Who Can Build a Piston Powered Engine With the MOST Horsepower?

Today we're back in Scrap Mechanic with a piston powered engine build off! I've invited Kosmo to come join and try and build his first piston engine and we're going to compete to see who can build a 4 piston engine with the most horsepower on the dyno!

i am a little curious, is there a way for us to download your mods in the workshop and all? i don't even have SM i am just asking for if i ever get it, i don't think an I3 runs it though.

[@thecaptainnoodles]

kan maybe you need someone to cut down your ego and do better than you lmao.

[@YupGod]

Here is my tip for you: The sensors and logic gates all have a 0.025 second delay, so the faster your engine goes, the worse the timing gets. This means that you should advance the timing as the engine goes faster.

[@drphillow285]

You should try hook up your explosive engine on the dyno, maybe you'll be able to make a car using it after all this time

Please, please do a piston powered survival run. It would have lots of different vehicles with differently tuned engines for different roles of the vehicles; like a high torque slow speed for a crate carrier, or a really small high speed low torque to power your drills. It would make you create lots of unique, industrial and cool looking vehicles due to the new and really interesting constraints introduced.

For one of those big 7-8 extension engines, you should look into the massive reciprocating steam engines of the old ocean liners (titanic style yk). They are feats of engineering and would be awesome to see in SM.

I wonder if it would change the hp value of you changed the firing order? Might help with balance like if it was 1,4,2,3

[@andreamarchetti1010]

Hey kan, i was thinking if changes the initial rotation of the pistons would make a difference on the dyno. Like now you have a sequence of 1-2-3-4 when the piston goes down, maybe try 1-3-2-4 or others configurations. Or you can even try to put less angle on each piston like 60 degrees instead of 90, but I think it's a little more complicated.

[@GremlinSciences]

Putting less angle between pistons helps but requires a matching number of pistons, so he couldn't use that for this challenge. You cannot make a 4-piston engine with just 60° offset, you'd have little to no power for 1/3 of each rotation unless you use a multiple of 6 pistons. You want to always keep the offset as 360/c with c being the number of crankshaft cams (which should match the number of pistons unless you're getting fancy with multiple pistons on each cam) Changing the activation/firing order of the pistons can squeeze a tiny bit more performance out of the engine, but it's mostly done to reduce vibration and wear. If you're referring to the starting position of the cams (ie, you mean he should have made the crankshaft start as an _x_ instead of a +), that really only effects the starting torque. It would let the engine start under a larger load, but it wouldn't increase the actual power or speed of the engine.

[@jakeblohm3133]

Try with not welding them on the ground, I did some testing and they worked better and more consistent.

[@termisher5676]

How about adding multiple piston engines to single gear shaft and powering the torque meter?

[@Wheagg]

In my experience, each piston pushes at a certain pretty exact point so they end up fighting each other on specific rotations

[@termisher5676]

@@Wheagg you could easly synchronize them

[@theredstormer8078]

It's been shown in previous videos that balancing does make a difference. Why not make the crank look more like those in real engines? What you have is sort of a weird unbalanced crossplane crank.

[@ig-rd5923]

If you are talking about the unstable inline 4 Kan made, the problem had nothing to do with weight, it was simply that piston nr1 was blocking the view of sensor nr4 for a split second.

[@phoenixdonner8553]

I think he built the locks for the wrong direction but i guess it didn’t matter in the end.

[@pweedos8482]

Im sure he did too. they need to lock from back (encoder) to front (output shaft) and he did the opposite

[@colb.e]

I was thinking the same thing, I’m glad someone else noticed, proves I’m not crazy lol

[@whoknows8864]

I think the locks are the right way if you are accounting for a heavy load on the output shaft.

[@Symbols_Cipher]

I would like to see you make a vehicle for both your engines.

[@wynexdra3082]

Are your torque locks in the wrong orientation? I noticed that your engine rotates one way at 13:17 and during all the dyno tests but the opposite direction at 21:37 (end of the video). By 'torque locks' i mean the linkages the prevent slippage along the shaft. See 7:33 where kAN builds them. At 21:37, it appears that the engine is rotating in the way that engages the torque locks. Whereas, at 13:17, the torque locks are disengaged and effectively useless. Same for during the dyno tests. You can even see a torque lock completely separated at 18:49 during one of the tests. (Please feel free to correct me if i'm wrong.)

[@zuky6404]

Please keep doing this series with the dyno it's amazing. So many new ideas with this dyno its insane

[@FishermanKyle]

should revisit the explosive engines. you could use the tnt now for smaller cylinders, and theres better logic blocks now you could take advantage of. want to see it hooked up to the dyno.

[@upsidedownairline9388]

The reason gas engines in SM produce over 7k Nm of torque is because those torque figures aren't unusual for torque at the wheels on real cars. It's just geared down a ton. Dealers usually quote the torque at the engine (before the gearbox) because it directly correlates to the engine's power output.

[@LunaIsOnYoutube]

Maybe, you guys should do a "Piston engine only" race or "Car recreation challange" where you have to build a car and it has to be powered by the original type of engine it had in real life!

[@lacoflife]

Love the vids I have been watching your channel for years. Loved watching the streams.

[@he-who]

Extending the crank wouldn’t increase torque at all. The crank is the shaft you connect to the dyno (output shaft). What you extended was the connecting rods, this would realistically give you more torque

[@spaghettiwaffles]

even though Kan's engine had less rpm I'm sure that could be fixed with a gear ratio it certainly has the torque to handle a high gear ratio

[@1mariomaniac]

Congratulations, your I4 engine officially produces more horsepower than a 1976 Ford Fiesta L 😆 Seriously though, great video, very fun to watch you and Kosmo build stuff!

[@massimoleandro4349]

You guys might enjoy Automation and BeamNG. The ability to make your own engine and vehicles and then drive them around is pretty cool. Great video :)

[@davidgreen3549]

Love this video 👍🏽

[@von...]

inline 4 engines are almost always never all offset by 90 degrees from eachother, rather pistons 1&4 are on the same stroke & are 180 degrees from 2&3. Flat Plane Crankshaft would be a good term for you to google to come up with some interesting ideas on where to take the content from here (btw, if you dont do this - then I am 100% going to start making some fire Scrap Mechanic videos that are gonna slap on the YT algorithm lol)

[@Nevir202]

0:14 except the centrifugal forces would be pushing it BACK IN!

[@EmileMenard]

just realised you've made a engine that would be like a diesel engine irl: long stroke, crazy torque, and good hp.

[@hunterfields2106]

What if you had a variable crankshaft with pistons instead of pipe?

[@joshjones3733]

That’s what I was thinking. You could vary the cam length by replacing the straight pipes woth pistons

[@jakubmuron9030]

I don't know if the locking system vibrations actually has any effect on the performance, also since you've decided to make it crossplane rather than flatplane, you introduced so much more vibration that the locking system balance probably doesn't really matter either way. It should be possible to build the crankshaft in one piece though since you're working with 90° angles. With a V you'd need the locking system though unless you're planning to build a 90° V.

[@Pystro]

Your axle locks were ineffective for most of the video. You would have needed to spin the engine in the other direction for them to do anything. (Or connect the load to the other end of the shaft.) You can see that at 20:12, the first and second cranks are pulled to be parallel. But then you swapped the rotation of your engine at 22:00, that's why the torque locks worked when you explained them.

[@Wheagg]

I'm personally more of a fan of increasing STROKE rather than CRANK length. Gives you the leverage without the RPM penalty. The locking mechanism was real clever, though. I'm gonna have to experiment with that one

[@theannihilator665]

how tf do you increase stroke without increasing crank length? they have a direct relationship

[@Wheagg]

@@theannihilator665 keep the crank like on a minimum-length motor, just put the rail that the piston sits on to rotate further back and have a rod before the piston

[@theannihilator665]

@@Wheagg no offense bro, but I barely even understood what you're trying to say, you mean having the piston further from the center of the crankshaft correct?

[@Wheagg]

@@theannihilator665 not your fault cause it's difficult to explain but basically you put more distance between the piston and the bearing above the crank. Now the crank is the same, but the piston is pushing at less of an angle, so you lose less of that torque from the piston pushing to the side

[@Maccaroney]

Really cool! Needs a proper firing order of 1324.

[@gatorage850]

funny Kan built an inline with a cross-plane crank and Kosmo built a V-engine with a flat plane. I would think it would work better the other way around... IRL flat-plane usually make more power for their less rotating mass.

[@ScareGaming1]

Kan you and kosmo should build a car or truck of your choice and put the piston engine In it and race them i think this would be really cool to watch

basically you've made a tractor engine, huge displacement inline 3 or 4 with low rpm but tons of torque.

[@TheBananaMan4321]

Hey do you have a list of Mods you use for this game? If so can you share what you list is?

[@Cloud_Shire_82]

hp=speed torque=strength torque comes from the power of the piston acting on the crank while horse power comes from speed of the engine and how fast it can roatate in a giving amount of time from idle to full throttle and rev limite

[@ig-rd5923]

Not entireley accurate. Torque is strength, rpm is speed, hp is just a product of those two factors(how much torque it can produce at a speed). For example, 100rpm 200NM will be the exact same hp as 200rpm 100NM. However, in real life, more hp usually means more speed because torque and rpm can sorta float around and change in a gearbox.

[@mrcanisterr]

color mode piston add 1 tick delay to response, u better just delete the un used block in the decoder

[@186scott]

I wonder if the torque with the piston engines on here would be different if you had it so it was doing the same sequence as an actual real engine so with 4 pistons you would have it goes 1342

[@joshuapham4490]

I think the problem is that piston engines are close to a 2-stroke in function then a 4-stroke which means you would need a different timing order

[@MannDesBootes]

[@vincentpanicucci9118]

What you where calling the crank was the piston rod the crank is what connects the rotation of the the piston to the transmission the rods are what connect the piston head to the crank the more you know
