摘要： An auxiliary flow control valve is disposed in an exhaust gas recirculation passageway at a location upstream of a main flow control valve controlling the flow rate of exhaust gases recirculated into an intake system. Two conduits communicating with an intake manifold communicate with a vacuum chamber of a servo motor controlling the main flow control valve. One of the conduits has formed therein a restriction to limit the flow rate of fluid therethrough. A check valve is disposed in the other conduit to close the same when the vacuum in the intake manifold is increased and constant and to open the other conduit when the vacuum in the intake manifold is reduced.

摘要： Disclosed is an automotive multi-cylinder internal combustion engine in which exhaust gases from one or more of the exhaust ports of the engine cylinders are partially recirculated into the mixture induction system of the engine and secondary air is injected into exhaust gases from the remaining exhaust ports under normal operating conditions of the engine. The recirculation of the exhaust gases is interrupted and furthermore secondary air is injected into the exhaust gases from all the engine cylinders under predetermined non-normal operating conditions such as idling and decelerating conditions of the engine.

摘要： An engine system of the invention comprises an internal combustion engine; a carburetor; an exhaust gas recirculation system; an exhaust gas treatment device; and a source of secondary air, in which there is provided a fluid network which interconnects the source of secondary air, the engine exhaust system at a position upstream of the exhaust gas treatment device and the exhaust gas recirculation system at a position upstream of an exhaust gas recirculation valve and there is also provided an air injection control valve fluidly disposed in the fluid network intermediate the source of secondary air and the exhaust gas recirculation system. The air injection control valve is adapted to selectively permit and prevent the admission of air to the exhaust gas recirculation system. A controller for the air injection control valve is also disclosed which comprises a detector that generates as an output signal a first signal responsive to urban driving conditions which are empirically determined to occur when the motor vehicle is driven in urban areas and a second signal responsive to rural driving conditions which are empirically determined to occur when the motor vehicle is driven in rural areas. The controller causes the air injection valve to permit the admission of air to the EGR system when the detector detects the rural driving conditions.
