Abstract
A method and apparatus for delivering a mixture of fuel and gas to a combustion chamber of a compression ignition engine. The method and apparatus includes compressing a gas to a pressure sufficient to initiate combustion of a fuel, delivering a stream of the gas toward the combustion chamber, injecting a quantity of fuel into the stream of gas to create a near homogeneous fuel and gas mixture, and delivering the fuel and gas mixture to the combustion chamber such that combustion occurs substantially within the combustion chamber.
