modular engines weak? or am i dumb?

[Thorkin14]

cant figure out how to get power out of my v12 engine. it runs great and is set up really well but im only getting like 2 knots lol. rps is at like 14. compared to a regular engine im getting nothing.

Now what happens if you remove cylinder 3 in each row and put an intake there instead so you end up with 8x intake+two cylinders. In my boat that was way more powerful, and I don't _think_ I changed anything else.

*remember to add exhaust of course

The bug relating to adjacent cylinders is the one I discovered. IF cylinders are connected inline, they are forced to share the same inlet, massively reducing power. So you won't notice anything if you have one inlet and exhaust per bank.

However, it reduces engine breathing to the extent that you can sometimes double the power of a design by halving the cylinder count.

I have built some very powerful engines, and some that OUGHT to have been very powerful, but turned out rubbish thanks to this bug.

It is possible to replace 3 medium diesels with a mere 12 cylinders, but due to the way the standard engines were bodged, and the dodgy way torque works in the game, they are not a drop in replacement.

It is hard to track down exactly WHAT is wrong with the modular engines, but yes, something is wrong. I have built a dyno for testing, and it raises more questions than it answers.

I made a small car with a 4 cylinder engine. The first gear has a 3:1 ratio in the direction that increases torque and the acceleration is terrible. I had to add an electric motor that engages a little to keep it from stalling. Outside of that the thing has a top speed of 152 km/h. I don't remember what the highest gear ratio was. Has a controller that limits the RPS to 20.

The engines seem to have really bad torque but once a vehicle gets going they have no problem. Weird.

Can you tell me how you made the rps limiter? Its so annoying with it just overheating because of maxing out on 60 rps

I was using threshold gates and a numerical switchbox because I don't know how to use PIDs. The same method works for making an engine idle. Also, since some updates have happened and I found out that you can use more than 1 air intake manifold I've managed to get a lot more power. So much that the car has a hard time staying on the ground.

modular engines are insanely strong in giant sizes
depends on how ya build it

[Matthew Liberty]

The engines are actually fairly powerful, you just have to transmit the power well. Also be wary of the fact that clutches and gearboxes reduce output power by a few percent. Mod. engines also heat up a lot faster with increased loads, in other words, heating up is not just a function of RPS. Here is a very compact career car I built, the engine excluding the powertrain is just 4x3x2 blocks and outputs enough power to climb the highest mountain on sawyer island on 4th gear without stalling! https://steamcommunity.com/sharedfiles/filedetails/?id=2407740608&searchtext=

Actually they are really powerful if done correctly. Even a 4 cylinder should be plenty when using a truck. But if you use an ecu that doesn't adapt to the amount of air getting in the engine you can't give as much power as you could. I get 2600 horsepower on my 8 cylinder which is a 3x3 crankshaft at 27 rotation per second. Also that is without infinite fuel, just a good engine computer.
