    摘要: A secondary air intake system for adding air to the intake of an internal combustion engine includes an air control valve for changing the open area of a secondary air intake passage. The air control valve is opened and closed from a first and second pressure supply means. A first pressure supply means gradually supplies the first and second control pressure to operate the air control valve and open and close the secondary air intake passage in response to an air-fuel ratio signal. The first pressure supply means also supplies the second control pressure independent of the air-fuel ratio signal during a predetermined engine operating state. A second pressure supply means supplies the second control pressure separately of the first pressure supply means during a predetermined engine operating state.

    摘要: An air-fuel ratio control method for an internal combustion engine. The air-fuel ratio of an air-fuel mixture supplied to the engine is feedback-controlled to a desired air-fuel ratio depending on operating conditions of the engine in response to output from an exhaust gas ingredient concentration sensor. The desired air-fuel ratio is settable to a value leaner than a stoichiometric air-fuel ratio when the temperature of the engine is above a predetermined reference value. The method comprises the steps of detecting a reduction ratio to which the transmission has been set, and changing the predetermined reference value of the temperature of the engine depending on the detected reduction ratio. The predetermined reference value of the temperature of the engine is set to a lower value as the reduction ratio of the transmission is smaller.

    摘要: According to an air-fuel ratio control method, an amount of fuel supplied to an internal combustion engine is calculated by the use of an air-fuel ratio correction coefficient set according to an output from an exhaust gas ingredient concentration sensor. An average value of the air-fuel ratio correction coefficient is calculated. When a difference between an actual value of opening of an exhaust gas recirculation control valve and a desired value of same set in response to operating conditions of the engine is larger than a predetermined value, the calculation of the average value of the air-fuel ratio correction coefficient is inhibited, or alternatively, an averaging rate in the calculation of the average value is decreased.

    摘要: A fuel supply control system for an internal combustion engine having a throttle body, and a fuel injection valve arranged in an intake manifold upstream of the throttle body for supplying fuel to all cylinders. An air throttle valve has a valve body having a notched opening formed therein and disposed to be opposite the nozzle of the fuel injection valve to increase the flow speed of intake air in the vicinity of the nozzle when the air throttle valve is fully closed. An electronic control unit controls the fuel injection valve in response to operating conditions of the engine. The electronic control unit causes the air throttle valve to be fully closed when a predetermined low rotation-speed operating condition of the engine, in which at least the rotational speed of the engine is lower than a predetermined value, is satisfied. The predetermined value of the rotational speed of the engine is set such that the lower the atmospheric pressure the smaller the predetermined value.

    摘要: A method of feedback-controlling the air-fuel ratio of a mixture supplied to an internal combustion engine to a desired air-fuel ratio which is set to a value leaner than a stoichiometric air-fuel ratio, by the use of output from an exhaust gas ingredient concentration sensor, depending upon operating conditions of the engine, the desired air-fuel ratio being set to a leaner value as the transmission of the engine is set to a smaller reduction ratio. A reduction ratio to which the transmission has been set is detected. The travelling speed of a vehicle on which the engine is installed is detected. The desired air-fuel ratio is set to a richer value as the travelling speed of the vehicle is lower, insofar as the transmission is set to the same reduction ratio.

    摘要: A fuel supply control system for an internal combustion engine comprises deceleration detecting device for detecting a predetermined decelerating condition of the engine, and fuel supply decreasing device for decreasing the supply of fuel to the engine when the predetermined decelerating condition is detected by the deceleration detecting device. A first counting device starts to count a first predetermined time period when the high-load detecting device detects that the engine has left the predetermined high-load condition. An inhibiting device inhibits the fuel supply decreasing device from operating when the deceleration detecting device detects the predetermined decelerating condition of the engine before the first counting device completes counting the first predetermined time period. A second counting device counts a second predetermined time period while the high-load detecting device is detecting the predetermined high-load condition of the engine. The first counting device starts to count the first predetermined time period when the second counting device has completed counting the second predetermined time period. An intake air increasing device increases the amount of intake air supplied to the engine while the inhibiting device is operating.

    摘要: An air-fuel ratio control system for an internal combustion engine having a carburetor with a slow speed circuit, includes a feedback control means by which an air intake side secondary air is supplied to the carburetor, on the downstream side of the throttle valve, in response to a result of detection of air-fuel ratio in terms of the oxygen concentration in the exhaust gas of the engine. Under a predetermined operating condition of the engine, the feedback control of the air-fuel ratio by means of the control of the air intake side secondary air is performed while the supply of the fuel through the slow speed circuit of the fuel supply system is controlled in response to the result of the detection of the air-fuel ratio. In a variation of the system, the supply of the fuel through the slow speed circuit is stopped during the predetermined operating condition of the engine.
