Patent ID: 7882631

Claim:
A method of combusting fuel in an internal combustion engine, the method comprising: providing an internal combustion engine having a predetermined compression pressure; remanufacturing the internal combustion engine by enlarging a piston, shaving a head or a combination thereof, thus decreasing a volume of the cylinder; introducing air into a cylinder of the remanufactured internal combustion engine; releasing a portion of the air from the cylinder during a compression stroke of the remanufactured internal combustion engine; compressing a remaining portion of the air in the cylinder such that a compression pressure of the remaining portion of the compressed air in the cylinder of the remanufactured internal combustion engine is approximately the same as the predetermined compression pressure of the internal combustion engine introducing fuel into the cylinder; igniting the remaining portion of the compressed air and the fuel in the cylinder; and exhausting the ignited fuel-air mixture from the cylinder.
