Abstract

The device consists of a pre-admission chamber connected to a each cylinder, to receive either combustible gas, or air depending on engine type. This chamber has an engine driven piston with a cam driven inlet valve. Gas, is drawn into the chamber, the inlet valve closes, and the piston ries compressing the gas. At the correct time the combustion chamber inlet valve opens. Gas glows in from the pre-admission chamber, the inlet valve closes, and the normal four stroke engine cycle begins. Compressing the gas first, gives a more complete combustion with reduce pollution and improved engine power and efficiency.
