most mechanics: it doesn't work... why?
these guys: it works... why?
Also applies to programmers!
Fuckin 💀 🤣
Me too. I'm blown away you can just bolt a diesel pump on a petrol and make it multipoint mechanical fuel injection 🤯
Guys you forgot Alfa Romeo ,vw, Mercedes use mechanic fuel pump in the 70s. Is nothing new, but apply diesel pump in the Lada was awesome.
Good job garage 54

Guys....That pump has an LDA or boost compensator, if you add a turbo, and boost reference line to the LDA, it will automatically add extra fuel in proportion to boost... if you tune the pump right for the correct AFR, that is .. with using the max fuel screw and adjusting the spring pressure in the LDA.. would actually be pretty clever stuff.
It'd also produce some real good power for an inline 4 lada engine.
I think that would work and produce some big power👍.
Also would be nice to see the engine run on diesel and gasoline at once, just hook the single injector back up and put some diesel in the tank
@@veoverse4286 I'd be curious if it would run on atomized diesel or kero , ignited like a petrol engine with a spark... atomized diesel burns good in open air so.. Could work?

You should do these mods to your inline 6 lada engine.
That engine kindof reminded me of a 2jz lmao

@@jd7896 it probably has a similar displacement to.
Edit: as mentioned at 25:45 this is a Lada 1.5L . Not sure what the Displacement of I4s used for the I6 was, but I assume it's probably a 1.5-1.6L if you know please share.
therefore, I can conclude that it the I6 Lada has probably a smaller Displacement than the 2JZ, around 2.25L - 2.40L. I wonder how much power that engine could make with a turbo.

I'd bet that mechanical port injection with that velocity stack would generally run well even without the extra pressure. Also that long intake really helps with low end torque, which is why you're getting so much pep and throttle response.
Really cool work guys.
Also, I bet that single intake it chocking the engine.
they used the same intake with the DIY electronic fuel injection and it was slower... Diesel engine fuel pumps run at extremely high pressures compared to gas pumps. Higher pressures give much much better atomization and creates a much better fuel mixture
@@dieselgeezer18 finally someone gets it!
They should make the intake longer, like Holley SkyRam long XD
Small correction: That's *_not_* a Velocity Stack.
What they have is closer to a Tunnel Ram.
A velocity stack is a cone inlet mounted *before* the throttle plate (butterfly), but most importantly, at the opening of the cone is an airfoil shape. It's that airfoil that causes air to actually _accelerate_ into the opening and down the throat of the cone; hence "velocity".
Almost like ram-air -- on an airplane, not the cold-air mounted on the hood that we called ram air in the muscle era -- but at a standstill, since it does with without the use of a headwind.
_BONUS FACT: Cooling towers, those big ""smoke stacks"" of a nuclear power plant (used on any steam power facility, coal before nuclear), is actually an upside-down Velocity Stack. The whole cooling tower is not sitting flush against the ground, but is raised up. As the hot air rises, it draws in cool air through the bottom, then rushes up and out the smaller top opening._
Aside from that, you're totally correct on everything else!
I love listening to you guys. The translator knows perfect English grammar and has excellent skills, beautiful, thank you!
Back in the 80’s in Brazil they used to convert the old chevrolet inline 6 261 engines from the old petrol chevrolet trucks to diesel.
The conversion was made using the cylinder head from the Mercedes diesel OM 321. They used to use an adaptor plate to be able to bolt the cylinder head from the mercedes into the chevrolet block, then I’m not sure about the injector pump but it’s not hard to gear it onto the crank pulleys or using the distributor shaft as a source of 1/2 crank rotation speed. I believe they would adapt the diesel pistons onto the chevrolet rods, never got details about this conversion but spoke to people who done it themselves (My father). The engine would work quite good but wouldn’t last long because of the lack of support for the crankshaft (5 main bearings only).
the misto quente was horrible, it didn't run like a real diesel engine and the consume of diesel was almost equivalent to the gas engine... and as you said, the engine wouldn't last not just because of 5 bearings, but due to the lack of resistance of material of piston rods, bearings, etc. a diesel engine requires a highly resistant engine due to the high compression from diesel.
Yep, they took the 4.5 I6, "canavieiro", and stuck a Mercedez head and rods, didn't work so well, but it works any way, they rather make a Detroit Diesel swap.
Rapaz que tanto de brasileiro falando bonito kkkkkk Ainda espalhando pro mundo a história do misto quente...
General Motors did something similar with the standard 350 V8 block. Converted it to a diesel. It wasn’t very good, but it did get decent mileage. They also did this with a 4.3L V6 but they used a heavier block. Those blocks were used in race cars converted back to gas because they would withstand the higher compression 😂
@@weaponizedautism6199 they do this with the nissan rd28 and convert it to gas still today. Stronger blocks on diesels like you say. They use it as a stroker block too compare to the nissan rb26 found in the gtr's
The two stroke oil should work wonders. My concern was first how the pump wouldn't get lube but the oil should do a better job than our modern diesel fuel which doesn't do pumps any good at all.
Some people actually put 2-stroke oil into their diesel fuel when they fill up for that precise reason, modern ULSD fuels are not that great for older pumps and valvetrains, as the sulphur in the older fuel was acting as a lubricant, once that's gone entirely, older diesel engines will need to use additives to not blow up...
@@twocvbloke I do with my 12v. When I had my VE pump I still did. I put break in oil and two stroke oil in my diesel when priming and breaking in my p7100
@@twocvbloke so the low sulfur diesel is good for emission regulations but wear out the diesel pump faster. Cant win.
@@midlifeparty Seems that way. I think I'll have to do the 2-stroke oil diesel treatment for my old Triton. Don't want her mechanical injector pump to start leaking and wear out until the engine hits near 1 million kilometers.
Emission systems can’t handle high sulfur fuel. All bad
it's like a mechanical injection system that was used on some race cars some decades ago.
the fuel delivery depends just on the revs. it's like a bosch system from 1955
both volvo and mercedes also used mechanical injection as late as the 70s early 80s i believe, it gave the volvo's more power than carbied or efi then but was less echonomical
missing one major thing, the amount of fuel delivered in each pulse is based on manifold vacuum on those old systems
@@Stale_Mahoney the Kugelfischer injection from the 60's used rpm, throttle,pressure, temperature to control injection, all done mechanically with shaped cams
@@fuzzy1dk good to see someone mention the ol' Kugel here !
they used rpm and throttle position, or for the turbo version throttle positiona nd boost press.
whats funny about these is that if you "unroll" the cam shape about its axis, you got yourself a 3d fuel map just like on a Alpha-n strategy on a modern ECU.
Top fuel and top alcohol drag cars are still using the same basic idea. Not sophisticated but still the best way to dump huge amounts of fuel into the chsmbers
So they basically made a mechanically injected lada, sweet😍🙌🏼 (it’s ready for a turbo😈😆)
yeah it's basically same as boschs system on a mercedes, high pressure included.
which makes me think.. did.. did bosch do just exactly this in the 50's?
@@lasskinn474 my 79 450SL had that exact Bosch J-series mechanical injection
Yep, they did, GM also did with another name, the only problem was that require maintenance that ppl by that time didn't have the knowledge or thought it was too expensive to do, so they promptly replace it with a carb, years later Bosch made a monopoint electronic injector, which was simpler and easier to fix, the rest is history.
I was just thinking they basicly just build the bosch CIS Jet tronics used on a lot of European cars in the late 80s and early 90s
Yeah I think it would be most interesting if you guys would have your own dyno stand to test all those experiments. Keep up the work!
They have a homemade dyno made from an old treadmill you jog on
@@staceymcdermott4954 lol
Make one from an upside down Lada! ;)
you've managed to recreate the latest Petrol fuel systems! thats cool!
Newer engines nowadays have somekind of high pressure pump just like a diesel, to up the pressure a lot in the fuel rail. ive seen pressures above 150bar already. This is to atomize the fuel better, so the air really mixes with the petrol. gives a cleaner, more efficient and powerful burn.
just maybe you've started a retrofit trend! nice
except the new petrol fuel systems inject in the cylinder, with much more timing variation and complex duration control afforded by common rail computer controlled injection. I agree, though, for a hobbyist, this makes soooooo much more sense than going to a complete standalone ecu. You could mount one of these to your gasoline crate engine and it nearly run itself like a diesel, for what it's worth.
sugestion: try and make an opposed piston engine with two lada blocks head to head...
With the diesel injection pump!
@@NN1Ckl. How about three blocks and make it a Deltic. :-)
@@davidelliott5843 that's a bit harder... lol
@@davidelliott5843 That sounds WILDDDDD, you think they could get the geometry and weld 3 con rod tops to one conrod bottom and the crank? Do that with each set of pistons perhaps

Up!
You should totally kit this out and take it to a track, be interesting to see how well it drives there.
They should try building an actual racing lada and make a series out of it! Imagine a fuel injected 2L forced induction Lada!
Early injected gas Mercedes engines like the gullwing had this setup essentially. Gullwings were direct injection but the later 220se and similar cars were port injection but still using a timed high pressure Bosch injection pump.
Brilliant video guys I wonder how it would drive with a turbo from a diesel
i was just thinking the same thing same set-up but just add a turbo lol
Makes me wonder how much power this engine makes before it comes apart though.
You'd need to add a booster valve for extra fuel or else things would melt quick I'd say haha
@@aaronhall7740 it has that built into the pump already.. that ufo looking bit on the top of the pump adds more fuel when on boost..

@@khalidmohsen9599 fecal matter extrusion
This was an amazing video experience to watch. I never would have though a high pressure diesel fuel pump would have worked. Thanks for sharing.
It really isn't any different from normal port fuel injection, just using a mechanical pump and valves instead of their modern electronic counterparts. Modern high-efficiency gasoline engines use high-pressure direct injection too.
@@teardowndan5364 oh. I did not know. Thanks for telling me. I appreciate it. Thanks Again.
I've never heard Sergey rev a lada motor that high before lol 😂 that was awesome
There is a built-in governor in the diesel pump, makes sense that it ramps up fueling with the revs.
this was exactly how 80s mercedes fuel injection on their 6 and 8 cylinder usdm cars worked, they used a sort of "scale" as a throttlebody, mounted on the top of the pump. The farther down that plunger moved due to vaccum, the longer duration the mechanical injectors would spray. Very simple physics in hindsight, as our boy Vlad here showed us he got a hand for doing literally with his fingers!!!
Maybe with a vacuum solenoid connected behind the throttle body you can control the injection pump to get close to the right fuel air ratio
On the old gasoline MFI systems in 60’s Mercedes they actually have a small oil line from the crankcase that delivers a very small amount of oil to the pistons within the MFI pump. It is subsequently burned in the engine. This was one of the reasons MFI for gasoline never took off after the emissions regulations of the 70’s kicked in.
It would be interesting to run it with a wideband sensor to see if it's going rich and lean at different RPMs and loads. I mean really it has to be if the injection pump throttle is not being changed.
And add a stepper motor servo on the mixture control to run closed loop from a microcontroller, just for good measure?
Are you guys in the right channel? Sensors? We don't use this here. lol
Thats not a throttle as such. Its an enrichment device. It decides how much fuel you get per revolution so presuming the car needs a certain % of fuel at a given rpm and that doesn't change (it wouldn't on a petrol since stoic is always the same) then if its right at one rpm it will be right all the way up - or very, very close depending on how the thermal efficeincy changes based on air speed and volume.
I think it's all about the speed and timing. By getting the correct amount of fuel into the cylinder almost instantly after the compression stroke, the fuel has more time to mix with oxygen in the down stroke it creates a vacuum and force mixes the oxidizer and fuel even more thoroughly it's like a secondary atomizer similar to experiments when water boils at room temperature under a vacuum the gasoline is locked in place and evaporating.
@@SF-dy6hn The mixture control on the pump controls the cam timing which opens the valves to the injectors inside the pump. A longer opening angle on the cam means the injector will be open for longer, and more fuel per stroke, hence a richer mixture.
This is the sort of thing I’ve always wanted to do to see if it worked in theory.
Garage54 does all the amazing stuff my mind conjures up. This shows high pressure port injection works. No need for complicated direct injection! Direct injection pressure, emissions cleanliness, and efficiency without expensive annoyingly complex fuel injectors that break. Pay attention car manufacturers, you guys over complicate everything! Garage 54 is on to something! Amazing work again.
yeah, it does work just that it's not optimized for it that's all
mercedes did this in the 80s before they decided to go to common rail efi like the rest of the world, they already milked this idea for its worth. Sorry to ruin your idea, the germans had it a long time ago
I’ll assume you’re referring to the 300 series diesel OM617’s. Those cars are amazing and my childhood favorites. My folks owned a few of em.
@@jamesadams2333 no, gasoline engines, look up k jetronic and how it works.
It’s amazing to see them upload great content.
Mechanical fuel injection Garage 54 style. Great stuff. Getting rid of the stock restrictive carb is always a win.
I've recently swapped my 12v from a VE pump to a P7100. I wish it was this simple lol. I clicked this video very fast because I'm interested on how it will work out. Love this channel
Awesome! At diesel fuel pressures, (1800 to 2000 psi), the gas is instantly turned to a fog that mixes perfectly with all the air it can get. Put the electric turbo on it and hang on.
I can see this with a turbo making 10 psi a lot of fun and not too hard to do and figure out the throttle cables. But that’s amazing work science
Fit an automatic Oiling system for the fuel to it, so you dont have to mix Oil into the Gas seperatly
and fit a trumpet onto the Trottlebody so the air can be sucked in way faster
Really enjoying this episode. Big kids playing with automobiles. Love it all. Keep it up!😎
As a former LADA owner and professional engineer.. I’m pretty intrigued by this channel.. Had an old LADA for 7 years I kept running while I was a poor student.. But I can’t decide wether this is a LADA tune shop, or a LADA torture chamber😀
Perhaps try upgrading it with tensioner, better pump mount, and try tuning it with an AFR probe to modulate the pump and throttle body optimally together (with the gas pedal cable, as it's likely running nicely because the fuel get's sprayed super fine, which likely mitigates a bit the effects of it running really rich or lean - as a matter of fact new gasoline turbo engines with direct injection use this high pressure injection effect exactly for the same reason).
Great experiment, the engine doesn't sound at all like a lada. Almost like a smooth R4 bmw engine.
To make a whole thing work properly, just add a starter motor powered supercharger you made a couple of videos ago, with a regulator to regulate an air amount.
Starter motors don't have enough power to make boost. Just blowing air is not enough, you need positive pressure in the manifold to make more power
@@Rudy97 then use a some kind of nozzle, for example convergent-divergent nozzle.
@@cenreaper3221 you can't make pressure without enough force to make the pressure.
@@MiG21aholic 😁❤️
@@MiG21aholic you want to say that turbocharger on normal cars have more power than starter motor?
`remember , a diesel engine has no throttle plate , the intake is always open in a diesel manifold , and the engine speed is controlled by the pump . The pump delivers the diesel directly to the cylinder at the very last minute as diesel combusts under pressure and not by spark , therefore the diesel cannot be introduced at say 30 deg btdc like in a petrol engine since it will prematurely combust or not comb at all so the diesel is sprayed at the very last point btdc and has to be at higher pressure than tat of inside the cylinder at that time wich is extremely high for diesel engines , so , the setup on your lada now works fine yes , but the mixture will never be correct . I bet you it over enriching it allot. Im glad you guys did this coz its something i have been wondering over for years and never had the chance to try . i knew it would work though...
The concept was used in many cars. Its called mechanical fuel injection. Vw Golf Gti mk1 = Kjetronic injection . Ford also had a mechanical injection. audi 5 cyl... im just curious to know how long the pump will last having petrol through it ....
You guys should put an O2 sensor to monitor the mixtures and connect throttle plate cable to the pump and move the two simultaneously.
I'd love to see what these guys could do with a 2.3 Ford Lima engine with the 8 plug head!
That would be nice but those are probably very rare in Russia
@@florin26balalau very true. I know the engine was used worldwide, but I'm not sure how easy they would be to come across outside of the North and South American continents. I honestly don't think these guys would even care to look for one. If I had the skill and abilities they use, as long as I had parts of an engine to start with, it wouldn't matter if it was just a box of random mixed parts, there would be a running engine at the end. 🙂
@@jasonkuehl639 this definitely was a good experiment that's for sure
It will be great to see the afr at certain rpms. Measure it with wideband gauge.
Now you can place a Turbo on the engine and adjust the fuel with the Diesel pump. This system is like the first mechanical injection. Good job my friend !!!!!
I love how responsive the engine is and how hard you can rev a Lada engine. Did all kinds of shit with my Niva and the engine held on until the body was rusted useless...

You have improved a Lada 👏👏👏👏
LADA might be the toughest engines on earth. They really run on anything, Soviet engineering at its peak.
man, every time i am thinking i will just watch a quick 5 or 10 minute video, you guys get me. I love you guys
I'm certain the atomization of the fuel from the port injection and diesel injectors is much better than a stock carbureted lada engine, letting the engine make more power and be more efficient
Definitely much more torque 💨 Enjoyed this video guys 👍
Of course it runs well, the high injection pressure and the fine nozzles make for great atomization.
I'm always so interested in the translation. Is "crapping out" really a Russian phrase too?!
Edit: Lol the voice he gave the guy in the street was pretty funny too.
It would be nice to see you try this on a course or street with no snow or ice do comparative drag race test
I love your channel! You guys are nuts with all of your experiments!
I have an idea for you.
How about taking an unfortunate Lada 4 cylinder, using stock size pistons, overbore each cylinder 0.010", 0.020", 0.030" and 0.040" respectively to see how much piston slap and excess clearance it can handle?
Maybe use individual header pipes to see how much each cylinder behaves with blow-by and how much compression loss occurs?
Either use stock size rings or oversized rings in the respective cylinders but each with a stock size piston.
Give it a try! Thanks and I look forward to seeing the results!
The last thing any engine wants to hear is, "Hey there fellows! Today we are going to abuse this here Lada four banger!"
Greetings from an American fan. I am living and working in Saudi Arabia as an aircraft maintenance technician.
super cool guys.... you should try a diesel turbo on the Lada .... that would be wild to see it hit boost and the pump would keep enuf fuel for it ..... rad guys peace n love stay safe n build on
Put her on the dyno. Would be curious to see the power band and hp compared to the stock configuration.
It would be very interesting to test it on a dyno and compare it with an unmodified engine to see how much extra you gain.
Those springs to hold the pump look great.
Now it needs a turbo, maybe add the electric turbo too and get a six cylinder pump for the six cylinder engine.
Connect the linkage between pump and butterfly. Leave the long intake, it should help with low rpm torque. Great work guys!!
Since the pump setting never changes, the air/fuel ratio depends on the throttle position. So be careful, the more you open the throttle, the leaner it gets.
the pump goes up on revs with the engine(and does more revs, pumps more gas injection cycles). the problem is more of the opposite, that driving part throttle at high revs gets you same fuel as full throttle (provided that the full throttle behavior is okay).
Yep, they need to hook up a wideband o2 sensor in the exhaust. That way they should be able to watch and correct the mixture.
The higher the revs the more line pressure. The lower the revs the less pressure. And with what we see in the video being the engine able to rev up top and still have the power to pull is a sign of enough (or more than that) fuel to create the power and is not going that lean (too lean and you start bogging down...not enough fuel to make good enough combustion)
True, it is running well and revs up and makes good power, so perhaps it’s not as bad as I thought. But at a minimum, the mixture is uncontrolled. Would be interesting to see the readings in real time.
@@facusan2339 they'd need to devise some more mechanical control like kugelfischer injection had, which is another similar thing to this what they built.
without having some more valves or bypass(back to tank) that operate somehow from vacuum, throttle position or such it's basically just a linear this many revs gets you this much fuel regardless of anything else going on. the bypass back to tank might be easier than having a valve before the injector.
I'm not sure how the ww2 era airplane injection worked, but there was some.
Now all that is left is to convert a gas Lada engine into a diesel. Put the injectors in the spark plug holes, put a bunch of weld into the combustion chambers to up the compression, and go!
they did a diesel to gasoline toyota
@@lasskinn474 I know, hence why I said go gas to diesel.

The Injection pumps I work on automatically trim the fuel based on engine speed using a governor. When you adjust the lever on the injection pump, you are telling the governor how fast the engine should be spinning and it increases/decreases fuel to hold that speed.
Awesome experiment guys, thanks for sharing.
I'm just glad this channel can still exist.
I was like 'a pump's? But I can see it's a whole intake injection control module that is mechanical & includes a high pressure pump, great engineering I learned something.
That runs super well!
This just shows once again that a Lada engine will run on what you give it......I Love Lada......from Canada
Our burnout cars have a pump similar to this, we run them on methanol and can adjust how much fuel goes into it to run it richer or leaner with a lever
22:33 That lada Nova wants to go out so badly
I'm not surprised this works fine. Mechanical multipoint fuel injection has been the method for supplying fuel to airplane engines for very long. Simple, reliable, and powerful.
glad they did the 2 cycle oil trick. That's a good one! will clean diesel inectors too
A wideband sensor would go a long way to show more results but likley hood is its really rich to start and comes alive as wakes up.
Great video :)
Some ford escorts in the 80s toyed with mechanical pumps, they worked fairly well but was overly complicated by the time injection was needed for emission and started to faulter with emissions
freaking cool I would never thought somebody would do this one day
This is awesome! Please put a wideband O2 sensor on this and try to tune it. Somehow fit a linkage to both the throttle body and the pump.
I mean the diesel combusts when there is enough compression so the timing will always be advanced and there for backfiring and working against the pistons.
If you can utilize sparkplug holes like making a tube that connects the injector it could be perfectly tunable besides the valve timings.
Of course it will never be perfect, but still straight injection.
As that engine stands now, pump timing really wont matter, because it is the intake air that desides when the fuel goes in.
Very nice job! One of your best.
A little bit of helpful information, there should be a screw you can adjust on the side of that high pressure diesel pump that will allow you to change the duration length of the fuel pulses for each injector also the golden ratio should be according to the math I've ran between throttle plate and fuel pump should be 3:1 the 3 being the air and the 1 being fuel. So in layman's terms if you crack the throttle all of the way on the intake you should only open the diesel pump throttle by 1/3 of its movement. The stoic mixture for fuel to combust is quite a wide and varied range, the only difference being there's a very small window of hyper efficiency where the fuel is completely burnt or there is no detonation occurring from running to lean or pig rich to wash out the plugs fire. I recommend finding a BMX bicycle brake cable a Teflon coated one to run from the fuel pump to where the throttle body cable is and run them parallel and have them pulled at that 3:1 ratio by using different sized cambered circle guides to regulate pull distance. Not sure if you know this or not but in the early 40s there were a couple cars that experimented from the factory with high pressure mechanical fuel pumps, also in most race applications with cars that run on methanol they have a mechanical high pressure fuel pump that is very similar to a diesel mechanical high pressure fuel pump.
this reminds me of the subaru ea82 engine. a tiny carb, to single port injection, to multi port.. all one engine. I then lived it again with gmc trucks. Cool show. injection is a champ.
This has to be my favorite episode of crazy things they done
So reversing the throttle setup to where the pump is adjust to your door pedal and your air intake is wide open will make that car extremely efficient.
I gotta say this channel is incredibly innovative.
8:26 lol the startup sound is exactly like old diesel bus😅
You need to link throttle and fuel pump together so that it gets more air when it gets more fuel.
I really like this one. I would like to see someone do some further testing with it. Like real world fuel economy and power numbers on a dyno. Before any changes then after.
This works much better than my old Hilborn racing system. They use constant flow injectors but vary pressure (much lower than this) with rpm and throttle opening. It's almost impossible to run on the street due to poor mixture control. I was TOTALY surprised to see it run this good!! I expected a lot of swearing just to get it to start and then even more when trying to drive it! When you are opening the throttle blade, you are leaning it out. (All racing MFI systems have a "barrel" valve hooked to the throttle to control mixture with throttle position.) When you open the Diesel throttle, you SHOULD be flooding it. I have built a lot of multi carb race motors, and boy, you can spend a lot of time messing with jets, etc especially daily driving it. Even going from your warm shop to the cold outside would make a big difference to a carburetor. That's why racers, especially with MFI setups, carry thermometers, barometers, and humidity gauges to calculate air density to jet properly day to day or day to night, its that finiky especially on gasoline. Alchohol is much more forgiving. But not this setup! It just EATS! it has to be that the fuel is vaporized rather than atomized. You could connect a simple choke cable to the Diesel pump to play with leaning it out while cruising just to see your mpg. A vacuum advance from a distributor hooked up to the Diesel throttle with a spring with different holes to hook it in and limiter screws to change fuel rate would make it more responsive Resist the idea of using an AFR sensor to tune it. But one to monitor it would be fine to record what IT wants. I bet you will find that sucker is running fine all over the place on AFR due to the vaporized fuel. I know from racing and dynoing engines that some like it lean, and some liked to smoke a little for max performance and not to be tuned to someone's perfect AFR numbers. Im intrigued!
Also, mount the pump to the engine, or you will fracture the high pressure lines eventually. Switch to a cog belt drive. You will probably find that the Diesel pump has its own internal governor that will shut down your fuel at a certain RPM. The biggest thing is to not lean it out so much that you hole a piston under load. Most Diesel injection pumps DO NOT change pressure to the nozzles with throttle changes, they change how long injection lasts and they advance or retard the timing also. Some Cummins engines with the PT (pressure/time) system did vary pressure as well. Good luck! Great show!
I love channels like this, where it's just a case of how do you control with fuel injection with an angle grinder and zip tie. No laptops in sight :)
Bravo - Serious skills!
now hack a diesel pump to use as a paint sprayer, or water jet for cutting things.
8th earliest for me!
Love the crazy builds!
That looks well good fun driving that
New amazing things to know now , woah this works better than i expected
Most older diesel engines with injection pumps don't use a throttle butterfly. It is normally a straight pipe. The diesel injection pump adds fuel to rev engine and take fuel away to decrease engine revs
That is awesome. Thanks for posting and showing us how you did it! ;)
