Abstract
A pneumatic direct cylinder fuel injection system for an internal combustion engine includes a pneumatic injector for each cylinder so as to supply a pressurized air/fuel charge to an associate stratified charge chamber forming a part of the associate combustion chamber preferably during the compression stroke of the associate piston, the quantity of fuel being supplied by an electromagnetic fuel injector. The pressurized air for the system can be supplied by an electrical or engine driven air pump or preferably the engine itself can be used as an air compressor with each cylinder having an air source control valve operatively associated therewith to control the flow of pressurized air during the compression stroke of the piston in its associate cylinder.
