Electronic control apparatus for internal combustion engine

摘要

An electronic control apparatus for an internal combustion engine monitors suction air concentration and an engine operation condition, and applies these values to a control circuit to produce output signals to control the air-fuel mixture to be supplied to the engine. The control circuit calculates a desired mass air flow rate based on at least one parameter representing an operating condition of the engine when the throttle valve is fully closed and controls the actual mass air flow rate bring it the desired mass air flow rate.
