Abstract:

Schematically disclosed is an engine control apparatus wherein cylinder pressure is sensed before and after the top dead center position. Desired cylinder pressure curves are stored in a microcomputer for a range of engine speed-load combinations. By electrically comparing the actual pressure-time curve with the desired pressure curve for the existing speed-load combination it should be possible to generate an error signal representing deviation of actual engine performance from the desired performance, i.e., a permissible plus or minus band following the desired curve. The invention would provide a control action using only three parameters, namely engine speed, engine load and cylinder pressure. Author
