This is the best achieved with the proper amount of lubricant oil film on the piston ring cylinder contact point and complete contact of the bottom of the piston ring against the piston groove. Therefore, the

Nearthe top ofthe stroke, the spark plug is fired, igniting the mixture. 3. Expansion. The burning mixture expands, driving the piston down and delivering power. 4. Exhaust. The exhaust valve opens and the piston rises, expelling the burned gas
