Abstract
A four stroke cycle internal combustion engine is disclosed with means to provide auxillary pumping of air directly into the cylinder. The piston head is provided with a sliding valve which is self-acting for injecting air into the cylinder during the intake stroke, and to inject air into the cylinder during a portion of the expansion stroke. An air pumping chamber is formed between the lower portion of the piston and the cylinder carries a self-acting sliding valve which controls the flow of air into the pumping chamber.
