Abstract
An engine piston composed of a head and a body separately formed from the head. The head is of ceramic material and the body is light metal or light alloy. The head and the body are connected against axial movement by interengaging means provided on the head and body by rotation of the head relative to the body, and the head and body are then fixed against relative rotation by an anti-turning device, this arrangement preventing development of excessive thermal stress. The piston is of reduced weight, can be mass-produced, and reduces fuel consumption.
