
@@VitoVeccia just has to be about an 1/8" diameter and slightly deeper
@@Mrpurple75 that's a pretty neat trick.
This channel is great. I knew I was hooked when I saw you guys doing concrete tires lol
i just remeber ,the vw ap engine if you have oil on the fuel after the engine warm up you can remove the power from the spaks plugs cables and the engine still rum
Ultra high compression and the heat generated by it is what causes combustion of the air/fuel diesel mixture in a diesel engine. 'glow plugs' are only necessary as a catalyst to get the 'process' started momentarily, usually on cold days. Gasoline engines to not produce high enough compression to induce combustion of diesel fuel, they rely on a spark to ignite the lower compressed gasoline mixture to ignite. They do produce (barely) enough compression to ignite diesel fuel with the 'help' of continuous glow plug operation to provide the added heat necessary, as shown in this video.
As long as you aren’t running lean, this just works because the flame front won’t move forward willingly during the compression stroke, and doesn’t really make power until it squishes.
it's firing on the intake stroke.
that's one reason why gasoline engines need variable timing.
if they just spark all the time they will fire before the intake valve is closed, and what you have with glow plugs that are just like a spark plug firing all the time.
Maybe just can try with one diesel injector
From a bigger diesel like 6 litter engine
One of these days, they’re gonna stumble onto something incredible
They will discover torque converters finally
Guy try to see if you could do if the spark plus will make a diesel engine will run
diesels will run without glow plugs, they're just needed to warm the cylinders on cold starts. Point being, the spark plugs will be the same as an engine without glow plugs, and it will still run fine.
It's a little thing called compression, which this doesn't have enough in first place. The induction is way wrong also. But compression is the biggest factor here foremost.
I WAS MIND BLOWN TOO!! How!!!!!! Incrívelmente incrível!!! Muito Legal o experimento! i'd never thought it would run that good, I thought it would predetonate as heck. But I guess that predetonation only happens when there is hot spots on the piston, not on the plug, thus when the mix is cimpressed the fuel hits the glow plug and kabooms!
maybe if it had waaay more fuel it could work, or just mixing the 3 fuels together!/!
It is most likely igniting way too early, but it's also pretty likely the mix never gets compressed enough before ignition for hot spots other than the glow plug to have any effect
May sound dumb, but knowing these guys... Could be possible, hockey puck pistons. Think about it.
Hockey pucks cannot melt! This is a fantastic idea, but how will you make them pistons?
If you could try scale model aircraft glow engine plugs and methanol as fuel, it could be interesting. The glow plugs have a platinum wire heating element which due to some catalytic effect remains hot after the engine is running and the electric current is disconnected.
Very nice thats what i wanted! But now ad your Dieselpump Gas injection system you did some time ago...
Filipinos do this all the time, actually. Usually on things like farm trucks. Even a low compression engine can run diesel, albeit not very well. Generally diesels tend to inject fuel as the piston is moving up, and gasoline mixes fuel on the down stroke of the intake stroke. This is why you are getting the backfiring, and why it won't rev well. Also, diesel tends to burn slower than gasoline, which would explain the low rev, the cylinder isn't reaching max pressure at the right time. Running a slightly lean idle should fix the idle issues, I would think as the cylinders would stay hotter. I would say try moving the cam one tooth advanced (open the intake and exhaust earlier). It might close the intake early enough to build a little more compression, at the expense of airflow at high rpm. Diesel engines run by "excess air", meaning you rev them by adding air to the same amount of diesel. I think you need to lean it out quite a bit to get it to run normally.
I was playing with a two stroke weed Wacker years ago I heated the spark plug with a torch and put it in the fuel was a mix of vegetable oil used motor oil and a little either.it ran smoked allot and you had to hold the idle up to keep it running.
Gotta give credit to the starter motor 😂
Needs more rotating mass put a auxillary big flywheel off harmonic balancer so it can rotate push thru on idle power heavier flywheel will help propel power....also moving the distributor to tighten or loosen when pistons compress will also need to be tried
Maybe the next project could be adding a glow-spark combo to see how well you could run an engine on a gasoline-diesel mixture. There could be a goldilocks sweet spot in the ratio (50/50, 60/40 gas to diesel, etc.)
One of the best episodes so far. Brilliant!!
You could mix some benzene with diesel and try different ratios until it works
ethanol, methanol and i'd guess alcohol use in the case of ethanol 30% more fuel to do the same job/workload. so one would assume nitro methanol would use some more as well.
i think the reason the petrol was idling ok ish and poor revving is the heat is being blown out at higher rpms if you used hot exhaust to preheat an air intake like on some old school petrol/diesel engines that have grid heaters to start in cold weather i think it would work much better.
you always can change the valve size in the carburetor. In this way can add more fuel when not idling (because idle is can change with a screw)
Cool story bro
9:25 the bottom of the air filter housing is glowing red hot😮
For ethanol fuel you need to open the carburetor jets around 30% more and it will run. Don't give up on it!
I wonder if the main younger guy got caught up in the mobilization or fled? I haven't seen him in a long time.
The biggest problem with trying diesel is the fact these Ladas have too low compression to properly ignite it. If I were to try though, I would start it on gas and switch to diesel while it's running. Starting on diesel and kerosene is hard, that's why for a long time farm equipment had two types of fuel, one for starting, then the other for cost effective operation.
Man I love you guy’s content I watch like every night at this point you guys video is on top of my recommendation list every time I open RUclips
I remember that some methanol-fueled engines used on model planes and UAV's can be converted to burn gasoline by adding a carb, a CDI and replacing the glow plug with a spark plug. So vice versa.
No ignition timing with constant glowing glow plugs, did they ever have a carbureted engine that ran on nitro fuel ? Keep up the great job, you make my brain hurt with ideas !
Put spark plugs back into it and run it from nitromethane alone. You will have to add a ton more nitro fuel though in a higher percentage than 16%. I watched a stock Chevy LS make close to 600 HP on the Dyno with a nitromethane methanol mix a few months ago
I love the stuff you do on this channel.
Lada engine never ceases to amaze me,
Wish we had Lada cars in our country too,
you want to use like 4 head gaskets to lower compression then run diesel, turn timing back so it pre detonates, its a slower combustion, a lot slower
i want to see a part 2
try to pair with the fuel injector conversion, then you can control the fuel better, and also try 24v glow plugs or to run the 12v ones on higher volts to keep them hot
its just a matter of compression, shave the block and the head to up the compression to around 12 to 1 and it should run fine
With the rc fuel you need to increase the jetting size and tune the air fuel screws and idle, and i bet it would run way better
yes when you go from petroleum to alcohol you need to run much richer, much more fuel to air
I would of liked to see what would happen if you used that rc glow fuel with the spark ignition and the carburetor tuned to supply at least 30-35% more fuel than it did with gasoline depending on the percentage of nitromethane of the rifle glow fuel. I know when a four cycle compression ignition engine with a glow plug is converted to spark ignition the engine will produce between 40% to 75% more power depending on the percentage of nitro in the fuel, the cam profile and number of cylinders. when a .5-1hp 20cc four cycle gasoline weedeater engine is tuned to run just on methanol it'll make almost 3hp start adding nitro and it's not hard to get to 5 hp but at that point you need aftermarket piston aftermarket cam aftermarket head studs, head gasket and rod bolts and the head and deck should be machined to raise the compression if done right that 20cc engine will make the same power as your average lawnmower engine on gasoline. if you had tuned the carburetor for the methanol/nitro fuel blend I'm sure it would of worked OK but if you had used that fuel and the spark ignition that little engine would have made big power as long as the ARF was kept safe nitromethane adds more oxygen and makes more power than nitrous but has near 1 to 1 fuel ratio and methanol is 5 to 1 naturally aspirated so a lot more fuel is burned compared to gasoline`s 14.7 to 1 fuel ratio which means a lot more power
I watched you connect the wire straight from the battery. I didn't think it would excelerate without an induction system. Was there one in place?
The induction system adds voltage to the plugs enough to ignite the mixture under loads. Maybe the metal in the glow plugs weren't conductive enough to carry the load without over heating.
5:10 backfire is the detonation. Lol
My first guess is the engine runs like any other with low compression... and a gas engine in stock form will be about half of a diesel engine. Yes, it will run better if you richen the mix, but only to a point. BTW, even a diesel has timing advance, but it's in the fuel, not the ignition. You might be able to cobble up some fuel injection to fix some of this, but not the compression.
Use a squirt bottle of fuel to feed more into the carburetor as a test. Then try to drill bigger holes in the brass fuel jets (holes) inside the carburetor.
Early car's used a glow plug ignition system, using paraffin torch to heat the plugs
Tie chock half way carb will suck more gas but keep it from sucking less air
I used to make thick ass smoke screens with my old car. I routed washer fluid through the intake and put diesel in the washer fluid tank. Before you yell at me, it was a beater.
try a mixture ratio of fuels gasoline and diesel. also modify the carburetor so you have better fuel adjustment control. change valve timing if possible without valves hitting pistons.
just love how it sounds like a diesel but actually gasoline
The glow plugs in my Duramax only ignites for .3 seconds prior to ignition. The glow plugs don’t ignite the fuel. The glow plugs warm up the cylinder walls. Compression ignites the fuel.
Nitro methane is working with rc glow plugs because they are made from platinum. The main reason for nitro methane is to react with platinum and keep the plug glowing.. here you are not having so much benefit of using it as fuel because your glow plugs are not made from platinum.. your videos are so much entertaining.. thank you!!
highly underrated channel
I would suggest making the air jets smaller and increasing the fuel jet size
If they say it works on two stroke engines, why don't you try this on your home made lada two stroke engine you built a while ago? Maybe it will actually run this time.
The timing is way advanced, gasoline ignites a lot faster than diesel does, so as soon as the gas gets into the cylinder and gets somewhat compressed it ignites, you’d almost have to use race fuel, like 110 octane gas and see if that helps the fuel ignite slower
e85?
I think that you should change the cam timing. It probably does not fire at the right time, because of the delayed ignition by not having an immediate spark.
I was thinking the same but reason being pre ignition as piston detonated down it draws fuel so its igniting it. Hope we get find out on this as I'm defo up for running me car on nitro like this 😂
Made a diesel gasoline motor essentially.
That's not going to change anything
True! But what's worse is that there is NO spark timing, so it wont affect much, if anything at all
Need try it in fuel injection intake? 1 last thing you not done there was feather throttle at engine building revs doing adjustment 👍
Ooh also try the two-stroke motor with the hot bulb plugs and diesel
I think the biggest problem is that the engine is misfiring too much. The fuel is detonating at the wrong time in the stroke. That is why the engine is shaking so bad. Compression engines use fuel injection timing rather than ignition timing on a combustion engine. With fuel injection timing, it sprays the fuel in at the precise moment to get the most efficient combustion. I bet if you find a more efficient way to deliver the fuel that your engine will run better. Also, a fuel injector will atomize the fuel vs just dumping it in the combustion chamber. Really good experiment though. I would have never thought to try that. lol
Put the glow plug spark plugs in the two-stroke lada motor you built I wonder if it would run like the glow plug motors in RC cars
if it was injection then u could control the ignition, with glow plugs its igniting too early and since there is no timing now to adjust.
The thing is, glow plugs don't have timing. They're always on. Therefore you can't control the combustion like if you had with a distributor and sparkplugs. I am suprise it still "sort of" ran.
