Method and apparatus for determining a parameter for normalized instantaneous heat release in an internal combustion engine |
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.
