摘要： An improved method of determining activation of an exhaust gas concentration sensor for detecting the concentration of an exhaust gas ingredient in exhaust gases from an internal combustion engine. The sensor comprises an exhaust gas ingredient-detecting element, and a heater for heating the element. An output signal from the sensor is used for air-fuel ratio feedback control of an air-fuel mixture supplied to the engine. It is determined that activation of the sensor has been completed when an output voltage from the sensor has become lower than a predetermined activation-determining reference voltage. The predetermined activation-determining reference voltage is changed depending on a time period over which the heater has been energized while the engine is in an operating condition under which the air-fuel ratio feedback control should be carried out.

摘要： A method determines a control parameter of an air/fuel ratio of an internal combustion engine having an idle rotational speed control device by which the throttle valve is opened when an electric unit such as the head light or the air conditioner is turned on during the idling of the engine. The air/fuel ratio is controlled to be leaner than a target air fuel ratio when the engine is idling, and controlled to a further leaner side when the electric unit is operating during the idling of the engine.

摘要： A fuel supply control system for an internal combustion engine. A load condition sensor detects a load condition of the engine, and an ECU increases the amount of fuel to be supplied to the engine when a predetermined high load condition of the engine is detected by the load condition sensor, and sets a delay time period from detection of the predetermined high load condition of the engine by the load condition sensor to execution of increase of the amount of fuel, according to operating conditions of the engine. A time period elapsed from the detection of the predetermined high load condition is counted. The set delay time period is corrected based on a ratio of the set delay time period to the counted time period and the load condition of the engine detected by the load condition sensor before the detection of said predetermined high load condition.

摘要： While an exhaust gas sensor having an output characteristic linear with respect to the concentration of a specific component in exhaust gases from an internal combustion engine, the opening of an automatic choke valve is controlled in response to the degree of warming-up of the engine. From the time of activation of the exhaust gas sensor to the time of completion of warming-up of the engine, the automatic choke valve and an air-fuel ratio control valve arranged in an air passage bypassing a throttle valve in an intake passage of the engine, are driven so as to achieve a desired air-fuel ratio, respectively, when the difference between the desired air-fuel ratio and actual one is larger than a predetermined value, and when the difference is smaller than the predetermined value. After completion of warming-up of the engine, the air-fuel ratio control valve is driven in response to operating conditions of the engine so as to achieve the desired air-fuel ratio.

It is determined whether the vehicle is in a predetermined starting condition, and the valve opening of the exhaust gas recirculating valve is set to a first value when the vehicle is not in the predetermined starting condition, otherwise to a second value smaller than the first value. Preferably, the determination of whether the vehicle is in the predetermined starting condition is made based on the rotational speed of the engine and the speed of the vehicle.

摘要： An air intake side secondary air supply system for an internal combustion engine is provided with an open-close valve in an air intake side secondary air supply passage which is provided in addition to an air intake side secondary air supply passage for an air/fuel ratio control. The open-close valve is opened only when an amount of the secondary air through the passage for the air/fuel ratio control is higher than a predetermined level. In addition to the provision of the open-close valve, the opening of an open-close valve or a linear type solenoid valve wich is provided in the secondary air supply passage for controlling the air/fuel ratio is reduced, so that the valve operates in a range where the linearity of the operation of the valve is good. Thus, the accuracy of the air/fuel ratio control is improved especially when the amount of the secondary air is large.

摘要： To control the quantity of fuel supplied to an I.C. engine, a sensor generates an exhaust gas component concentration signal. If the present fuel supply quantity does not exceed a reference quantity, the fuel supply is set according to engine operation parameters. If the preset quantity is greater than the reference quantity for a predetermined reference time, the fuel supply is set without regard to the signal. The reference time is changed as a function of engine temperature.

摘要： An apparatus for detecting a neutral state of a transmission gear of a vehicle detects an engine rotational speed, a vehicle speed, and a condition in which the engine output power is transmitted to the transmission gear through a clutch. The apparatus judges that the transmission gear is in the neutral state when a ratio between the engine rotational speed and the vehicle speed is in any one of predetermined ranges. The apparatus also judges that the transmission gear is in the neutral state when a variation of the ratio between the engine rotational speed and the vehicle speed within a predetermined time period is greater than a predetermined value.

摘要： An air intake side secondary air supply system for an internal combustion engine is provided with a device for restricting the amount of the secondary air flowing through an air intake side secondary air supply passage when an amount of an intake air of the engine is small. By the provision of the flow restriction device, the operating range of an open-close valve or a linear type solenoid valve which is provided for controlling the air intake side secondary air, in which range the linearity of the operation of the valve is good, can be always used. Thus, the accuracy of the air/fuel ratio control is improved especially when the amount of the intake air of the engine is small.
