ABSTRACT:
An engine measurement and control methodology wherein the engine combustion rate and IMEP are measured by measuring the in-cylinder pressure at specific crank angles and utilizing a basic reading of pressure in the combustion chamber when it will be near to atmospheric, and also at at least one point in time after ignition begins and before top dead center. The measured data can be employed for fine tuning the engine control to obtain optimum performance.
