The greatest number of cars uses piston engines. The four-cycle piston engine requires four strokes of the piston per cycle. The engine is assembled of various cast pieces: its foundation and main stationary body is formed by the cylinder block with the top portion of the crankcase to which the cylinder heads and the bottom portion of the crankcase are bolted. The crankcase with its main bearings houses the crank-drive assembly, comprising the pi­stons, the wrist-pins, the connecting rods and the crank­shaft. Besides, the valves, valve-operating mechanism with camshaft, control gears and valve tappets, ignition system, carburetor, water pump, fan, fuel feed pump and oil pump are parts of the engine.
