Interesting cams, pushrods, and valves. Nicely done!

Wow, even thought that spawn engines were too weak to use. But when they are going fast, balls start to get out of the block.

2 The Likage: not gonna happend with this one. It's powerful as collision engine and no circle leak because they spawning with same velocity as piston.

300 kilo is not too realistic (some cars that use I4 are only 1000 kilo) Also, it should have more than 135 hp

2 altse99, no you wrong -) it's typical for diesel engine dimension and weight/power ratio.
For example "Kamaz" truck engine is 800kg and 250-300HP, and for smaller truck is 200kg/100Hp.

Elegant

Nice

btw that is def not 135 hp u convert angular momentum (J/s), 746 J/s is 1 HP uve got about 1.6 horsepower and dont be mad cause no one can make a crank on here faster 1500 rpms because of that the power is extremely limited and the best ull get hp wise is maybe 2.5 hp unless u put the density very high which then it will be to heavy to move

2000 Nm * 25 Rad/s = 50000 J/s = 50KW = ~67 Hp

Itzz, you wrong, go check your logic, how 1.6hp engine can move 5 tons truck?

@ killinich, sorry, I thought is was petrol

Rpm*Torque(Nm)/7124=Hp

2Christer, it's exactly the same what I've said. ~250*2000/7124=70
