Abstract

A method of operating an internal combustion engine includes the steps of: igniting a diesel fuel and air mixture in a combustion cylinder using spark ignition; sensing knock in the combustion cylinder; adjusting a spark timing and a fuel injection amount in the combustion cylinder dependent upon the sensed knock; and igniting the diesel fuel and air mixture in the combustion cylinder using compression ignition.
