Abstract
Operation of a homogeneous charge compression ignition engine is adapted to fuel variations. A variable valve actuating system is employed to effect conditions conducive to homogeneous charge compression ignition operation. Nominal valve timing is selected and adjustments thereto are made based on deviations in combustion phasing from a desired combustion phasing. Fuel delivery timing and quantity are adjusted once valve timing authority limits are reached to achieve further combustion phasing improvement.
