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.

摘要： A method of detecting abnormality in an air-fuel ratio control system for an internal combustion engine, the air-fuel ratio control system having a proportional control valve arranged in an air supply passage for supplying secondary air therethrough to the engine and controlled in response to an output signal from an oxygen concentration sensor arranged in an exhaust system of the engine in a manner such that its valve opening varies in proportion to the magnitude of driving current supplied thereto. A circuit is provided which includes a first transistor, the proportional control valve, and a second transistor arranged in the order mentioned and serially connected with each other between a power source for supplying a predetermined voltage and ground. A value of voltage at a predetermined location in said circuit is sensed while the first and second transistors are in predetermined states of conduction and non-conduction. It is determined whether there is abnormality in the air-fuel ratio control system, on the basis of the sensed voltage value.

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： 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.
