ABSTRACT:
Closed-loop control of the quantity of diesel engine exhaust gas that is recirculated to an air intake of the engine responds to a degree of deviation of a sensed air inlet rate away from a desired air inlet rate. A series of dedicated adaptive correction values are selectively updated and stored in memory in response to the degree of deviation for corresponding engine operating ranges. Proportional and integral correction for air inlet rate deviations is thereby provided to an otherwise open-loop desired EGR quantity.
