Electronic fuel injection control system for an internal combustion engine

摘要: An electronic fuel injection (EFI) control system (10) for an internal combustion engine. The EFI is disclosed in conjunction with a compression ignition engine (12) where the parameters of quantity (446) and timing (460) are controlled on basis plurality operating conditions. parameter obtained from comparison computed values percent load (428) full (444) lesser two being selected. has proportional component (416) that function actual speed (414) commanded (412), integral (426) related to cumulative error (422). manifold air density (436). summation quantities advance. One ( 452) selected (446). other (456) temperature (442). includes capability trim compensate variations individual injector (42) cylinder (16) characteristics.
