Car Talk: In Case You Needed To Know

A friend who thinks I should know more about car engines, has been tutoring me on how he learned about the piston engine. He tells me there are only four words to remember when it comes to car engines:

SUCK--intake of air and fuel into the cylinder through valves (downstroke)
SQUEEZE--compression of fuel-air mixture (upstroke) valves closed
BANG--combustion of fuel-air mixture (downstroke) with spark plug valves closed
BLOW--burned fuel-air mixture (upstroke) exhausted through open valves

Honestly, this is exactly the kind of stuff my kid is always asking me about. I should bookmark this.
