most mechanics: it doesn't work... why? these guys: it works... why?

You guys really need to invest in a dyno eventually for testing power levels with your crazy contraptions🤔

Time for some fine tuning Proceeds to bring a zip tie

"It runs, but I don't know how". This should be the motto of Garage 54!

You should do these mods to your inline 6 lada engine.

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.

6,5k rpm and his hand that close to a flapping double cam chain. That’s pure bravery!! I used to be a car mechanic but doing trucks and busses for quite some time now, well this is the ultimate combination of these 2 jobs.. Keep it up guys great stuff!!!!

So they basically made a mechanically injected lada, sweet😍🙌🏼 (it’s ready for a turbo😈😆)

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.

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).

I love listening to you guys. The translator knows perfect English grammar and has excellent skills, beautiful, thank you!

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.

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!

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

sugestion: try and make an opposed piston engine with two lada blocks head to head...

You should totally kit this out and take it to a track, be interesting to see how well it drives there.

Make a project car, where you take the best experiments and put them all together in one car. This experiment should be one of the things you add to it.

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

There is a built-in governor in the diesel pump, makes sense that it ramps up fueling with the revs.

Brilliant video guys I wonder how it would drive with a turbo from a diesel

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.

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

LADA might be the toughest engines on earth. They really run on anything, Soviet engineering at its peak.

I've never heard Sergey rev a lada motor that high before lol 😂 that was awesome

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.

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.

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!!!

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.

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.

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.

Fuel injected gasoline engined Mercedes in the 60's had inline "diesel" injector pumps to feed the motor. I had one, a 1966 W112 inline 6.

22:33 That lada Nova wants to go out so badly

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

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.

You guys should put an O2 sensor to monitor the mixtures and connect throttle plate cable to the pump and move the two simultaneously.

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😀

I'd love to see what these guys could do with a 2.3 Ford Lima engine with the 8 plug head!

It’s amazing to see them upload great content.

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

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

Make two stroke lada engine!!!

Vlad doesn't get near the recognition he deserves for teaching these kids! 🏆

I just want you guys to know how much me has an American appreciate your channel. It is great fun to watch you guys make up some totally bizarre car ideas. As a regular American I have absolutely no issue with the Russian people. I have long collected Soviet watches, and Soviet space history. Yuri Gagarin was one of my boyhood heroes. But I must ask that you please talk to you government and ask them do not use any kind of nuclear weapons. This would end the planet for all of us. So if you'd be so kind would you please petition your government to not use the nuclear option. I don't know if you can do this safely. But if you can we need to solve this as a people. The US, Russia, China, India, Australia, and Europe must work together to save our planet. Especially so we can have fun stuff like your videos to be enjoyed by all. Thank you and keep up the great work!

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.

Mechanical fuel injection Garage 54 style. Great stuff. Getting rid of the stock restrictive carb is always a win.

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.

now hack a diesel pump to use as a paint sprayer, or water jet for cutting things.

When I seen that the video was 28 min long, I thought you were going to have a pump timing issue. Good job!!!

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

Put her on the dyno. Would be curious to see the power band and hp compared to the stock configuration.

Those springs to hold the pump look great.

Really enjoying this episode. Big kids playing with automobiles. Love it all. Keep it up!😎

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.

It will be great to see the afr at certain rpms. Measure it with wideband gauge.

An actual success! You have improved a Lada 👏👏👏👏

Since no one has mentioned this, I will enlighten everyone. Diesels have no throttle plate, as a gasoline engine does. Diesel engine speed and power output are determined solely by the volume of fuel delivered by the injection pump. A gasoline engine's speed is regulated by airflow, making the throttle plate a key part. Essentially what has been done here is creating two throttle linkages, one for fuel volume, the other for air flow. Hence, they must be synchronized, much like a multi carburetor setup.

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'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

8:26 lol the startup sound is exactly like old diesel bus😅

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.

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.

I want to see this thing on the dyno compared to a bone stock engine.

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

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...

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!

FIT A STANDARD TRANSMISSION TO THE BACK OF AN AUTOMATIC!!

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!!

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 !!!!!

glad they did the 2 cycle oil trick. That's a good one! will clean diesel inectors too

Of course it runs well, the high injection pressure and the fine nozzles make for great atomization.

Definitely much more torque 💨 Enjoyed this video guys 👍

You need to link throttle and fuel pump together so that it gets more air when it gets more fuel.

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 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!

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.

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.

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.

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

I'm just glad this channel can still exist.

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 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.

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

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.

In addition to my comments below, I need to add that you just happened to get the right style of governor in your pump, (limiting speed) . There are two types of governor, limiting speed and variable speed or throttling governor. Variable speed should actually be called constant speed because when you move the control it adjusts the governed rpms not the fuel rate like yours does. So, like for tractors etc that want to hold a constant rpm as set by the operator even when going downhill or pulling hard the constant speed governor varies the fuel rate to hold the rpms at the selected point. If you had a constant speed governor as soon as the rpms came up unless you also moved the pump throttle up it would cut the fuel off. If the rpms dropped below that setting it would flood the engine trying to pick up speed to match the throttle rpm setting as if it was in the Diesel engine. However, limiting speed governors DO vary the fuel rate with load but only at idle (that's why the Lada started so easy, the pump automatically dumps in full fuel until idle speed is reached) or when "floored" at that point they will adjust the fuel rate according to load to hold maximum rpms but nowhere else in between. That's one reason why the old 2 stroke Detroits earned a reputation for being gutless in trucks. Unlike Cat or Cummins that had constant speed governors (think cruise control) For highway use. On road Detroits only had limiting speed governors (stamped with an LS on the tag)and wouldn't automatically react to going up a hill etc unless the pedal was on the floor and they were wound out. In dozers, tractors, scrapers etc they had variable (constant) speed governors (stamped VS) and because of being two stroke they responded quicker to a load than a turbochaged 4 stroke and did so with about 1/2 the cubic inches. So, in short most tractor pumps won't work and some on road pumps either. Hope this helps. I certainly would like to see this refined!

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 :)

Awesome experiment guys, thanks for sharing.

That looks well good fun driving that

freaking cool I would never thought somebody would do this one day

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 :)

It works really well ... 2oL\100km fuel consumption...

I would so set a servo controller on an arm and connect it to the throttle body to open and close the pump accordingly with a large servo, it would even it out even more and the air fuel mix could be tuned perfectly. Atomization with diesel injectors help as well. I am wondering if the pump is also getting a boost since you don't see diesels revving that high.

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.

Bravo - Serious skills!

This has to be my favorite episode of crazy things they done

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.

Very nice job! One of your best.

This just shows once again that a Lada engine will run on what you give it......I Love Lada......from Canada

Great shows guys Kudos to the editors and VO Look up a cross ram hemi or 426 cross ram to see the best tourque intake manifold ever made. Notice how intake tubes dip down to exhaust and is 3 feet long. That curve matters a lot for tourque. Tunnel ram manifolds are for RPM and horsepower.? They had a problem from exhaust manifold boiling gas in float bowls and creating vapor lock. Check those old Chyslers. Diesel injectors are under much higher compression pressures. I always thought it squirts variable by electric servo and CPU but at 7k rpm that would be insane valving. So it must use the piston pressure to open. Maybe its a electro mechanical trigger each intake stroke when it senses vacume That would allow the engine to always fire at right time. Then again maybe its just pooling the gas as if your squirting from a bottle. Set that rig up on a bench so we can see it squirt under prssure and SLOW MOTION cam on your phone. Internet came to late for us old timers Anyway just saying Try alcohol with that injector? Also did you ever hear of a reed valve? Or a circular flat valve? Its like a one way flap valve Great shows
