ABSTRACT:
A multicylinder homogeneous charge compression ignition (HCCI) engine with a control system designed to maintain stable HCCI combustion during engine speed/load transitions by: (1) determining “combustion parameter” values such as the maximum rate of pressure rise for each cycle of each cylinder, (2) adjusting engine operating parameters (such as charge-air intake temperature, intake pressure (boost), or charge-air oxygen concentration) to effect a change in the combustion parameter value, (3) thereafter adjusting an engine “control parameter” (e.g., commanded fuel quantity) to each cylinder to maintain a desired target for the combustion parameter value (such as 10 bar/crank angle degree, or a smaller value, such as 6 bar/crank angle degree), and (4) individually adjusting cooling, heating and/or fuel command to deviating cylinders to achieve uniform combustion.
