Abstract
An internal combustion engine having a plurality of combustion cylinders configured to operate in a compression ignition mode. A pressure sensor is provided to sense pressure within a combustion cylinder of the engine. A combustion control system, including an electronic engine controller, is configured to receive electrical signals from the pressure sensor and, based on such signals, determine a maximum rate of pressure increase occurring in the combustion cylinder during a first time interval. Based on the determined maximum rate of pressure increase, the combustion control system is configured to control one or more charge inputs to the combustion cylinder during a second time interval.
