摘要： In an air-fuel ratio control system for internal combustion engines, an electronic control unit supplies a drive signal to an air-fuel ratio actuator in response to signals from an oxygen sensor and a heavy load sensor. The electronic control unit holds the air-fuel ratio compensation signal to a predetermined value when the heavy load sensor detects that a predetermined time has not passed since the engine enters a heavy load condition, and changes the air fuel ratio compensation signal to a predetermined value associated with the rich mixture when it is detected that the predetermined time has passed.

摘要： An exhaust gas recirculation apparatus for an internal combustion engine, which has a so-called EGR (Exhaust Gas Recirculation) valve provided with a vacuum actuator for controlling the amount of exhaust gas to be recirculated. An air introducing pipe is opened to the intake system for introducing an extra amount of air into the engine. An air control valve is provided on the air introducing pipe for stopping this introduction of the extra amount of air into the engine so that a rich air-fuel mixture can be supplied into the engine when the engine is beginning to accelerate from a low rotational speed. The vacuum actuator of the EGR valve is connected to this air introducing pipe, in order to carry out an EGR operation when a rich combustible mixture is supplied to the engine.
