    摘要: A method for operating an internal combustion engine includes determining an actual combustion heat release during ongoing engine operation, calculating an expected combustion heat release corresponding to engine operation associated with the actual combustion heat release during ongoing engine operation, determining a difference between the actual combustion heat release and the expected combustion heat release, and operating the internal combustion engine in a homogeneous-charge compression-ignition combustion mode to achieve a preferred combustion phasing during each combustion cycle in response to the difference between the actual combustion heat release and the expected combustion heat release.

    摘要: A method and system for controlling an engine includes a homogeneous charge compression ignition (HCCI) operating zone boundary module determining a first HCCI operating boundary and a fuel rate module determining a first fuel rate from an operator input. The system also includes a switch module modifying the first HCCI operating boundary to a modified boundary in response to a measured mass airflow, cam positions and the first HCCI operating boundary. The system also includes a combustion control module operating the engine in a spark ignited mode when a second fuel rate request is outside the modified boundary.

    摘要: There is provided a method to determine a combustion parameter for an internal combustion engine. The method comprises monitoring cylinder pressure and crank angle during a combustion cycle, and determining a peak cylinder pressure, a crank angle location of the peak cylinder pressure, and a cylinder pressure at a closing of an intake valve. A combustion parameter is calculated based upon the peak cylinder pressure, the cylinder pressure at the closing of the intake valve for the combustion cycle, the crank angle location of the peak cylinder pressure, the cylinder volume at the location of the peak cylinder pressure, and the cylinder volume at the closing of the intake valve for the combustion cycle. The combustion parameter correlates to an instantaneous heat release of a cylinder charge for the combustion cycle.

    摘要: Operation of an internal combustion engine selectively operative in a controlled auto-ignition combustion mode is monitored. The engine is equipped with a pressure sensing device operative to monitor in-cylinder pressure. An analog signal output from the pressure sensing device is monitored during a combustion cycle. A peak cylinder pressure and a corresponding crank angle are detected and captured during the combustion cycle. A state for a combustion parameter for the cylinder for the combustion cycle is determined based upon the peak cylinder pressure and the corresponding crank angle.
