摘要： A method of controlling the fuel supply to an internal combustion engine at acceleration, wherein a quantity of fuel to be supplied to said engine is increased by the use of a accelerating fuel increment set in response to at least the valve opening speed of a throttle valve arranged in an intake passage of the engine. The accelerating fuel increment is set in response to a parameter value representative of engine load as well as to the valve opening speed of the throttle valve, whereby the fuel quantity is increased by an amount optimal for the engine load, to improve accelerability and emission characteristics of the engine.

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 intake side secondary air supply system for an internal combustion engine equipped with an exhaust gas recirculation (EGR) system, employing a single source of control pressure for supplying a control pressure both into an air control valve for controlling the amount of the air intake side secondary air and an EGR control valve for controlling the amount of exhaust gas recirculation. The system is provided with a delay means for delaying the transmission of a fluctuation of pressure in the pressure chamber of the air control valve to a pressure chamber of the EGR control valve, thereby preventing adverse effects on the EGR operation due to an interaction between the air intake side secondary air supply system and the EGR system.

摘要： A method of effecting feedback control of the air-fuel ratio of an air-fuel mixture being supplied to an internal combustion engine, by correcting a basic fuel supply quantity by the use of a correction coefficient variable in response to the output of an exhaust gas ingredient concentration sensor. An engine low-load operating region is defined by at least one parameter representing load on the engine. When the engine enters the low-load operating region, a value of the correction coefficient is determined in response to an output from the above sensor and also an average value of values of the correction coefficient thus determined is calculated for a predetermined time period after the engine enters the low-load operating region. A target value of the correction coefficient is calculated on the basis of the average value obtained, the target value yielding a predetermined air-fuel ratio higher than a stoichiometric mixture ratio. The value of the correction coefficient is varied after the lapse of the predetermined time period and until it becomes equal to the target value while the engine remains in the low-load operating region. The basic fuel supply quantity is corrected by the use of the value of the correction coefficient thus varied.

摘要： A method of effecting feedback control of the air-fuel ratio of an air-fuel mixture supplied to an internal combustion engine to a first predetermined value, by correcting a basic fuel supply quantity by the use of a correction coefficient variable in response to the output of an exhaust gas ingredient concentration sensor, when the engine is operating in a predetermined feedback control region. A predetermined engine low-load operating region outside the predetermined feedcback control region is defined by at least one parameter representing load on the engine. When the engine enters the predetermined low-load operating region, the correction coefficient is gradually decreased until the air-fuel ratio of the air-fuel mixture is increased to a second predetermined value leaner than the first predetermined value. When the engine enters the predetermined feedback control region from the predetermined low-load operating region, the initial value of the correction coefficient is set to the product of a value of the correction coefficient obtained immediately before the engine enters the predetermined feedback control region and a predetermined enriching coefficient, and the set initial value is gradually increased until the air-fuel ratio of the air-fuel mixture is decreased to the first predetermined value.
