Abstract

A method an apparatus is provided for sensing combustion pressure preferably in variable compression ratio engines having a hydraulic actuator. A low cost hydraulic pressure sensor is placed in the hydraulic actuator of the variable compression ratio engine for sensing combustion loads applied on the crankshaft support structure. Pressure readings from the sensor are indexed to crankshaft rotational angle for correlating pressure readings from the sensor to individual engine cylinders. The sensor enables real-time closed loop engine control in spark-ignition and diesel engines, as well as in homogeneous charge compression-ignition engines.
