so, I have been thinking (not always a good thing)
If an engine is basically an air pump, and the objective is to make it as close to 100 percent efficient, why is the exhaust valve so much smaller than the intake valve? Forget emmisions, forget fuel delivery, just want to understand why this is so...it is so on most engines... Rich |

that has to be BS with regards to engine size and cylinder number......a chevy V8 350 cubic in motor has pistons the same size as a /4 motor with that theroy, no V8s would be bigger than 4.4liter and the Chevy V8 has models up 454 cubic inches (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) plenty of inline 4 motors with 2.4, 2.5 displacment and larger.... |
