The fuel air mix just hangs there until the intake valve opens, where
upon the mixture is drawn into the cylinder. No waste. It HAS to go in
the engine. There is no place else for it to go. When the intake valve
snaps shut, compression is already well under way and a split second
later the plug fires. The piston reaches top dead center during the fuel
burn and peak pressure occurs just after the piston reaches TDC. As the
piston moves down in the power stroke, the pressure gives the downward
moving piston one heck of a kick driving it past bottom dead center and
on into the exhaust stroke. As the piston moves up on the exhaust
stroke, the burned gases are pushed out of the engine. Cycle complete -
ready for the next charge.
