Impressive that it even runs with the indirect injectors becoming direct injectors :D
that was what i thought aswell poor old indirect injectors trying to handle direct work... would maybe work better if they turned the pressure up on the IP. looks to be a bosch VE rotary pump, and can easily be adjusted to pump out much more diesel
@@Norwegian_Bastard This engine has a low compression ratio and low compression pressures in it's cylinders, the injectors don't have a hard job. They know what are highter pressures in a diesel engine. These low compression pressures make starting difficult, the engine runs on it's own only when the combustion chambers are hot.
Are they definitely indirect they may just have been in the manifold from when they ran a gas engine with diesel injection
@@henrys.6864false. Biggest one that come to mind, the old Ford 7.3 idi. Which as stated I it's own title indirect injection that said, on the IDI diesels, it's not sprayed thru the intake manifold like you would on a gas engine, but rather the injectors are injecting fuel into a precumbustion camber and not directly into the cylinder.
@@henrys.6864 No, before 1990s pretty much all diesels were indirect injection which spray the fuel into prechamber in the cylinder head, not directly to the cylinder as is now normal.
A heavy start and a lot of smoke indicate that the fuel is being burned at too low a temperature. Therefore, the engine ran better on a heat gun, because it probably increased the temperature of the air in the cylinders by 100°C, so the fuel could burn in more optimal conditions. Glow plugs would help start, but the smoke would still remain. To change this, you would have to raise the compression ratio even more to warm up the air even more, or reduce the combustion chamber, as the old diesels had the so-called pre-combustion chamber and indirect injection. As the engine warms up better after work, it will start normally and smoke less, but it will still not be as good as it should be. Currently, your engine is behaving like a heavily used diesel with damaged glow plugs, or a diesel engine running in good cold. Either way, the air temperature in the combustion chamber is too low, so the fuel is more likely to smoke than burn. You could call this engine more of a medium compression ratio than a high compression ratio. Engines such as can be found in e.g. tanks that smoke far too much, but can accept fuel of almost any quality.
Pre compressing with a turbo might suit the unfavourable geometric compression ratio
I thought maybe a leaner fuel ratio although I don't know diesel engines
@@off-gridoutbackaustralia The working principle of a diesel engine is to run on a lean fuel mixture. The amount of air is the same, only the amount of fuel varies. If the dose of fuel was too rich, then the engine would produce a lot of soot and the exhaust gases would be black. Basically, in diesel engines black exhaust is too rich a mixture, blue is oil burning and white is burning at too low temperature.
@@SW-qr8qe I think that here a compressor would be a better solution instead of a turbine, because it would top up the engine from the lowest speed and there would be no problem with turbo lag or driving with too low power demand. If you drive a diesel on the road, but you need too little power, the turbine will work very little, or it will not work at all, because the energy of the gases will be too low, even though the engine speed will be appropriate. In this case, the compressor would still pump the nominal pressure, even if you were driving downhill and braking with the engine, it would also maintain the pressure, which is unattainable for the turbine.
Yes this behaves like a heavily modified tractor pulling diesel engine, with 12-14 compression ratio. Runs horribly at idle and low power, and cannot start without starting fluid and/or heat gun, but runs ok at full load. When we compression test diesels we consider below 20 bar worn out and needing a rebuild. 26-28 bar is a good number
The whole process of you guys trying to get it running and the heat gun was pretty dang funny 😆
Nice job
the heat gun did the job that would normally be done with the glow plugs (especially in an indirect injection engine)
@@petelattimer6808 Yep. Pretty cool
They basically ran a (very low boost) super/pro charger, with no intercooler, through it. (We could just call it a glow plug, but I would argue there's a little bit of a boost there)
@@jwalster9412 I can guarantee you that a heat gun is not going to add any additional psi lol.. It was just warming up the intake temps which helps combustion
@@TTime685 Yup, I don't think it flows enough to fill a cylinder at idle let alone boost it (would more than likely choke it if adapted/sealed to the intake)...
I don’t think BMI Russian get enough love for translating the videos. I would just like to say thanks for translating all the videos.
This is awesome!! And I especially love Vlad's little chuckle of excitement at about the 6:01 mark, when the engine tries to fire up! 🤣
So it needs more air to start. Put some turbos on it it should idle better
@@blueice1141 Unless it's ridiculously small, a turbo isn't doing anything significant at idle. And it looked to me like the engine was getting all the air it needed. There was nothing on the intake, so it was wide open!
You guys are absolutely amazing ❤👍 gas powered run on diesel and still sound like a gasoline engine brilliant
I believe that's the cam timing that keeps it sounding petrol. Same as the diesel engine still sounded diesel, even when ran on petrol.
I accidentally put 5 gal of diesel in my empty tank from a can.
My 81 ford f100 with an inline 6 smoked a bit but otherwise ran fine until I tried to turn it off and nothing happened. I had to choke out the air intake to get it to stop.
Haha! Interesting. Something that wouldn't happen on a fuel injected car.
I did the same thing to my riding mower, I didn't realize it until it wouldn't start the next day and I smelled diesely gas when I drained the carb.
This mower has a fuel cut solenoid, I wonder if it would have kept running if it was nice and hot and I killed spark with more diesel in the tank...
You experienced good ol' fashioned "dieseling." That's when there's so much carbon crap in the combustion chamber that it will continue to ignite any incoming air/fuel mixture. Modern computer controls and other developments have eliminated that problem.
To make it start better you need to raise compression ratio by milling some metal off of the underside of the cylinder head, so the combustion chamber gets smaller.
In the last video they did that about as much as they could unfortunately
The first video I've watched from you guys in a while it's good to see you guys build cool stuff like this and not fizzle off like some other channels stick to it guys
I would really love to see this fully completed, would be super interesting :)
Here’s one thought I have:
The engine is right now set up as direct injection, however I believe the injectors you used are from an indirect injection engine. These injectors might not work very well for direct injection. Perhaps if you used injectors specifically for direct injection the results might be better!
Wait, isn't every diesel direct injection? Or were those gasoline injectors?
@@skuula No, some have a prechamber.
@@skuula no because why do we call the ford 7.3 IDI an IDI indirect injection
@@skuula No, older diesels inject into a pre-chamber. Modern diesels inject directly into the cylinders and have pistons with a cup in them to aid in mixing and combustion, older style diesels had this cup inside the head. Diesel would be injected into this chamber before reaching the cylinder. If you look at their diesel to gasoline conversion, you can see these chambers when they have the head off.
I can’t imagine injectors intended for pre-chamber injection to work well for direct injection. Since that significantly affects the mixing of the diesel and air mixture and the combustion timing, that might cause the engine to not run well. It might never run well with this setup.
Modern diesel engines also don’t have such high compression ratios anymore, some having as low as 16:1. Compression ratio is not the issue in this case, I think it’s mostly because they used an incorrect type of injector. The pistons not having the cup in the center either might also cause issues. While pre-chamber injected diesels can have flat-top pistons, direct injected diesels commonly have pistons with a cup in them.
All of this together might result in poor mixing of the diesel and the air. Though the Garage54 crew is EXTREMELY skilled and experienced with gasoline engines, they might have some things to learn about diesel engines!
@@skuula nope older diesels were indirect injection where the fuel was injected into a pre combustion chamber in the head, reasons for indirect injection is that they run a lot smoother, quieter, can rev higher and have a wider power band making them ideal for use in cars
It works but it seems the compression is still a bit low, as it doesn't reach high revolutions when throttling it, you can also notice it smokes alot, the combustion chamber also isn't very efficient for diesel fuel application... Still great effort! A vw diesel fuel pump from a golf mk2 might have been a better option as it is belt driven instead of chain as it doesn't need lubrication, great video! I love watching your stuff!
I love the ingenuity of these builds, driven by curiosity and fun, always great to watch
Now all that's left is to fit it into a Lada.
You really need a compound turbo set up on there!!! That would def bring it to life!!!
Please do a high power engine for cheap next time!!!! Big fan, long live the channel!!!!!!
Highest All Motor lada engine
its way cheaper to put 2 lada engines together than modifying an engine to produce high power
Fantastic, I've been waiting to see something like this since you running gas in a diesel.
Love how real these guys are
In about 1985 , We had an old Wisconson engine that we ran for many hours on Diesel . The Only changes we made were a valve to shift from the gas tank to the diesel tank . the only problem we had was to Remember to shift back to gas before we shut it down. Also there were several Tractors built that were Started on gas and shifted to diesel or Kerosine to be Cheaper to operate . Thank You
Might be the most practical video ever from you guys! Love it
People have already talked about the injectors being meant for prechambers being the reason for difficult start. I think more advance would really help as well. But if you already haven't thought of it, you could adjust the injector pop pressure to be higher. My old 240 used shims in the injector, and I'm sure those injectors are similar. It would mean less fuel flow and less power, but it should get much better atomization.
main reason is the lack of glow plugs to preheat for initial cold start. at those compression levels, they WILL need glow plugs for initial start up. which is why it worked better with the heat gun on it.
@@petelattimer6808 This was gonna be my point... I had a glow plug fail in my car once and that sucker wouldn't fire on all four until it got some heat in the block... Sucker ran like crap for a solid minute lmao
I don't know why they didn't just run a single injector through the intake. It would have been way simpler than boring and taping the whole head and setting up 4 injectors.
Because diesel is a timed injection so that won't work
@@petelattimer6808 Would a block heater be enough to keep the combustion chambers warm enough for a cold start?
Heat grid in the intake and a roots supercharger to blow through the non crossflow head would be cool and probably help it a lot
Yes. That's exactly what I was thinking too.
perfect id bet shed clean up too
The pistons should have some coned shape spikes on top of them for more easy start and running i think .
That's a very interesting experiment.
I really learned some stuff with this, especially when I saw the heat gun, because I didn't thought about increasing the intake temperature, despite remembering that some diesel engines do have an air heater at the intake to allow cold temperature operation. Also, I do wonder about what if it had glow plugs. Great video.
Someone here commented that glow plugs may help but it's still an overall lack of combustion causing white smoke.
Sooooo awesome. That engine is gonna be packing I think once a nice drivetrain is connected.
In the 50's, Eduardo Barreiros in Spain transformed the Soviet 3HC gasoline engines to diesel, it was cheaper than buying a diesel vehicle in postwar times. He built a business empire thanks to this genius of the time.
If you bring the compression down to ~5:1 and use the exhaust to heat a carburetor it will work quite well and run efficiently, but require gasoline for initial starting
I'm assuming the pump and injectors are not for direct injection. And the camshaft is for gas. But you still got it to run! Wow
I can run a coal train on waffles.
@Garage 54 You should make this engine into a project. Now find a truck to put it in and see how much load it can haul around, then turbo it, try to haul again, and then increase the boost and try again.
Maor!!!
This is fantastic, well done!
Next step: Teak it. Install it in a Lada and drive.
👍👍
The pure pressure difference is absolutely insane. Those things are definitely solid running stock
Says no views, but 13 likes! RUclips is corrupt to the core! I respect 54's content and crew!
Sounds legit:
You need to watch 25 seconds to make a “view”
I personally hit like as soon as i open the video if it’s Garage 54 😀
It says over 900 views for me
Welk, I know here in chinada the leftards believe all Russian's are bad now because of the propaganda.....errr......I mean news outlets like cbc
I still hate their 'dislike' change
Yep. RUclips is reallly bad. Sadly it has no other to match it...
Add a grid heater to intake. It's easier than trying to figure out glow plugs.
amazing work honestly, no one is really bothering to do these things. its even better how you keep things simple as well
It's begging for a turbo!!
It will also run better due to the higher compression and heat of the incoming air
Would love to see how it holds up to the stress!
def would love to see how well this performs towing/hauling or even on a dyno !!😉
Damn this is awsome. Should have some nice torque.
This is fascinating. My dad tried to convert a Moskvich 2140 engine to diesel using a custom gasket head, but the compression destroyed the crank shaft.
That’s awesome. I would’ve thought the higher compression would be too much for the engine and separate the head. One way I usually get old engines running is put gas in a bottle with one hose going down into the fuel and the other pulling the fumes into the engine and run it through the intake. Slightly dangerous when it backfires though 😂. This has got to be the best video so far. 👏🏻👏🏻👍🏻
This is so awesome! Reminds me of what Chevy did with some of their first diesels. I think you guys need some sort of forced air,be it a turbo or supercharger,with the higher compression and it being diesel its likely not getting enough fresh air in and making it doggy. Love your videos!!! 👌🏾👌🏾👍🏾👍🏾🤘🏾🤘🏾🏁🏁
I'm excited to see what you do with this engine!
I was thinking you wouldn't have enough compression even after upgrading the original pistons and/or stroke -- and would end up needing glow plugs. Good job! I'd love to see this installed in a car and driven around.
Others have mentioned the injector issues but the piston geometry probably isn't helping things either. Diesel engines typically use a cone and cup in the center of the piston with the fuel injector directly above the cone tip. The tip of the cone helps the injector spray spread out and mix fully with the air in the piston, as well as provides a sharp point that can heat up quicker for better ignition.
Not only is this engine using a flat top gasoline-style piston, but the injectors are at the oblique angle of the spark plug. Most of the injector spray is probably hitting the wall of the chamber and not actually spreading out into the air, so it's ignition rate is really poor. Upping the pressure might help a bit with atomization but it's only going to do so much.
Also for starting looks like you'll need a little 12v intake air preheater!
This. That's why all the smoke and sputtering.
I was sure you were going to be able to do this because years ago GMC and Detroit Diesel took a gasoline engine that was in a pickup truck and converted it to diesel. They sold pickup trucks with this engine. They had quite a few problems with it nevertheless. Anyway you did a very nice job and it worked.
Cars too. A lot of them. Hence, the "Lemon Laws" were enacted after that debacle.
If you're talking about the Oldsmobile, which had nothing to do with DD, it only shared the head bolts with the gasoline engine
@@MiG21aholic It was GM's idea, and they tried to introduce a Isuzu 6 into the Chevy light sedan line, but the Olds, debacle carried over into the rest of the GM lines.
@@Nighthawke70 yes. But they did get DD involved to produce the 6.2 after that
hold on a minute Detroit diesel had nothing to do with the GM diesel fiasco , GM converted the olds 350 (5.7 L ) to diesel people talk about the block but the problem wasn't the block it was the weak internals like broken crankshafts bad head gaskets and so on i had an olds cutlass wagon 5.7 diesel i fixed it many times i'm a mechanic when it ran it was great and good MPG but always breaking down i replaced injection pumps , GM made cars wagons and trucks powered by this engine and I tell you more you probably don't know that they built v6 3.8 diesels , now fast forward a couple years Detroit Diesel designed and built the 6.2l diesel a very different engine and later the 6.5 L i own one , but nothing beats my past 3 Mercedes diesels and even 6 VW's i love diesel cars
If it's struggling without the heatgun you may need to fit some forced induction to raise the dynamic compression ratio.
It is useless, cold turbocharged engine cold starts as naturally aspirated since the turbo acts more like restriction other than booster. I would recomend some heating grid on intake manifold, similar to that heat gun
@@Matej_Strba or like glow plugs
@@Danielagostinho21 it's a lot of machining. They can mount this heating grid on top of intake manifold.
or machine taller pistons
@@Matej_Strba It's a direct injection engine, if it won't fire right up the cr is too low.
"The starter motor is fed up with us at this point" I'm dying :D
My Dad used too convert gasoline tractors to run on diesel. In the late 1950s and 1960s in Mexico. Gasoline was expensive and hard to come by diesel was plentiful and cheap. You would have to start them on gasoline. Once warm switch to diesel. Still used carburetor and spark plugs and stock compression.
then how does he do it?
@@rookieman329 make adaptor under carburetor so exhaust runs under it. So it can heat and automize fuel (diesel turn to vapor) before going into combustion chamber. This allows the spark plugs to ignite it.
I wanna know what the drug joke was
Me too
These Russians have absolutely nothing to do with Ukraine
Post 2014 Ukraine was a creation of CIA and Mossad. It was created to be a festering cancer right on Russia's doorstep and Putin finally did what had to be done.
We are in there fighting to keep the cancer alive and continuing with the plan that Israel demanded from us in the beginning.
The old Khazar kingdom occupied part of where Ukraine is right now and Israel wants it back. Their whole genesis will lay bare the giant lies they've rammed down our throats for centuries. The whole "Holy Land" and "Chosen" fables have no basis in reality and the State of Israel is in danger of being pushed into the Med by a new Muslim uprising that uses Hezbollah and the Palestinians as the tip of the spear.
But they have a lot to do with ladas
I mean they do though by their lack of any pushback. It’s like saying the German people had nothing to do with the holocaust as they watched people being rounded up around them and did nothing to stop it…..just sayin
@@jgaines3200It’s really not the same. Also, I don’t think a channel about cars should be expected to talk about their stance on geopolitical conflicts / wars… Majority of people click for the car stuff, not for their takes on irrelevant (to this channel) things
Although they could probably make a tank's engine by welding old Lada parts together
Oldsmobile did that in 1978 and it didn't last very long. There best one was the V6 Diesel because I Drove one after rebuilding the transmission! That car would fly!!! I LOVE THIS CHANNEL!!
i worked on a 3.8 v6 diesel it's extremely rare
we use to have an outboardmoter 5HP that starts on gasoline and after 5 minutes switch to diesel and run on diesel with sparkplugs and carburethor. no injectors needed, cant remember air or watercooled. but was 2 stroke 2 cilinder engine.
great work you do.
I was wondering if you had considered mounting two starter motors, just to make life a bit easier for the motor(s) to turn the engine? A coolant preheater might also be useful in situations where there's no Cyril with his industrial hair drier, as might a manifold preheater. Glow plugs in the cylinders would be a definite bonus, especially in cold weather.
Just for the hell of it, how about making a "hot bulb" version of the engine?
The indirect injection aka pre-chamber diesel engine is a direct descendant of the hot bulb engine.
@@BlackPill-pu4vi Quite, and by default, hot bulb engines had a lower compression ratio, which makes this engine a potential candidate to operate in that fashion.
Two starter motors are almost impossible to sincronize
@@mrsnezbit2219 no its possible
@@mrsnezbit2219 Not at all!
You are so creative! Lots of inspiration I get from you.❤
Wow that was fun.
Aaah nothing better than given some ether to a diesel engine to help it start.
Wow, lada motors really can do anything. It's impressive that it survived being a diesel engine.
Мне нравится видео ❤️
Compression ratio imo. It's not that high to ignite diesel by compression that's how diesel engine works 🤔. Great stuff as always thanks 54 👍
Huh?
You need to have a pre catalyst (maybe cerium oxide matrix) to remove the nitrogen in the atmosphere before it's enters the manifold! Thanks for sharing
Amazing work guys!
If you can drill some holes one the chamber for glow plugs and get a grid heater and figure out injection timing it would be a solid unit
Should have just went to Propane...
Edit: So what timing did you get to? 10' Advanced? 15'?
I've also found that coolant heaters and silicone pad oil pan heaters help massively. They get it closer to running temperature to take out the warm up factor (where you have to REALLY advance the timing. Bonus points if you insulate it so only the engine sucks in the heat.
Glow plugs and a turbo would probably make it run better well in the fun and functional way. Keep up the fun
The heat gun shows us why pickups have glow plugs, grid heaters and block heaters. It makes them warmer and happier
Run the exhaust through a turbo and back into the intake mixing the air from the other side of the turbo at the same time. 🙂 If you need any help contact me.
I like the heat gun idea that was cool.
Definitely needs a turbo to ram some air down its throat. haha
Awesome video, at first I had doubts. But you actually made it work, Awesome work
You guys never cease to amaze me, GM made 2 gas engine's into diesel also. But they both are unreliable and underpowered. Can't wait to see this one running in a vehicle.
Thier abilities are impressive, many years of knowledge in that shop!!
Great job guys 👏👏👏👏 really enjoyd this 😊
Awesome work as usual! The way it runs, it acts like it needs a turbo. It's not atomizing the fuel and that's what gives the white smoke.
Turbo isnt responsible for the atomization, and it wouldnt help at all on idle. Static, and dynamic compression ratio is the key thing. Also theres still something wrong with the timing
this guy does the things no one dares to try respect
Eez good Rrrahh-shin diesel! Well done boys! Major pucker factor with all the spinning gears just itching to grab a loose sleeve not to mention copious amounts of ether and choking smoke. Perfect!
I wish you can try to heat up diesel oil around 40°C to 50°C or try different temperatures where it will do continuous combustion just like normal operation in a gasoline engine. Because in ships, we have diesel oil which do not need heating to feed on engines, sometimes we actually have coolers to slightly increase the viscosity. And we have bunker fuel which is a thick fuel that we heat before feeding on engines. Just wondering if heating diesel oil just before the flash point will perform regularly on a gasoline engine.
More power to your channel, you are making our imaginations into reality.
All we need is a turbo, and then it'll really sound like a diesel!!!!
I know people has done diesel conversions in the past, especially with old Volvo Redblock engines. Like Lada engines, they are built like tanks, and are easily able to run with the higher compression rates required for diesel. You won't get that much power out of it, but the fuel consumption goes down by a lot.
Now, most diesels today are turbocharged, to allow for much greater torque and power output compared to naturally aspirated diesels.
Very interesting and it looks like great fun. By the way, using the heat gun is a great idea that I might try on my Fordson Dexta tractors, instead of using EasyStart.
This is a great experiment.. Well done guys...
Like the different ideas you guys come up with for experiment's 👍
10:04 w Polsce tak odpalało się autobusy z wysłużonym silnikiem diesla 😁 mówiliśmy o tej metodzie "dać mu poczytać gazetkę" tylko przy użyciu palnika do papy
Najważniejsze że działało XD
My old shop teacher said this was impossible, Garage54 proving shop teachers wrong AGAIN!
Fellas, please get a good powerful FAN in that room, > For YOUR SAKE!~
Yeah , turning diesel fuel into noise and smoke like GM Detroit power units. Most season'd folks will remember the Olds diesel via GM too. My father (old diesel mechanic) actually bought a Chev truck with the Olds diesel in it... thanks for yur video !
2:37😂.
Thats about how my welds look😊
Awesome work!
I would love to see this get running properly. I have often though about the possibility of converting a large displacement ( relatively) petrol engine to a low power diesel. I would want it for driving a generator and 30 HP would be heaps.
I figure that the forces with higher compression at low power outputs would not be above the stresses of the engine doing it's original 150 HP or whatever therefore should last a decent time.
Late comment I know, but the channel was blocked for 2 years in my country. Been binging for a while. Still great content and unlimited ingenuity and ideas. 2👍's up. PS: I ran an unmodified 1.9 ltr Renault petrol engine on kerosene 20 years ago. The downside, it only ran on hot summer days and at 3500 rpm's. 😂.. fun days at the track. 😉
I know I’m a year late boys, but Cummins 6bt motors used to come with a grid heater in the intake manifold to preheat the air for easy starting. I’m sure one could be adapted
My two stroke weed eater refused to start with petrol, so for the fun I put diesel in, and it started straight away, it was smoking a lot, but it started with diesel, where it is actually a petrol two stroke engine
A lot of commenters going on about heat/glow plugs. It's a direct injection engine, it shouldn't need pre heat.
The cr is too low to get the heat into the air.
Either the combustion chamber shape is wrong or the cam timing isn't trapping the air.
Well c'mon...we need the translated heat gun reference. lol
These videos are great, gets my mind going
With all that white smoke I would suggest that it's either as under sized injectors for what you just built or the injection pump is weak or you don't have enough compression
You might be able to make the injection pump spit more fuel out and that might work too.
In the early days of Ag tractors, there were carbureted spark ignition engines that ran on diesel fuel. They had two tanks, one for gasoline and one for diesel. They would have gasoline engine compression. You would start them on gasoline through its' jet, then once it was warmed up good you would switch to diesel through its' jet. The spark plug fired both. Once warm enough of the diesel would vaporize to give you ignition and the heat would vaporize the rest of the diesel to burn and you could shut off the gasoline.
army trucks also
Love it. I wanted to experiment with something similar, but high compression and gasoline at very lean ratios… what Mazda does basically
Lada engineers going: "Ivan, why you no think of this before, blin?"
In the 80’s Oldsmobile had a diesel that was a converter 350 gas engine
When I worked in power generation, I had to travel a lot. I had to have a laptop to run quantifications and the desktop CPU Origin laptops saved me hours of time while I slept so I could go back on site in the morning.
Why while you not around in the 80s when Canada had Ladas. I would have love to have try this in my Niva! That Lada engine is tough, my timing chain jumped and I drove it over 100kms with valves hitting the pistons. Great engine
1:43 this bit has the same engagement as the bit where the engine starts
Alot of manufacturers made diesel engines from gasoline Chevrolet being one of them with the 6.2 where the block is all gasoline but heads, pistons etc where strengthen for diesel use
The engine came to be somewhat reliable under certain conditions and they later put a turbo which made 6.5 we had both at one time very loud the back two cylinders would have the tendency to heat up on towing so kits where offered to provide extra cooling from thermostat housing to the rear back two cylinders nissan did it two with the maxima (American market) in the 80s with diesel engine that started as a gasoline in-line 6 ended up being very reliable and quiet
