    摘要： An air/fuel ratio control system is provided for use with an internal combustion engine. The system includes a first air/fuel ratio detector arranged on an upstream side of a catalytic converter so as to detect the air/fuel ratio of the engine from components of exhaust gas, a second air/fuel ratio detector arranged in the exhaust system and having a detection response speed slower than the first air/fuel ratio detector, a device for controlling the air/fuel ratio of the engine on the basis of results of a comparison between a detection value from the first air/fuel ratio detector and a predetermined first reference value, a device for effecting a correction to the control of the air/fuel ratio by the air/fuel ratio control device on the basis of results of a comparison between a detection value from the second air/fuel ratio detector and a predetermined second reference value, and a device for shifting the second reference value to a lean air/fuel ratio side in a specific operation state of the engine.

    摘要： A method of and an apparatus for controlling the air fuel ratio of an internal combustion engine by which the air fuel ratio can be controlled so that the exhaust gas purifying efficiency of a catalytic converter for purifying exhaust gas of the engine may be maximum. In the apparatus, exhaust gas of the engine is first passed through a catalytic converter and then is introduced into an oxygen concentration sensor of the .lambda. type. When the air fuel ratio is compulsorily varied, the compulsorily varied condition of the air fuel ratio such as an average of variations of the air fuel ratio (average air fuel ratio) is corrected in accordance with an output of the oxygen concentration sensor thereby to control the air fuel ratio so that the purifying efficiency of the exhaust gas purifying catalytic converter may be maximum.

    摘要： A valve operating apparatus, which transmits the rotation of the crankshaft of an automotive engine to the intake and exhaust valves to open and close the valves, can selectively vary the timing to open and close the valves and ther lifts of the valves. The valve operating apparatus includes a camshaft with low- and high-speed cams and low- and high-speed rocker arms, one of which is fixed to and the other rotatably supported on a rocker shaft. The valves can be opened and closed by the low-speed rocker arm. The other rocker arm and the rocker shaft can be engaged and disengaged by an engaging mechanism that is actuated by an actuating mechanism depending on the operating condition of the engine.
