Engine Control Methods Using Combustion Pressure Feedback 890758

Production applications of engine control systems using combustion pressure feedback are now possible due to the availability of cost-effective cylinder pressure sensors and dedicated signal processors. This paper reviews combustion pressure feedback methods for spark timing, fuel, and EGR control. Potential benefits of combustion pressure feedback include improvements in engine performance, efficiency, and compensation for manufacturing tolerances, fuel variations, and engine wear.
