摘要： An internal combustion engine employs exhaust gas recompression and fuel injection during the recompression as part of an overall homogeneous charge compression ignition control. In-cylinder fuel reformation is estimated using exhaust gas burned gas fractions determined from sensed exhaust gases and models. Models include air actually consumed in in-cylinder fuel combustion and reforming processes and air required to complete in-cylinder combustion reactions of reformed fuel. Reformed fuel is calculated based on the modeled and measured exhaust gas burned gas fractions.

摘要： Part load operating point for a controlled auto-ignition four-stroke internal combustion engine is reduced without compromising combustion stability through negative valve overlap control operative to retain and compress combusted gases within the combustion chamber into which fuel is introduced. Combustion chamber pressures and temperatures are increased as engine load decreases. Various split-injection fuel controls are implemented during low and intermediate part load operation whereas a single-injection fuel control is implemented during high part load operation. Split-injections are characterized by lean fuel/air ratios and single-injections are characterized by either lean or stoichiometric fuel/air ratios. Controlled autoignition is thereby enabled through an extended range of engine loads while maintaining acceptable combustion stability and emissions.

摘要： A method to control combustion in an HCCI engine, to mitigate effects of combustion chamber deposits is detailed. The method comprises applying a specific surface coating to a combustion chamber surface. The surface coating has thermal properties substantially similar to the combustion chamber deposits. The thermal properties preferably include a) thermal conductivity, b) heat capacity, and c) thermal diffusivity. Applying a surface coating results in a reduction of combustion variability due to variation in combustion chamber deposits, and an improvement on combustion stability at low loads due to reduced heat loss. A preferred thermally insulating surface coating includes thermal parameters of a heat capacity in a range of 0.03×106 J/m3-K to 2.0×106 J/m3-K; a thermal conductivity in a range of 0.25 W/m-K to 2.5 W/m-K; and, a thermal diffusivity in a range of 1×10−7 m2/s to 8×10−6 m2/s.

摘要： A method and apparatus for controlling engine operation to compensate for effects of combustion chamber deposits (CCDs) on combustion in a controlled auto-ignition engine is presented. Control methodologies comprise operation of variable valve actuation, fuel injection, spark timing, and intake air and coolant temperature to dynamically compensate for the effect of CCDs. A sensitivity to core gas temperature and chamber wall thermal conditions is shown, which is correlatable to in-cylinder CCD formation. Intake charge or coolant temperature control can be used to compensate for CCD effects. An engine control scheme relies upon a parametric input that quantifies instantaneous CCD formation in the combustion chamber. The result is further applicable to control pre-ignition in a conventional spark-ignition engine.

摘要： 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.
