    摘要: A fuel control system for an internal combustion engine capable of correcting an inlet air flow rate, used for the computation of a fuel injection, in consideration of a blow-back flow rate. The inlet air flow rate is detected by a hot-wire type sensor and sampled by a control unit. The control unit determines whether or not the sampled inlet air flow rate has reversed twice its gradient from the negative one to the positive one between predetermined crank angles of the engine and computes the blow-back flow rate subtracted from the inlet air flow rate.

    摘要: In a fuel supply control method including determining a cylinder at a suction stroke in a multiple cylinder internal combustion engine at each generation of a first predetermined crank angle position signal and injecting/supplying into a cylinder at a suction stroke a first amount at fuel which is computed by a first technique based on a sucked amount of air, A, and number of engine rotations, N, representing an engine load, a method comprises determining a cylinder at a suction stroke for asynchronous injection at each generation of a second crank angle position signal which is nearer to a top dead center of each cylinder than the first predetermined crank angle position signal; detecting a throttle valve opening for each predetermined time Ts and computing a throttle value opening variation .DELTA. .circleincircle.H ; and injecting/supplying, upon determining the variation .DELTA. .circleincircle.H as being greater than a predetermined value, a second amount of fuel corresponding to the variation .DELTA. .circleincircle.H into the cylinder which has been determined by the second crank angle position signal as being at the suction stroke and into a cylinder at a corresponding exhaust stroke. By so doing, there is an increased chance of being able to correct an incremental fuel which is asynchronously injected into a cylinder at the suction stroke and cylinder at the exhaust stroke, thus ensuring an enhanced response of the vehicle to an engine output at a time of acceleration.

    摘要: A fuel controller for an internal combustion engine has a control unit which calculates the amount of fuel to be supplied to the engine by fuel injectors and drives the fuel injectors with a prescribed timing. The timing of the fuel injection is advanced at high engine speeds. The fuel injection timing is set such that the fuel injection is performed substantially in synchrony with the calculation of the amount of fuel to be supplied even when the fuel injection timing is advanced.

    摘要: A system and a method for controlling fuel supply to an internal combustion engine are disclosed in which excessive supply of fuel to the engine is effectively prevented in a most reliable manner particularly at the time of engine deceleration. To this end, a reduction in the amount of intake air sucked into an engine per intake stroke is sensed, and the amount of fuel supplied to the engine is reduced when there is a reduction in the intake air amount sucked into engine per intake stroke. The amount of reduction in the fuel supply is changed in accordance with at least one of the number of revolutions per minute of the engine and the amount of intake air sucked into the engine per intake stroke.
