ABSTRACT:
A method of operating an internal combustion engine including at least a combustion chamber having a piston disposed therein, the method comprising during a first number of cycles after start-up of the engine, supplying at least a first fuel to the combustion chamber, and combusting said first fuel and during a second number of cycles after said first number of cycles, supplying said first fuel and a second fuel to the combustion chamber to form a substantially homogeneous mixture, and compressing said mixture with said piston to cause auto-ignition of said mixture.
