MOVING PARTS OF AN ENGINE
The moving
parts of an engine serve an important function—turning heat energy into mechanical
energy. They further convert reciprocal motion into rotary motion. The principal moving
parts are the piston assembly, the connecting rods, the crankshaft assembly (including
flywheel and vibration dampener), the camshaft, the valves, and the gear train.
Burning
of the air-fuel mixture within the cylinder exerts a pressure on the piston, thus pushing
the cylinder down. The action of the connecting rod and crankshaft converts this downward
motion to a rotary motion |
