摘要： An air-fuel ratio control system for internal combustion engines has an air-fuel ratio sensor mounted in an exhaust pipe of an internal combustion engine and is adapted to produce an output indicative of the air-fuel ratio of a mixture supplied to the engine, on the basis of the composition of exhaust gases in the exhaust pipe. The air-fuel ratio sensor is provided with an electric heater for heating the air-fuel ratio sensor. The system further has an engine operation sensor adapted to sense, through detection of the state of the ignition switch, whether the engine has been stopped. When the engine operation sensor has sensed that the engine has been stopped, the electric heater is supplied with power for a predetermined time after the stop of the engine so as to evaporate any water content clinging to the air-fuel ratio sensor.

摘要： In a fuel injection system for an engine, the degree of opening of a throttle valve provided in the suction pipe is detected with a throttle valve sensor. When the load of the engine is smaller than a predetermined value, a control unit operates to close an electromagnetic valve provided in a bypass passageway of the suction pipe, thereby setting the flow rate of air in the bypass passageway to zero or an extremely small value, whereby, when the load of the engine is higher than the predetermined value, the quantities of exhaust gases of hydrocarbon and carbon monoxide are reduced, and when the engine is under a light load, the fuel consumption is reduced.

摘要： A fuel-injection control system for an internal combustion engine capable of ensuring the stable and proper backup operation of the engine in case of a failure of an intake-air sensor without suffering from any substantial influence from the amount of intake air flowing through a bypass conduit which bypasses a part of intake air in an intake passage across a throttle valve. The fuel-injection control system comprises: the intake-air sensor for detecting the flow rate or the pressure of intake air sucked into the engine; a throttle-opening sensor adapted to generate an output signal representative of the opening degree of the throttle valve; a temperature sensor adapted to generate an output signal representative of the temperature of an engine coolant; an engine RPM sensor adapted to generate an output signal representative of the RPMs of the engine; and a control unit adapted to receive output signals of the sensors for controlling the operations of the fuel injection valves on the basis of the information on engine operating conditions obtained from the sensors in a manner such that when the intake-air sensor fails, the amount of fuel to be injected from the fuel injection valves is determined on the basis of the opening degree of the throttle valve detected by the throttle-opening sensor, the temperature of the engine coolant detected by the temperature sensor, and the RPMs of the engine detected by the engine RPM sensor.
