Go to 32 piston engine

5:50 The shape of the L only offsets the timing, which you can counter by offsetting the angle in the controller. That is because the regardless of the direction of the L the sensor time in back and white doesn't change at all; it is always exactly half/half. The ray cast from the sensor is coming from the middle of it and is basically one dimensional, which means it has no area of detection. It's just a zero width line. So, the angle at which the black changes to white does not matter.

An obvious tip for steering: vanilla seat bearings have 2 angles in their settings. One is for going clockwise, the other one - anti-clockwise. You can just use the vanilla style steering and manually set angles to be different for inside and outside turn

Kan! you explain too much cool stuff in different videos! we need a video dedicated to the piston engine tech and everything that's involved (such as the pass-through, the gears (but they are pretty well explained in their video) and the 90º gearshift ) but not building a specific engine, just step by step, what's what and what's used for! there's little documentation on youtube and you explain things really easy and really indepth! but that knowledge is spread among a ton of videos and it makes hard to re-watch and learn. it's been like a year and a half i don't touch scrap mechanic (boring adult life is sad...) and i don't even remember how to walk!

Thank you for finally building that RADIAL engine. That RADIAL engine does have a lot of power. I would even say that RADIAL engine actually did exist in the real world called a Bristol Hydra. Now Kan, I did request this before. So thank you for finally doing this!

when a radial engine and inline engine have a child you get this monstrosity XD

I can’t wait for you to put all this in an actual car. Personally hoping for a drag build, preferably a Promod, but I’d love to see everything come together. The engine, the transmission, the looks, and see how it can do!

To tune for max torque you can set the pistons to the slowest setting and tune it to where it runs perfectly smooth at that low rpm. This make it where it does not run amazing at high rpm but it will not reverse direction and it will not stall out as easy. This is what I used to get 40,000+ ft/lbs with a large crank flat 8.

5 better alternatives to your collision-based 90° gears: --- 2 universal joints. Downsides: Can be non-constant-velocity, if you don't align them correctly on the intermediate shaft. I'm not 100° sure you can get a n intermediate shaft that is built at an orthogonal angle to a 45° angle. But it SHOULD very easily be possible to just build the shaft as an inherently 45° piece. You can alternate 90° pipe elbows or use wedges. --- Constant velocity joints Downsides: Good luck coming up with a way to get them built in scrap mechanic. --- Hobson's Joint. Downsides: I don't know if scrap mechanic has force-less pistons/suspensions; Size might be somewhere around 6*6*3. --- There's one even more obscure alternative that I've seen in a youtube video. I don't know the name , so I'll try to explain it: It consists of an axle fixed at 90° to both input and output. The next piece is an L-shaped piece which slots over that axle at it's elbow (with the two arms of the "L" pointing towards the input and output shafts, respectively). This piece slides along the axle and pivots/rotates around it by some 20-40° or so. The out-of phase combination of sliding and pivoting creates circular motion of the ends of its arms around the input and output shafts, which spins a crank arm attached to the end of the respective shaft. Downside: The motion of the arms of the L-shaped piece isn't fully planar. You'll have to account for some minor movement parallel to the shaft. And I again don't know if scrap mechanic has force-less pistons (for the sliding of the "L" piece along that intermediate axle.) --- Or just mount the engine "sidewinder style" (with the crankshaft axis parallel to the wheel axle).

Scrap mechanic survival chapter 2 is gonna be lit! So many piston engine vehicles! Also gearing is so important and I wish the devs would add proper gears to the game

Thats some real power!

love this video. thank you

9:40 you dont need to put the controller on loop. if you turn loop off you can set a predetermined angle and when you activate the controller with W it will go to that angle and stop there, when u hold S angle= default angle that you put in the first slot. Also yes you dont want your torque going thru the controller timing advancing/retarding bearing, unless you have a torque passthrough, you would want to have your output be on the other side

@@spacewalk3046 Problem is point with highest torque without load isn't the point with highest torque with load. Load on the system decreases RPM completely changing timing needed to make engine work smoothly. There is no good 1:1 comparison with real combustion engines, as they work completely different and timing is locked mechanically by piston going up instead of fancy timing wheels. Despite that it's not that different from driving manual car. Yes, most cars have a lot of meters, but most drivers only look at speedometer to make sure they drive within the limit, and even this is sporadically. Most of the time you eyeball the throttling of the gas pedal and what gear needs to be engaged. And it changes all the time even with same speed as inclination and declination of terrain change the load of the system. Not to mention manouvers like engine breaking.

Bro the torque over time is valid. It’s not “fake. The creators of the Dyno have put our multiple statements explaining why this is the case

You should put all of your piston engines on the workshop either separate or in a pack.

I don’t have the brain to understand what you are doing, but it’s amazing to watch things come together.

Nice! I didn't think an X16 was possible in vanilla!

How many bearings do you want? Nobody: Kan: Yes

They do exist. On planes. But they are literal stars with 5 branché instead of 4. Maybe try that next time if it's even possible.

Check out the FANT mod. I've been messing around with the gearboxes in combination with piston engines to avoid 90° gears. This also allows suspension to be possible due to less lag, you essentially treat it like a normal engine, but the piston engine is connected to an input bearing. Also if that mechanic isn't good enough, just as the name suggests there are multiple gears that change the ratio of torque and RPM

KAN uploads work perfect for my lunch break🤘🏼🤘🏼🤘🏼

If you put a timing wheel with the L shape at 30 degrees you will have it so when the piston is slightly past top dead center, it activates. This works in both directions but the angle might me supplementary

You need to get the mechanical parts mod. It’s a 9/10 for me

He never heard of radial engine?

You should build a trailer to load test different engines in that test vehicle

Soooo, you made a 4x4 radial engine? Cool as hell man

Kinda wanna see a radial piston engine made, think it would be a good challenge and really cool.

Comb gears. I think I mentioned it in the "one" piston engine video, but with a comb gear you could make a TRUE single piston engine. I just don't know how scrap mechanic physics would play with it. I also still forget the name of the gear transition that transforms oscillation into rotation that would be necessary to use it in an engine.

3:05 There's only one consequence that placing the pistons that way could have, as far as I can tell. The base of the piston _might_ be heavier than the head of the piston, which would increase the inertia of the drive shaft.

@Goldfish_Vender

8 ай бұрын

Tested this myself in the game. As far as I can tell, the weight is shared evenly between both parts of the piston. If there is a difference it is incredibly small, so small, it probably wont have any meaningful effect in this case.

WW2 tanks used Radial 30 (it did not share the same crankshaft), also there's those "W engines" I think VolksWagen has a W12 concept car (4 inline 3)! Ah I remember there was the "H engine" 2 Flat 6 engines connected by the gearbox in F1 (I think it was Lotus that did it, not sure).

the one whom made the Raft Mechanic mod has a mod for creating bearings that connect their rotational force without gears slipping if you want a more seamless setup for testing potential power transmission without worry of gear slip

Finally. Had a comment a while ago on this. + shaped engine all pushing and pulling at the same time.

A different sort of piston engine you could try would be the e-rex "one-stroke" engine, which is actually a two-stroke engine, but works sort of like a rotary. Though I'm not sure how well Scrap Mechanic blocks would work, because it requires circular ramps.

You could probably put the timing wheel on the outside of the engine, reducing the bearing slack in it, using a pass through. Just a random idea.

do you think it is possible to phase shift each set of 4x pistons so the you have 16 pistons that all start pushing at their own unique time? ultra-smooth running and there would basically be no dead point at all.

You should ajust the external connection point with bearings. I doubled my hp with that. Also you should optimize a i4 i got 101hp

Use brakes by applying pressure over the gears to stuck the back wheels axle

Boxer engine when?

If you haven't done it already can you post your engine or your other ones to the workshop?

I feel like there is a complex idea No one has touched on yet where you have the crank shaft spin around The Pistons only having bearings where two Pistons would meet. It would look like old biplanes where you had an engine spin around.

@brodywilson6874

8 ай бұрын

To elaborate further, it would be like having twin crankshafts and meeting pistons that would spin around a crankshafts. if you adjusted the distance between the crankshaft, you could change the leverage that the Pistons have on the crankshaft

Quick question: Is a proper X engine possible in Scrap Mechanic? IRL they are way too complicated and expensive for the power they output so.... maybe that will be the result in Scrap Mechanic? Also think your target should be a 700rpm engine since that is what modern pickup trucks have

Scrap mechanic gears are terrible, but there's a linkage that uses pistons and bearings to transmit power like 90 degree gears would. I designed a differential using those that can take 20 000 nm of torque without slipping at all!

the smaller part of the l is where the engine wanna turn towards so if the l is 3 blocks and 1 block going down on the left on the lift its gonna go counterclockwise and if its on the right clockwise

also kan when u add a load it will reduce the timing for more torque and thus get torque

If you ever need i have a full torque / power / rpm curve per timing angle from the middle of the 0rpm zone on my workshop (K0wp3R on steam), on ... well my quad 16... and the torque does go over 10k, precisely 12k at 105 to 130° from the 0rpm point.

you are using a 90 degree firing timing try go for a tighter firing order like in the v12, it might be easier to overcome the stal point that way when you fire every 60 degrees

He's gonna be on foot for a LOOOOONG time then, all the bearings, pistons, controllers etc needed even for a basic one would take forever to get

If you're trying to get something like this for survival you should hook up a trailer full of those food boxes as if you are travelling to the trader

Hate to say it Kan, but the X16 engine you made is possible. Some boats and aircraft i believe went up to X24 engines.

simple braking system: lift the back wheels of the ground more elegant solution: since pistons dont break because of torque, disconnect the driveshaft by piston contracting like a very bad clutch

I messed with the mechanical parts mod, and while it works, it's hard to build with and the sloppy flex in bearings and items clipping through each other really makes it frustrating to do cool things with them. you really have to limit torque a lot to do even something simple like a diff, or after a certain speed it just craters. they really need to let you adjust flex in creative. bearings that don't flex would be so nice

You really should try blocking the sensor's path with something to prevent the engine from spinning imo

Magnificent x16

Maybe try different firing order for your 4 piston engine, try firing order of a catapiller 3204 engine and 6 cylinder like c-15/3406 engine. It maybe change something idk For v8 engine maybe order of a 350 sbc or a ford 351. Not sure if it would change anything on scrap mechanics physics

Wouldn't this design be possible without offsetting the drive shaft? Just twist which sensor is attached to which piston at each crank set?

Idk if I remember correctly but didn't the T5 gas engine have like 7000-8000 Nm? If I'm right I'd like to see that try to pull against that 16 piston beast

why dont you make a sensor for piston 1 when its top dead center and then thats how the timing fires for it, it will change while under load and fire based on the first piston, this could help with preformance

Kan discovering why early aircraft had massive engines with many pistons to go fast

The bigger the gear is, the more torque you can transmit because there's less force further away from the center of rotation, since scrap mechanic let's objects phase through each other that's the only way to handle massive torque

Can't believe you actually made it.

Can you upload that piston crankshaft I can’t blueprint edit but I’m wanting it and the workshop doesn’t have anything

Wouldnt the timing wheel L change the preferred rotation of the motor

Could you make another survival piston engine but make it as efficient and cheap materials as possible

well there goes the need for fuel and batteries in survival. the only gearbox that I think could work without mods is maybe a cvt using two big cones and shifting where they meet up. im not sure if you could run a wheel between them, or if CM wouldn't allow it. I would say if it did work it would probably mean that you would need to remove the diff and mount the engine horizontally instead otherwise it's likely going to slip too much. seriously amazing engine though, and the love the indicator

I hope he notices each section of 4 shouldnt fire all at the same time, for efficiency it should stagger rapidly

10,000? that's over 9000! (tell'em Vegeta)

Title says it wouldn't exist in real life but technically it does already, just not in the same way. Airplanes had radial piston engines where you could have up to 8 pistons around 1 shaft and add banks of engines for more power. I think the biggest ever was 4 banks of 9 pistons totalling to 36 pistons. If we're talking about how it's done in Scrap Mechanic then no.

I wonder, can piston engines be built in RoboCo? The game has rods, gears, pistons and sensors.

The only practical difference is that the angle of the bearing that the timing wheel sits on will differ by 2*arctan(1/4)=28°. [edit:] one has to turn the timing wheel by +14° to get it aligned with top dead center, and the other one by -14°.

Kan did you know that the electric engine has actually lower torque than the gas engine but it's more like high RPM. That was some sort of shock for me. Building cars with electric engine instead of the gas engines means +100km/h to your max speed. And that's real. While gas engine can barely hit 165km/h, electric one gives 260+

We need another video working on the test car

I'm pretty sure the test vehicle with the 16 cylinder engine is having tire slip. You might need to double up the rear tires.

you should build this in survival and make it a truck that can pull anything.

put a passthrough inside the timing wheel and put the bearing on the controller
