摘要： A method of controlling the supply of fuel to an internal combustion engine having first and second fuel injection valves arranged in the intake passage downstream and upstream of the throttle valve, respectively, both being upstream of the intake manifold wherein the first and second fuel injection valves are selectively operated to supply fuel to the cylinders in dependence on operating conditions of the engine. Fuel is supplied to a plurality of cylinders of the engine through the first fuel injection valve alone when the engine is operating in a predetermined low load condition. In a middle/high load middle speed region of the engine, a substantially constant minimum required quantity of fuel is supplied through the first fuel injection valve, and simultaneously a quantity of fuel appropriate to the middle/high load middle speed region is supplied through the second fuel injection valve. In a high load high speed region of the engine, if a time interval of generation of a signal generated at predetermined crank angles of the engine is longer than the fuel injection period of the second fuel injection valve, a quantity of fuel corresponding to a difference therebetween is supplied through the first fuel injection valve and simultaneously a quantity of fuel corresponding to the time interval is supplied through the second fuel injection valve.

摘要： A method of controlling the air-fuel ratio of a mixture of fuel supplied to an internal combustion engine. Feedback control is effected to response to an output from an exhaust-gas concentration sensor to bring the air-fuel ratio to a predetermined value when the engine is in a predetermined medium-load operating region. It is determined whether or not the engine is in a predetermined high-load operating region in which the feedback control is interrupted for bringing the air-fuel ratio to a value smaller than the predetermined value, and whether or not the engine is in a predetermined low-load operating region in which the feedback control is interrupted for bringing the air-fuel ratio to a value larger than the predetermined value. The feedback control is effected even when the engine is in the predetermined low-load operating region, if the engine continually stayed over a first predetermined time period in the predetermined high-load operating region, and has shifted to the low-load operating region within a second predetermined time period after leaving the predetermined high-load operating region.

摘要： An idling speed feedback control method for an internal combustion engine for controlling the operating amount of a control valve for regulating the quantity of intake air being supplied to the engine in response to the difference between a desired idling speed and an actual engine speed, while the engine is in a predetermined idling region. A correction value for the operating amount of the control valve is determined in dependence upon the valve of a signal indicative of generating conditions of a generator driven by the engine for supplying electric power to at least one electrical device, and the operating amount of the control valve is corrected by means of the thus determined correction value. When the engine has entered the predetermined idling region immediately following deceleration, an initial value of the operating amount of the control valve which is applied at the start of the feedback control is set to a sum of a value obtained by correcting the correction value by means of a predetermined increment, and a predetermined reference value. While the engine is decelerating toward the predetermined idling region, the operating amount of the control valve is set to a value equal to the initial value.

摘要： A method for detecting an irregularity in the valve-timing changeover in an engine having a valve operating mechanism capable of operating the intake valves or exhaust valves, or both, in a different manner, known as valve timing, such as the magnitude of valve lift or the duration the valve remains open, for improving the operation of the engine at different engine speeds. The method compares the oil pressure in the supply passage to the valve timing changeover mechanism with the oil pressure that should exist after the changeover caused by the latest instruction to determine an irregularity if the pressures are not equal. A time delay may be used to accommodate the inherent time lay in the changeover to avoid a premature determination of an irregularity. An alarm may be energized or a fail-safe procedure initiated when an irregularity is detected.
