ABSTRACT:
An improvement in a four cycle internal combustion engine is provided whereby the crankshaft rotates at half the velocity normally encountered in conventional piston driven engines. In particular, the crankshaft undergoes just one complete revolution for every two complete cycles of the piston. By virtue of its reduced rotational velocity, the crankshaft is more easily geared to the rotational velocities of wheels of an automobile, and permits use of a simple valve-lifting mechanism. The improvement involves the interaction of each piston with a trammel crank mechanism.
