A lot of missleading facts there

1/3 of the energy is lost to the cooling system, 1/3 to the exhaus system and 1/3 is actually being used for the actual work. https://qph.fs.quoracdn.net/main-qimg-3d3191ef606387ed443a85f5232683fa.webp

Losses due to the turbulence are imho not even high enough to be mentioned. While on the otherhand heat transfer from the liner and cylinderhead into the water and the piston into the oil system are not mentioned.

if ya see something you think needs to be corrected, please fix it! If ya see something that needs to be mentioned, and isn't, please add it!
