Abstract
A method of operating a combustion ignition engine comprises introducing an amount of a compressibly non-ignitable fuel into the air induction system of a compression ignition engine during the intake stroke of the engine and then injecting an amount of compressibly ignitable fuel (e.g., Diesel fuel) in the cylinder chamber at a crank angle sufficiently advanced during the compression stroke of the compression ignition engine such that the compressibly ignitable fuel and incompressible non-ignitable fuel ignite and combust such that substantially all of the fuel in the cylinder is combusted, where the amount of compressibly non-ignitable fuel introduced into the cylinder has an energy content that is at least about 50% to at most about 99% of the total energy content of the total amount of fuel introduced.
