My shop teacher way back told me many times that "ambient air pressure" pushes air into a cylinder as it descends on the intake stroke rather than the engine creating a "vacuum that pulls air" into it on the down stroke. I sort of understand the difference but it's been a topic of conversation @ beer:30 .I think my shop teacher was right.
can anyone clarify? |
