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 exhaust gas recirculation method which controls the valve opening of an exhaust gas recirculating valve to values appropriate to operating conditions of an automotive vehicle and an internal combustion engine installed therein, to thereby regulate the amount of exhaust gas recirculated from an exhaust passage to an intake passage in the engine. 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： The invention is provided with a load detecting means for detecting the value of an electric load connected to an electric generator driven by an internal combustion engine. An idling speed-up means stepwise increases an idling speed of the engine. A control means causes the idling speed-up means to operate when the detected value of the electric load continuously remains above a predetermined value for a predetermined length of waiting time. The control means is provided with a variable setting means which variably sets the waiting time in such a manner that the larger the detected value of the electric load, the shorter the length of the waiting time.

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.
