The reason you make less power on the newer engine is because you modified the length of the crankshaft and when the game sees the crankshaft update it removes the connection of the crank with the cilinder. You basically have a 3 cilinder engine instead of 4

Try having multiple throttles, maybe 1 per 2 cylinders. Set lambda to .87 Increase volumetric efficiency and tune the RPM at which it's most efficient Change flywheel to lead (lead is apparently a lot heavier than tungsten in this game).

ITB would be crazy if it actually makes performance better.

[@Colfax98]

He's making less power because he updated the crank length and when that happens the game just removes the pisto from that section of the crankshaft

[@MonkGiatso]

why .87? from my testing lambda not 0 always makes less power, so changing it only makes sense if your going for fuel efficiency (lambda > 0) or thermal efficiency (lambda < 0) and as far as I know Thrm Eff is basically useless, I only managed to run my engine at 20 000 rpm tough, so maybe you need that thermal efficiency to get to 45 000, but at any usable rpm 0.87 just gives you less power EDIT: got my engine to spin 45 000 by cranking volumetric efficiency past 1 but Lambda: 0.87 still just made less power.

i absolutely love your videos, they got me into GB which i now love. i love these modular engines and played the pre-release to get used to them before the full update. i dont claim to be an expert but i have a few findings! the intake manifold could choke the flow into the engine, it may be best to keep the manifold small / have multiple throttles the alternator can be tuned to make a certain amount of power / apply a certain torque to your engine timing only changes the sound of the engine (at the moment) and wont effect performance exhaust is purely visual (at the moment) and wont effect performance the crank pieces can be adjusted (Shift + E) to set specific crank angles sorry if this has all been said! im enjoying watching you figure it out as i did. ignore the hate!

[@jacoboopy9150]

also, this is a game guys! its not claiming to be 100% realistic, and Kan can do whatever they like. the game doesnt simulate heat/water/oil/pumps so they just arent needed atm. if you want to build PERFECTLY realistic engines, go for it. but dont put others down for just having fun

[@MonkGiatso]

to a point a bigger manifold actually slightly increases power and having just the throttle on the block cuts power by like 10 %.

[@jacoboopy9150]

@MonkGyato oh thanks, didn't know that!

[@CreeperOnYourHouse]

Timing belts were briefly king, from the 80's to early 00's, then they went back to chain in the 10's. Unfortunately modern chain drives are awful and last barely any additional time more than belts, so gains are pyrrhic if anything.

[@AgentWest]

A carbon fibre exhaust? That ought to last a whole 5 seconds! Although doesn't look like the game cares about heat too much. Speaking of exhaust, would changing it to equal length headers affect anything? Or what about 4-1 (all pipes dump into one together) VS 4-2-1 (pairs dump into separate collectors, then after a bit more pipe those two dump into one)? And what about intake, is having equal length intake or four separate throttle plates better than just one? As for "no crank case", it was noticed, but there _were_ early IRL engines like that, so it's not really anything to talk about.

[@collinkaufman2316]

Lead is the heaviest material since it isn't classified as hollow, and naturally heavy

​@kuhljager2429 brake boosters work either by vacuum, which is sometimes powered vacuum pump. Or they're powered by the power steering pump

[@trilliongold]

I'm assuming most people didn't comment about the oil pan and stuff because that has no actual bearing on the function of the engine as it works within the game. Sounds like all the comments you mentioned are all ways in which people felt the engine would actually mechanically function better or more realistically within the game.

[@JohnTerreault]

Timing belts can run a water pump, too. The serpentine belt runs an alternator, power steering, water pump if not on timing, a/c compressor, and super charger. Some old vehicles had belts running to all of these individually. Some even had a smog pump in the 70s, 80s, and 90s that helped with emmissions.

[@ZantZ]

Just throwing this out there. Timing belts are still used. Also when a timing belt or chain snaps the valves don't get sucked in. Some will stick out based off where the cam is and the piston will push up and hit the valves. It'll bend the valves. But that only happens in interference engines. This doesn't happen in non-interference engines. In non-interference engines, the piston at TDC will never go higher than a fully open valve.

[@cummingtonite1214]

But I've seen plenty of valves get completely lodged into a piston and pulled into the cylinder in motorcycle engines. I guess technically not "sucked in"... But that's just semantics at that point.

Using the built in script mod "BuilderToolExt" you can have objects interlaced, just uncheck prevent interpenetration when attaching parts, so in your case this would be handy for 7:40 where you could put a cylinder inside the gear at a smaller size to not interfere with the gear's teeth and as long as the interlaced parts are not allowed to move separate from each other they not freak out. p.s. you can turn the script mod off and the parts will remain. can be saved, loaded, exported exc with parts intersecting :)

[@Kelita_penguin]

Make an engine with itbs (so have one throttle body for every cylinder)

[@baileybabineaux3725]

as someone who just fully built an engine from the ground up to make more reliable power i can explain some stuff, you can have a timing chain and or belt and that runs from the crank shaft to the cams or cam ( you can have a single over head cam or dual over head cams) and your oil pump, you also have the accessory belt that runs your water pump if that's not ran by the timing chain/belt, it will also run the ac compressor, alternator, and power steering pump assuming its not an electric pump, most of the time the cam doesn't drive anything outside of the engine but in the case of my car (2017 Focus St 2.0 ecoboost) the cam has an extra lobe outside the engine that is used to drive the High Pressure Fuel Pump for the direct injectors because direct injectors need to see more fuel pressure, somewhere in the neighborhood of 2000psi.. hope that make since hahaha hope i was able to shed some light on that for ya oh and P.S. a super charger is ran off of the crank shaft and that's why some people prefer turbos over superchargers because it take horsepower to spin a supercharger (parasitic loss) and turbos are spooled up using exhaust gasses so no loss of Horsepower

[@andrewslater6846]

I still think this is really cool. Suggestion… If you can make the side walls thinner it would be more realistic. Actual engines only have specific mounting holes on the sides rather than just a beam on the bottom. An i4 would have sides going straight down.

[@spritezAllManaged]

Hey um, idk if the exhaust matters but it looks like it does. Try to make each cylinder with the same length of exhaust. Having a 90 into the 4 cylinder exhaust pipes might be making back pressure higher. Thats why long lube is usually better for engines. Great video!

[@cserosbence9475]

23:10 the external belt drives the alternator the air conditioning pump the power steering pump (if the car has power steering) and on some cars it runs the water pump (and ofc the supercharger). Some manufacturers use 2 belts ( looking at you BMW) and have a dedicated water pump or power steering belt just cuz redundancy

[@ichdasjunge]

Longer piston rods reduce the friction on the cylinder wall, as you said the angle is more shallow

[@MsLordmatt]

Love it and love your content dude 😊

[@Yibadaable]

Just a note about the actual real-world functioning of an engine: Superchargers pretty much always run on an external "timing belt" which doesn't affect timing but has the same materials and dimensions as a really thick timing belt. Cam timing is provided by either a belt or a chain. Both are pretty much internal components but only chains are lubricated. The accessory belt runs the alternator, A/C compressor, and power steering pump in most cars (except the ones with fully electronic power steering. In a turbocharged vehicle there is likely also a vacuum pump running off the belt, and turbos are much more common than they used to be. In a hybrid, of course, very little is run off a belt (if anything), which makes them surprisingly simple to maintain. Overall though, traditional vehicles run every mission-critical system directly off the belt, since they were pretty much set up to function until the engine died. Brakes are the main exception to this rule, since non-commercial brakes run on vacuum produced by the engine (or a vacuum pump), and the brake booster is only airtight enough for a couple of brake applications after you lose vacuum. My favorite fun fact about engine vacuum: Some vehicles (notably early 2000s Ford trucks) use engine vacuum to actuate the climate control vents, so a bad vacuum hose or pump can leave you with a truck that only runs hot defrost no matter where the dial's pointing.

[@YugPatel-f8x]

I think you try playing stormworks again, it has been updated a lot, (in a good way), it now simulated everything from modular engines to gasses, and gas pressure to pipes, and cargo and trains, and more that I don't want to spoil.

[@jameshansen1903]

An engine doesn't necessarily need a wet sump oil pan to function. Lots of ye olde timey diesel engines were built to run with exposed crankshafts and rods with bearings that had to be manually oiled just like on a steam engine.

[@charlieandersson4069]

the lower the lambda number the more fuek it is adding, witch up to a point would give more hp

[@leonhardkortje6315]

My only guess would be that through the wrong ignition timing, two cylinders are firing at the same time, so more power is generated in an Instant 🔥🔥

[@jamesv6288]

For whatever reason, every time you resize a piston crank, the piston disconnects. Reconnecting the crank would get you more power.

[@catsarecool0824]

Now you gotta put some wheels on it

[@chazbennett7771]

I definitely recommend messing around with panel pieces so you can make it seem less bulky EDIT: there is a script thing in the game you can turn on to see power/torque curves, the dev points it out in one of the update pages

[@jeremiahmiller867]

the centrifugal clutch is like the torque converter in an auto transmission

[@gatorage850]

Timing belts are better if you have a non-interference engine like my 97 Camry. Timing belts have - less noise - less maintenance - soak up vibrations - smoother delivery of transfer - More direct (chains have slop and gears have play) this would make a belt more efficient at transferring power but only if the toque ways not too high (too much toque can cause the belt to flex) - less weight but since the belt is always in tension (more direct) it has more drag. almost like a gear that to tight. !!! but they will snap without warning!!! so I would only recommend it on non-interference engine!!!

[@401nailhead]

I really want to see this in a vehicle. A v8, or a boxer would be really cool too.

[@ninjia7347]

If you use a 1 to 1 ratio of carburetors to cylinders you get the maximum power which is why a radial type 54 cylinder 108 liter engine can produce a quite literal game breaking 6300 HP and 11000 nm of torque

[@themasterofdiaster6506]

the camshaft pully should be twice the size of the crankshaft pully so it spins half the speed

[@Astrolex12]

If I were to guess, the power draw on the alternator is negligible. The reason your engine with the bad timing shows better power is because the power output shows a single "frame" of power output. Since the timing is so wrong, you have 2 cylinders firing at the same time (i.e. 1+2, then 3+4) while your new engine has better timing (1 then 2 then 3 then 4) so the power output reading on the bad engine shows the exact frame when 2 cylinders are firinf at once where the good engine shows only one cylinder, hence the bad power reading.

That is the right piston firing order, its also what he made it in this vid. Those numbers aren't the piston numbers though. It's the assigned firing order. So 1 is the first 2 is the second 3 is third and so on

[@Pitstopcomponents]

Seems logical at first, but it actually isnt, because the center two pistons travel up at the same time, so they cannot ignite after 180° of rotation... your firing order would work if the crank is alternating--> up/down/up/down, but its up/down/down/up.... thats for eliminating primary vibration. If it would alternate, the engine would try to rock back and forth... on an inline six, its easy to figure out. start at 1, then go opposite side and move one inward(5), then repeat.... opposite side, one further inward...(3)... next would be 4, but one further means it begins back at the outer edge(6) 1->5->3->6->2->4 Also thats why Crossplane V8's rumble while Flatplane do not... a flatplane V8 is essentialy 2 Inline 4's but with the crank from one of them being 90° rotated... this means the firing order can be seperated to 2 inline 4's too... imagine cyl-bank one to be uneven numbers 1/3/5/7 and the other 2/4/6/8... firing order from a flatplane is: 1-8-5-4-7-2-3-6 alternating between left and right bank... crossplane V8's have uneven firing orders, still 90° appart like on a flatplane, but now its: 1-8-4-3-6-5-7-2... if you look at 1-(8-4)-3-6-(5-7)-2, you notice there are two ignitions on the same side of the engine after each other... this causes the exhaust flow to be changed from timed left right bank alternating, to left right left right-right... causing a bubble sound.... depending on your exhaust diameter etc. this bubbling is best hearable at certain ranges where exhaust flow speed and engine rpm makes the exhaust resonate... the bigger the tube diameter, the slower exhaust flow, the lower the rpm to get that bubbling really loud...
