Abstract
A fuel injection system is disclosed for an internal combustion engine 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. Fuel feed means supplies fuel to the compression chamber, and nozzle means is operative to substantially confine the air in the compression chamber during its compression and to discharge the compressed air-fuel mixture as a jet into the combustion chamber.
