I Built an Engine With Double Pistons for Maximum SPEED!

Today we're back in Scrap Mechanic with the fastest piston engine we've ever built! I decided it was time to try something ridiculous and in an attempt to break the 300 rpm barrier we've doubled up the pistons and are using both on each cylinder to generate more speed!

What other things should we build in Scrap Mechanic?

[@maxgaming4627]

A transformer

[@connergamet579]

I’d really like to see a fully mechanical car with steering, suspension, engine, transmission, etc.

[@szymonh8772]

You could try out this game called Besiege for some engine and physics madness in general. Anyway, that engine looks super powerful nice job ;)

[@Speedgaming802]

32 piston engine

[@akostorok5054]

Kan, I built a piston engine with a timer so you can essentially "shift" it, I think the car would run better with that. You can dind it in the workshop (toilet pump piston engine with gearbox)

[@_miobrot_603]

Just so you know kAN, the average in the dyno is a moving average. It only uses the values from the previous 5 seconds of it recording, so by pressing the reset button, you are completely wiping the table of values. If you let the engine run at the new rpm, it will update to be accurate in 5 seconds, but by pressing the white button, it takes 5 seconds plus the time it took to press the button.

[@rubeanie]

I don’t know much about modern day scrap mechanic, but as a programmer I can confirm this, that’s the only way they would do it

[@pandapip1]

@@rubeanie I would have done it by an exponentionally decreasing weighted average. It has the best balance of liveliness and accuracy IMO.

[@rubeanie]

@@pandapip1I don’t have any experience with that technique of averaging, would I be wrong in saying that’s essentially a biased moving average?

brother I'm a 34 year old construction Forman, I came across your channel cause I watch some gaming from time to time. I'm glad I did. its extremely interesting watching you build these engines. you are extremely smart. you build this stuff with ease. I realize you have been doing this for years but its pretty amazing to me. I am glad I found your videos, I'm learning a lot. I'd really like to see piston engine with any kind of trans and diff. I know how hard that probably is, but I will watch even if you fail. I cant tell you how happy I am to have come across your channel these physics fascinate me. p.s. sorry if this is difficult to read. I am terrible at typing, I have carpel tunnel.. the more I type the more it hurts the more I don't care about correct grammar and punctuation.

[@jamisonparker7504]

I have been really enjoying your piston engine journey! Please keep making content like this. I get so hyped every time you post one of these videos.

[@raszpc]

Instead of stall point to stop the engine, what I usually do is to rotate the sensor themselves so none of them see a the "encoding wheel". This way I make sure its "off" without AND gates that add delays.

[@benjaminfranklin329]

You can also just jam something in between the timing wheel and sensors to block the detection.

[@aytelonne6866]

by having pistons stacked, when the first one push, the second one get longer before retracting because of the speed, which loose you tons of performance (the "opposite" will happen if the piston were in the same direction)

[@michaelc.4321]

You realize that you can just have to controller loop -15 rather than +15 instead physically changing the gear in the back

[@davidaugustofc2574]

-Common sense- forbidden over here

[@PepperKatt]

man, not even that.. just right click the bearing 😭

[@Wheagg]

Would've required him to figure out the timing again

[@Ben-ic4kp]

@@davidaugustofc2574 call down

[@Nevir202]

For that matter, if he wanted selectable direction in his diff, he could build the gears on both sides, connected to pistons, to allow him to select which set is pushed in to engage.

[@RzExfeL]

This is definitely some cool stuff! Can't wait to see more!

[@maxdax55]

Thank you for listening to my idea. Good engine design too by the way! Love your vids buddy

[@blueflame_sm]

I thought about making an engine like this before, but I didn't get around to testing it yet. Its a cool concept which I think can be pushed further to 600RPM no problem due to the conrods and overuse of pipes. Overall this is a great lead-in for building a Kein-engine, so I better see one in the next video. Actually, I much prefer to see best builds next video, then a Kein-engine afterwards.

[@Thagrynor]

So, you built that little piston stack and showed how it jitters a lot. Does that happen when attached on both sides? Like, could you utilize that silly interaction as the movement? Because that seemed to move a lot faster than normal piston movement ....

[@quakxy_dukx]

What are you saying? To turn it into a boxer engine?

[@Thagrynor]

@quakxy_dukx I mean, in whatever sort of engine would work? More just to use the twitchy nature of the piston stack to produce the movement as opposed to sensors and a timing wheel. If a boxer works best for that type of in-line linear motion, then sure?

[@rubeanie]

@@quakxy_dukxthat’s what I was thinking, maybe making it a boxer, then you’d also have two pistons firing at the same time, increasing the torque (in theory)

[@quakxy_dukx]

@@rubeanie the problem is that with the con-rod configuration, having multiple pistons on the same plane is impossible as they’ll interfere with each other. So you’d either have to have an offset between the two (or more) lines of pistons or use the more standard piston engine configuration without con-rods (but idk if that’s possible with this double piston setup)

[@benjaminfranklin329]

That jitter is effectively unresisted by the vehicle using the slack between the two pistons, under load the jitter would be slowed down.

[@davidgreen3549]

Love these videos some much man 👍🏽

[@flamepanda9947]

This is so cool!!!

[@hansvonflammenwerfer2817]

I love how there's a new upload everytime i go to the youtube homepage

[@noelradhakrishnan4423]

Yeah, same here

[@jamisonparker7504]

When is the survival run with all this new found piston engine knowledge come out?

[@mihalydozsa2254]

instead of putting them against eqhother, you sould have put them on the opposit sides top and bottom of te arm that you made longer to prevent collision with the shaft. So it works like a steam engine piston.

[@tomstech4390]

KAN: Who's a good little engine!? Engine: spazzing prefusely

[@tontowmerlin5240]

Try a quad piston set up as opposed to a dual piston setup. That way you can push down evenly.

[@CaptainFlips]

Love these

[@shadowalker4302]

On the chasi you should try to use pistons to switch the rear gear, instead of just breaking it and replacing it.

[@rubeanie]

Love the video! But you should use this to make a boxer, might be more evenly balanced 🤔

[@brodywilson6874]

Hay Kan I think if you had two crank shafts you could simplify this design just put a bearing in between the two pipes connecting to the pistons delete the extended pipe pieces towards the middle so one pipe can connect to A crankshaft forming an L pattern with the Pistons and the part connecting the two pistons will spin around the engine. putting the two crankshaft closer to gather, would Decrease leverage and increase speed

[@blackwing2963]

Damn Kan really thought he ain’t good enough at piston engines and decided to learn everything

[@OriginalPiMan]

Considering he couldn't do the easiest level of the piston challenge levels he found, he's not wrong.

[@mukuldeep3488]

Con rod - that's funny :)

[@Real_Bo_Red_]

honestly, with this piston setup you could easily add more pistons without adding any bearings, would be interested to see how differently it preforms

[@thijsbeer1284]

nice vid

[@sambrown6426]

Hey Kan, I heard from Hyce that you calculated the terminal velocity of a Shay, and I was just wondering which Shay you used in your calculations, and what said velocity was.

[@Der_Yoloist]

0:10 that piston setups reminds me on some certain piston setups in minecraft involving sheep... *cough cough*

[@Orwrath2010]

man I just can't wait for this update to scrap mechanic for survival but then the only issue is I'll have to re-download it :P the survival part is fun as hell would also like to know if we are keeping the old save worlds or having to start anew, fresh start wouldn't be bad just finding a nice spot is prob the hard part :P but do need to be able to learn all blocks iin the survival even the big industrial parts

[@Pyrrhist]

The engine torque seems much more realistic and reasonable when you consider that your driving your engine with hydrolics rather than making an explosion machine.

[@Mr.KpDubs]

I had been pondering on the idea of using 4 in a grouping

[@shay5025]

Is there any way to use the pulsing effect of the three length-one pistons to get extra super fast rotation speed?

[@blueflame_sm]

Yes! those would be kein-engines or ratchet-engines, both are unconventional designs he mentioned.

[@ElderonAnalas]

Could you use the funky pulsing from the pistons set to 1 in series like that, as just, some kind of really fast system? Tho, I imagine the torque is bad, but that's what tremmel gears are for, yeah?

[@OliverWhiteTailAlexander]

I feel the more and more RPM you push out of your engines, the more you'll need good transmissions to use the power.

[@ScottaHemi440]

that engine is crazy.

[@aeresys]

This is the jankiest engine I've ever seen It's beautiful

[@TheMostUt]

I would put the diff gears on the body on pistons, so you could flip a switch and choose CW CCW on a whim. Not sure how close to IRL SM timing would be for engies, but would you want a IRL ignition timing map for a real running engine, maybe to try adaptive timing on these pistons engines?

[@manman-sg1zt]

Good thinking with stacked pistons. How about stacking even more?

[@the_falcon0power150]

Could you use the piston twitching to power an engine? Not sure what you could do to get the timings right though.

[@jeffreyblack666]

If you want speed, why not try a simple lever? Instead of connecting the crank directly to the pistons, connect it to an arm with a pivot off to the side, with the piston attached near the pivot. If you want torque have the pivot on the crankshaft side.

[@jaydnferguson8326]

Hey @kangaming wouldn't U think reducing the vibrations from the chassis would help increasing the torque delivery Like making the engine mount higher and keep it at 0%. Because angle of the engine might also affect the angle of the timing wheel or however the combined angles are calculated should mabye make a video on the most efficient way to mount the engines

[@charlieandersson4069]

use a heavy flywheel it will help the piston engine push past the stall points.

[@wisnoskij]

What about at a 90Deg angle? to pull and push diagonally. should be far more compact?

[@mmhmnms]

I'd love to see how that engine fairs on a chassis with wayyyyy less mass

[@ShawnF6FHellcat]

If you want to make something that looks even more cursed, put a piston in the connection rods, then set all pistons to distance 1.

[@thighnikky]

I wanna build that engine, and add a second line of pistons in this configuration at the bottom and see what that would do

[@youtubeSuckssNow]

You should try and make a steam train with pistons on the wheel that go up and down to make it move.

[@caydoncargill3989]

Now I want to rebuild some of my old engines with the survival mode pistons since they have more power

[@firenutter1798]

Imagine if that piston engine had a twin on the other side to neutralize the forces of momentum out side of it and then the wheel that's spinning from there was treated like flywheels that fed into the main transition point that actually gave power to the vehicle and because of them being two of them you can make sure there on the opposite piston position that's most optional there for just making even more nuts in power

[@timabailey1992]

I have a challenge for you. It’s in the work shop called “Kan fix this challenge”

[@waylonmorristexas4851]

Hoorah

[@marcoowskyy]

try to make a light car with 2 engines but 1 of them is like mirrored to make the torque glitches cancel out (maybe). And it should have double the power i guess

[@maxbackman7000gmail.c]

That looks like a vr6 engine but with 2 extra cylinders

[@bobisha772]

What would happen if you combined two engine types together? For example if you did 2 single pistons and 2 double pistons one one shaft.

[@wulfthemountaindragon5432]

Try pistons ontop of pistons, in one big long piston

[@spacewalk3046]

i don't know who told you a piston pass through is bad, its not the 2x1 ramp actually has slight collisions. If you have blocks or whatever collide to the side of them, it can help with containing the cranks position but honestly it's not ''better''.

[@Cosminox54]

This is pretty much like a Duel Overhead Cam Engine (DOC) engine. Lol

[@mig-21interceptor62]

Hook it up to some propellers in opposite directions and make a plane

[@1990Hazard1990]

If u stretch the pistons and give them 0 power from smart controller, u could go into the 1000+ rpm

[@Pyroturtle1]

Just how much power do the jittery pistons have? Is that something you'd be able to utilize to try to make an even faster engine?

[@EatLeadUCommie]

now all you need to do is make a 4 sided double engine

[@Adder6112]

If you build stops above and below the pistons you might be able to get more torque sice the pistons would be forced to push the crank shaft

[@thundercrowz]

It has the same hp and shape as my e30s m20b25 😮

[@EpicM147_NoVa]

Make a Double X 16 Piston Engine.

[@opamitstinkefinger9962]

hey kan, what are your thoughts on scrap mechanic and chapter 2?

[@MagicalPorkChop]

... Wouldn't stacking two pistons give an increase in speed while avoiding the 1-tick delay in the logic gate? If it meams that the crank distance increases, you could get higher torque but still rin at 300rpm.
