Abstract
A method of controlling combustion of an internal combustion engine that use fuel injection and that uses lean and rich modes of operation. Combustion control values, such as for fuel injection timing and quantity are determined by a torque representative value. This value is obtained from estimated in-cylinder conditions and from engine speed.
