We make a 1-stroke engine (all pistons move in one tact) 

Hahaha!!

HAHA!!!

The smoothest one was the diesel version! Huehueheue

lmao

Lol

Yes!!!!

Customer states : Engine vibrating too much!! 😂

That would be hilarious 🤣

Omg. Yes! Do this!

This is a fantastic idea.

🤣

still smoother than a subaru

@@lostonlongisland6845nah

It's perfect Engine 4 the Vibratory-Rollers !!! 😀

watched this video and literally thought the same thing lol

@@MrHARDtaHANDLE1 everytime a new video drops from them ai think the same thing

Yeah, totally same. Love to see how it would work when its actually done

I can honestly say I have never thought about doing an engine this way.

😮

yes! this makes a lot of sense

This is the most likely explanation.

Not just the carb, the whole intake was only designed to feed one cylinder at a time. Same with the exhaust manifold and pipe, only designed to expel one cylinder at a time.

This, loose the exhaust manifold do four straight pipes, and the same with the intake with a carb for each cylinder. Also adding another clutch plate to the front to act as a fly wheel, this would smooth it out and lower the idle rpm.

@@jason86768 more tru also the exhaust and intake . can it push all the air out from all 4 same time or do ½-2/3 stay ?

@Auto Burn they could do it

Well. . . . If it ain't broke. . . Don't fix it

They could modify it to run on steam also, does'nt mean that they should

Using origional gas tank for water storage, back seat would hold the boiler. . . And just think how warm the driver would be no need for a heater!!!

@@jeremymaas8464 they already did that some time ago

Even if they are lawnmower carbs like the smal one it will surly be cheapest and u will get millions of views

im not shure but if u even add weigth to fly wheel it would help? Inline 4 engin has ligth fly wheel because it's pretty balance

Yes the carburetor is for 1 cylinder volume - not 4 ... !!!

and make it 2 stroke and skip the vaules, the carb was spitn thats lost power

It has a carburetor per piston

it's alive this monster is alive run for it

Imagine building it to withstand that rpm you are talking about and then building the car and transmission around the engine. So it’s always constantly at that engine rpm but you control the speed with a clutch and gears hahahhaa

The exhaust would have the same issue

Same with the exhaust

Thanks for saving me have to explain this

Yeah, that engine is starving for air and fuel.

@@honkhonkler7732 then why is it spitting out gas?

"kilLLLLL MEEEeeee!"

@@skylined5534 Hahahaha

Those are russians

I'm getting a headache watching the poor thing.... I can't imagine being in the car.

I laughed an uncomfortable amount at this

Ive seen already a wisconsin engine that had two pistons popping up and down simultaneously, never seen it run but i know it existed. I should add too that it had different timing for each cylinder, so they didnt fire simultaneously, the pistons just moved simultaneously

Parallel twin

Actually, it shouldn't be much different than a single-cylinder engine with equal displacement. I would think that it would considerable vibration.

@@wolfietigerstripes3248 like almost every classic British twin engine.

How do you think a single cylinder motor works lol

Yes! :) done it in my V8.

It needs separate exhaust per cylinder since the pipe size is designed for each cylinder to push out exhaust separately, one cylinder after another. If the exhaust is not separated, it would need 4 times bigger pipe to get similar restriction as stock.

@@jjhack3r imagine how much back pressure there is in it.

@@jjhack3r may also be a little lean as well carb feeding four at once

It’ll be a torque monster

your car is broken🤣🤣

they have it all everyone favorite goodies🤣🤣🤣

I think cam as well. Looks like intake valves were leaking on cylinders 2 3 and 4 on the compression stroke.

👍

Pretty sure they know that.

My thoughts to, it's one whole revolution without firing. So the engine fights against it's own compression? Until the exhaust valves open 🤷🤔🤔

A rocket is one stroke.

your mums a one stroke

I came here purely to find this comment as it's exactly what I thought when they put that in the thumb nail. For someone with so much tech expertise, making a mistake like that surprised me!

That's just normal for a Lada. JK

Haha yeah torque monster

And a bigger flywheel, I'd say

I'd expect the welded crank to give before it generated too much torque lol not sure. Would definitely be interesting to see though!

Put a giant exhaust so loud it will wake up all the neighbors 😂😂😂😂😆

Why would it produce more torque?

🤣😂👌

“Put me out of my misery!” Lololo

😅😂😅🤣😅🤣👍 Poor Lada!

You can not kill a lada!

"Later"

Technically the stroke is when each operation of the piston occurs. A one stroke would have intake, power, compression and exhaust in 1 movement of the piston which isn't possible. The closest is this ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ceyQvUldiBk.html imo at that isn't 1 stroke

Exactly.

@@cudwieser3952 you can actually build an engine that has the intake, compresion, power and exhaust in a single motion. it's called a turbine. pistons need at least 2 strokes to work.

@@anonym3017 True, but to split a hair turbines don't reciprocate and use strokes. That said the wankle would meet your definition.

@@anonym3017 yes you can make 1 stroke piston engine if it runs on steam its possible steam engines have double acting pistons

Lmao

"It's spraying gas!" "I saw that, it's okay, I have a fire extinguisher.." 😳🤦🏼

"fine"

Thats just it's insane slav harbass swag!

@@iamiam8407 spraying gas and kicking ass

Exactly! I would think of this engine as one of those single cylinder giants back when oil its self was used for power generation

@@olekdah you have 4x more friction and 4x more compression to overcome after all that friction, that's why a larger flywheel would help. I don't think I have to explain the other point he made about the carb being half powered right?

@@olekdah troll

@@olekdah Then explain how a 4 cylinder 4 stroke engine where it normally fires pistons 1 and 4 on first stroke , then 2 and 3 on third stroke, being made to fire all 4 on the same stroke is not doubling the required volume of fuel and air from the carburetor?

@@olekdah yes I do still think you're a troll because you're completely ignoring the context, this is no longer functioning as it would a normal 4 cylinder 4 stroke. It is a 4 stroke still but it does not fire twice within one full cycle. It only fires once, all at the same time, therefore the carb is a choke point as all four cylinders are demanding fuel and air at the same time vs only two every half cycle. It's like you didn't even watch the video you just go around and comment about how you know about engines. Random people online are not who you should seek approval from.

This would be a good project for the $50 AMC eagle

I think this is due to all cylinders pulling in air at the same time, when all of the valves close the at the same time that air hits a brick wall and has to go back out the intake through the carb.

@@nilssjoberg2522 yes, same thing lawnmowers do with the air filter off. You will see fuel spraying back out the carb a little bit with high speed camera.

You need more carb! The cylinders are all fighting for the same air and fuel at the same time, then the valves all shut at the same time and causes reversion. Fuel injection would be better.

Lawnmowers that do this is from crankcase pressures, is why most used oil out of em smells like gas. Excess will blow by the rings and create pressure in the case which will vent off back into the carb. I think excess gas in the carb is because of efficiency or lack thereof. Fuel injection would blow by and feed out exhaust if pressure got high without any pcv system.. but i dont fully understand how egr systems work as with pcv systems so i could be completely wrong.. good learning point tho..

Exactly, it's still 4 strokes.

DR800, who's she?

With a shit ton of valves!

Chevy just released a 10l V8 Race Engine. One Cylinder has almost 1.3l.

@@beaterbikechannel2538 is

Yes i agree, needs 1 carb per cylinder or twin carbs at least.

Needs a blower!

Yup, that's exactly the reason! A ton of airflow needed (so a lot of vacuum) at the power stroke, but carby can only provide 1/4 of that, since it's only designed to feed one cylinder at a time

@@hojnikb Thats correct, but i feeds two at a time in most 4 inlines.

Here’s the thing. It will easily make more power if the exhaust pipe is either removed or replaced with a straight pipe exhaust as there is way less restricted air flow from the exhaust stroke

A trabant would be much better

Aaand... it will work.

Ikr? When it comes to manipulating the automobile, they do stuff that we wouldn’t dare waste our money, time, or risk our lives on. But at least, through them we get to see what exactly WOULD happen if you did.

"is did a thing, and learned much from it. So is know what is done. Then we can not know what doing next." much is the wisdom of the soviet mechanic.

jigging is everything.. but I still dont know how that primitive jig set up worked.. yes indeed, skill and intuition are on display.

I _had_ a grandfather who was pretty good at welding

​@@paulg444when you're used to working with pig shit, you start getting good.

Amennn 🙂 🙂 🙂

and it works badly because on 720 ° of crankshaft it receives once all the torque and all the power then nothing for another 720 ° of crankshaft

@@Amin_846 actually it works badly because there's not enough flywheel mass. Plenty of single cylinder 4 stroke engines exist

@@joelaw728 its effectively one large piston though the carb is undersized and it would require a larger volume of fuel and air to run properly and a larger crank to maintain momentum

Do you think they should have added a ballancer at the front of the engine to lower the vibrations and maybe helping with the full engine cycle?

The crank welding was the most impressive, getting all four to move as one. It wouldn't have taken much to reprofile the cam and get 2 cylinders to fire alternately. Giving a power stroke every 360. Just like a double fiat 500 engine.

I was about to comment saying that video title is wrong and thats its still a 4 stroke engine, you kinda bet me to it

Its literally just an unbalanced 4 banger XD

At first I was wondering wth they were talking about with the title in this video. Once Vlad started talking it made sense, but that title..... edit: just a thought to add to what the original comment said, a 1 cylinder 4 stroke engine might also be the first gas engine that many people were exposed to back in the day via stuff like old generators and even providing the tumbling/turning movement in old clothes dryers.

Yeah I saw the title and immediately thought the same thing. I've only ever seen 1 type of "1 stroke" engine and thats a pylon hammer.

Machinists, engineers, car enthusiasts, students...

Rothschild?

And possibly a points ignition instead of what looked to be a Hall Effect rotor.

This is a great point.

A carb per cylinder then :P

I bet a vacuum gauge on the intake would go nuts and toss its needle.

Yes-yes!

I think the same. One carburetor is enough for four cylinders, but at the old setup, only one cylinder needed the fuel at once. But now all four cylinders need the fuel in the same time, so that carburetor can not deliver enought fuel-air mixture!

For decades there is a reason why these were never built, they don’t work for crap. As an experiment it was interesting, but the outcome was already known by anyone that has worked with engines.

its not actually one stroke its still a 4 stroke engine

@@Videoswithsoarin exactly right, I don’t know where they came up with one stroke.

Я не знаю что я делаю, но всё ХОРОШО! 😎👍

"Enough with the chit chat, let's do this!" Much better isn't it

Actually, they changed the meaning a bit translating from Russian to English. He really said: "I anticipate they're gonna say (in the comment section): "he understands nothing", but don't worry that's ok, I'm sure many mechanics will be interested in figuring out how it works too". He meant it was very special knowledge and lots of mechanics who worked with this engine didn't know it too.

@@maratbabayan9332 Good insight, brother. Thanks for the translation, it makes sense given what they were working with. Drawing from my own experiences working with engines… well, I’m way more like BMI’s translation! As an amateur, I usually have no idea what I’m doing. But with a wrench, a manual, and the confidence these vids give me… I know I’ll get it running eventually.

What would a one stroke look like... I'm imagining two side-valve heads mated together at opposite ends of a cylinder, a piston with conrods on both ends going straight out through the head and two cranks. At a certain point it's easier to just build a double acting steam engine

It's actually a big bang engine where all cylinders fire very close together or at the same time

@@PKMartin a one Stroke engine is when the piston can only stroke the barrel once. For example.. A gun.

I think a turbine engine would qualify as a one stroke engine since intake, compression, ignition, and exhaust all occur concurrently and continuously. Though it's not reciprocating so it doesn't technically have "strokes".

@@Javaritto correct, a turbine engine does not have a piston to stroke a barrel which it doesn't have either...

Drip-54

Ai read your mind!

Yeah I figured the same. It's like it's running at the equivalent half or quarter the rpm of the normal set up.

Not only is it in one huge pulse, but the entire second rotation is operating on momentum. I'm wondering how it would be if you kept the same crankshaft, but changed the cam and ignition to fire alternating pairs of cylinders (i.e., 1&3, 2&4).

Briggs and Stratton has an engine called the oppesed which is 2 cylinders firing at the same time. It uses a waste spark type system

Theoretically if they had a flywheel opposing the weight neutralising the imbalance then I think it would be driveable, but let’s not forget the camshafts are also out of balance, it’s just horrible to think about what that poor engine is going through 🤕

Wouldn't the exhaust be a real problem too? All four cylinders trying to cram out the air at the same time? Probably would do a lot better straight with no manifold.

No stranger to motorcycles and from God's own county!

Kind of.... 2x2 would be alot better... but....The carburetor is calculating fuel per air volume. It may be underrated for the peak air flow at revs but it will still be aiming for the same air fuel ratio regardless of number of cylinders. There may also be some preference in manifold flow that starves the end cylinders of air fuel volume comparative to the center cylinders. The main issue that your 2x2 idea would solve is the lack of inertia the 1x4 system has. The lack of inertia means the spark timing had to be retarded and as such a lack of good flame front would have hindered max rpm. With a 2x2 system the flame front can be a bit more advanced as the inertia will carry it past tdc allow a more successful power stroke due to a more health flame front. Generally it takes about 6ms for a flame kernel to propagate to useful power stroke so spark fires 15-40' before tdc. When this is done counter rotation forces are applied to the crankshaft at about 20% of the power strokes force. The other cylinders and stored inertia in the fly wheel over come this and compress it to be store as potential energy in the compressed gas until the cylinder passes TDC where it assists in the power stroke. But with all the cylinders firing at the same time the counter rotation force is too high and wants to stall the engine, or slows it enough that usable power stroke has already been mostly expended. A very aggressive centrifugal advance may assist this as the low speed low inertia timing could be very retarded but at higher speed the timing could advanced more than usual to counter the initial retarded timing to aim for gradiant to 30btdc at 3500rpm.

i was thinking about that. Maybe if they used forced induction and injectors it would open up possibilities for it actually make some tourqe?? i don't know, just thinking out loud

@@shanewilson3653 whilst that may be true, the fact remains that for this to run, the carb and intake (before the 4 branches) needs to be around 4x larger. The fuel ratio may not be out of tune, but the maximum flow is nowhere near what it needs to be. Wide open throttle is barely giving each cylinder 25%, even without flow starvation. The vacuum advance on the distributor is no doubt incorrect too! Exhaust has a similar issue, back pressure must be immense!

I’m starting to think these engines are indestructible

@@peterbuckley3877 yes......yes they are. You understand them, and enjoy their brilliance.

Hello Algorithm, this is a good idea, lets push it.

Commenting to boost this idea 🔥

Aggree! 👍🏻

Agreed. I'd go for a single electric motor and rock one of those industrial ac unit motors welded directly to the transmission. If an old Honda can drive with 80hp a Lada can haul ass with an ac motor. Lol

Let's go!!!

I did think the exh manifold would be choking at the massive rush of air at once. I reckon the cam was not spot on or the valves didn't close fully causing backflow through the carb. Interesting video tho

Yes! Exactly what I was thinking. Its choking itself when all 4 cylinders are trying to get air and then exhaust it at once with the manifolds it has.

I was thinking about the same thing.

Vlad- we don't know what we are doing Result: reverse engineering engine using only basic tools and on shoestring budget

Just wait until they get a laser cutter or a CNC machine

yes... combine the 5 flywheel video with this one...

Yeah, indeed. I thought the same and searched for "fly wheel" in the comments :))

You can't make this run better. It behaves like a huge single cylinder engine.

@@jakubukleja2553 true, it'd need a relatively heavy flywheel to keep the spin happening. an option would be a twin firing super thumper, firing 1+3 and 2+4 alternating. crankshaft is already there, cam needs a redo. it'll still be a jackhammer, but might actually run up some rpm with torque

It work with just one carb too if that'd be easier. The old 360 degree crank twins from English motorcycles can work with just one carb because even though they both go up and down together only one is sucking at a time. Very bad engine balance. I didn't watch the entire video, just noticed typing this they didn't set it up were each piston is doing a different stroke of the cycle. That'd of been better. All moving at once but doing one of the four strokes each. That's how the old British twins are I mentioned already. This is basically running like a single, not smooth at all.

Absolutely!!! I don't think all cylinders were lighting off.

That camshaft welding and grinding looked like a nightmare 😂😂😂

@@Nathangies honestly didn't look horrible considering the tools used

They are ! Why do you think it’s jumping and shaking everywhere 😂

@@rypdx Rotating mass

I was thinking same thing with the exhaust. Most cams have a little bit of overlap and that's a lot of exhaust back pressure bouncing back from the restricted manifold designed for separate pulses.

@@davisphillips7792 exactly. Also I saw some blow back through the carb, indicating longer duration or to much retard on the intake lobes.

My thought exactly.

I thought it sounded just like one of those....who would of thought they would learn something watching Dave TV!!
