Abstract
Disclosed is an internal combustion engine having a reservoir in communication through a passage with the combustion chamber. A valve is provided in the passage to enable the reservoir, when the valve is open, to receive a fraction of the air during the compression stage of the engine cycle. The valve closes in response to a decrease in pressure in the combustion chamber. The valve is automatically controlled to open at the beginning of the next compression stage to inject heated air into the combustion chamber. The valve then remains open to enable the reservoir to receive a fraction of air from the cylinder during its high pressure cycle for restitution to the cylinder chamber at the beginning of the next compression stage.
