Abstract

A two stroke internal combustion engine having an intake piston which feeds air to an adjacent power piston. Both the intake piston and the power piston are held in oscillating cylinder assemblies and the piston rods are integral with the pistons so that the piston rod is always in line with the piston. The cylinder assemblies are both supported by trunnions and the air from the intake cylinder assembly is fed through an opening in the center of the two trunnions between the intake cylinder assembly and the power cylinder assembly. Preferably the rod portion of the intake piston and rod assembly is shorter than the rod portion of the power piston and rod assembly.
