摘要： The amount of secondary air flowing through a bypass air passage bypassing the throttle valve of an engine, which is connected to an automatic transmission of a vehicle having an air-conditioner, is controlled by an air control valve disposed in the bypass air passage. The air control valve is controlled on the basis of the result of comparison between a signal indicative of the actual idling rotation speed of the engine detected by the distributor of the engine and a reference signal indicative of a desired idling rotation speed of the engine. The level of this reference signal indicative of the desired idling rotation speed of the engine varies depending on the on-off of the air-conditioner in the vehicle or on the position of the shift lever of the automatic transmission.

摘要： A system for controlling the amount of air taken in by an engine comprises an air duct tube bypassing a throttle valve of an intake tube for taking in air supplied to an automobile engine, a plurality of valves for regulating the amount of air passing through the air duct tube, and control device therefor. The amount of air in the bypass is controlled in accordance with the temperature and number of revolutions of the engine and the air intake pressure downstream of the throttle valve. During the idling of the engine, the air intake control system generates a signal representing the standard engine idling revolutions in accordance with the engine temperature, compares the actual engine revolutions with a reference, and regulates the amount of air flowing in the bypass by use of the results of a comparison, thus rendering the actual engine revolutions identical to the reference. During the loaded engine operation, by contrast, the amount of bypass air is so controlled that the air intake pressure downstream of the throttle valve is maintained at predetermined constant value.

摘要： An air-fuel ratio feedback control system for the internal combustion engine produces a fuel supply control signal by delaying a rich or lean signal obtained by comparing the oxygen concentration in the exhaust gas with a reference value. The turning on of an idle switch operatively connected with the engine throttle valve, a predetermined time after the turning off of the idle switch and the engine speed included in a predetermined region are detected in order to delay the rich or lean signal to rich or lean side by an optimum delay time as selected according to the engine operating conditions, thus feedback controlling the amount of fuel supply.

摘要： The combination of a fuel supply system for an internal combustion engine, an exhaust gas oxygen concentration sensor and a feedback control system including an integration circuit connected to the fuel supply system and a correction control circuit connected to the exhaust gas oxygen concentration sensor and the integration circuit. The combination controls the air-fuel mixture to be supplied to an engine in accordance with an integration output signal, which in turn is generated from the output signal generated by the exhaust gas oxygen concentration sensor. The correction control circuit serves to disconnect the exhaust gas oxygen concentration sensor from the integration circuit when a predetermined operating condition of the engine is reached, thereby holding the output from the integration circuit constant.

摘要： During starting of an engine, enrichment correction according to engine starting enrichment is executed. After starting of the engine, enrichment correction is transferred gradually with the lapse of time from starting enrichment to normal warm-up enrichment. The transfer speed from starting enrichment to normal warm-up enrichment is changed depending upon whether a throttle valve is in an idle position or not.

摘要： An air-fuel ratio feedback control system is disclosed in which a sensing output representing the oxygen concentration in the exhaust gas of an internal combustion engine is compared with a predetermined set value. The output of the comparator is integrated and the amount of fuel injection is corrected by being increased or decreased in accordance with the integration output having an increasing or decreasing polarity so as to control the air-fuel ratio at a stoichiometrical value. At the time of engine start, the air-fuel ratio feedback control is stopped, and this condition is held after engine start. Further, the holding function is cancelled by a signal representing the activation of the detection output of the oxygen sensor.
