Abstract:
1. A two stroke cycle internal combustion engine comprising at least one pair of cylinders of which one cylinder is a compressor cylinder and the other cylinder is an engine cylinder, each cylinder houses one piston, the pistons having a phase delay with respect to each other in a way that when one of the pistons is in one of the lower dead and upper dead points, the other piston is in a midpoint between the lower dead point and the upper dead point and vice-versa, the compressor cylinder being connected with the engine cylinder via a compressing pipe and the compressor cylinder has an inlet reed valve and an exhausting reed valve, while the engine cylinder has inlet valve from the compressing pipe opened by a pressure difference between the compressing pipe and the engine cylinder and closed by a spring force on the inlet valve when the pressure difference becomes zero, and the engine cylinder also has an exhausting channel including an exhausting rotative valve. the compressor cylinder having a diameter larger than a diameter of the engine cylinder.
