摘要： The invention comprises an engine system that is selectively operative in an auto-ignition combustion mode. A control module monitors engine operating states and control engine operation. A control subsystem controls engine operation based upon the monitored engine operating states. The control subsystem operates the engine in the auto-ignition combustion mode, and determines an effective temperature of the cylinder structure of the internal combustion engine based upon the engine operating conditions. An engine operating point is determined. A feed-forward control scheme is executed based upon the effective temperature of the cylinder structure and the engine operating point. The effective temperature of the cylinder structure is determined by monitoring engine power for an elapsed period of time.

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： A method to dynamically determine a parametric value for combustion chamber deposits (CCD), e.g. in a controlled auto-ignition engine, including in-situ evaluation of thickness of CCD, based on a sensor which monitors combustion in a homogeneous charge compression ignition engine. It includes a temperature sensor operative to monitor the combustion chamber, and a CCD parameter that is based upon a peak combustion temperature measured at a crank angle. A CCD parameter can also be determined utilizing an in-cylinder pressure monitor, wherein a combustion chamber deposit parameter is based upon crank angle location of a peak in-cylinder pressure parameter.
