Internal combustion engine fuel injection system

Abstract From the Canadian patent

A fuel injection system is disclosed for an internal combustion engine m e having at least one cylinder and a piston operating therein to define with the cylinder head a combustion chamber wherein air is compressed while the piston is moving to one end of its stroke. The system has pressurizing means adjacent the combustion chamber which suddenly further compresses in a compression chamber a small part of the air precompressed in the combustion chamber to a substantially higher pressure and temperature than the peak pressure and temperature of air in the combustion chamber so that improved control and quality of combustion results. Fuel feed means supplies fuel to the compression chamber …
