A crankcase is the largest and most integral part of an automobile engine. It is a metal housing that holds all the other parts of the engine together. Crankcases should be designed in such a way that they should be strong as well as light. They are usually made from cast aluminum or cast iron via sand casting. These housing enclose connecting rods, crankshafts, reciprocating pumps and cylinders. A crankcase protects the connecting rods and crankshaft from foreign objects and keeps the motor oil contained.
