摘要： An amount of fuel fed to an engine and determined by the rpm of the engine and a suction air flow rate is increased by a predetermined amount of fuel upon detection of acceleration. When the engine is suddenly accelerated from a low-speed operational region to enter a power zone, the above-mentioned predetermined amount of fuel is corrected based on the rpm of the engine and a quantity of change in the throttle valve opening degree.

摘要： Disclosed is a fuel control apparatus in an internal combustion engine. When the running mode the engine is changed into acceleration again from deceleration after acceleration, the fuel becomes too rich if the conventional continuous correcting factor is used. In order to properly reduce the quantity of fuel supply in that case, the number of engine revolutions is counted from a point of initiation of deceleration to a point of initiation of acceleration again to thereby calculate a proper value of the continuous correcting factor corresponding to the count, so that fuel is supplied to the internal combustion engine with a quantity corrected by the thus calculated value of the continuous correcting factor.

摘要： An air fuel ratio control apparatus, performs fuel decrease compensation during deceleration with respect to an air fuel ratio upon detection of a returning operation of a throttle valve. To avoid variations in torque which detract from a smooth ride, fuel decrease compensation is prohibited under the conditions that the opening of the throttle valve is in a full opening region and the amount of return movement of the throttle valve per unit time is equal to or less than a preset valve.

摘要： A fuel is injected based on the rpm of the engine and the suction air rate. The fuel injection amount is corrected depending on a map of fuel injection share correction coefficient prepared in advance and determined by data such as a throttle valve opening and the rpm of the engine so that amounts of fuel injected will be even at the respective cylinders. The fuel injection share correction coefficient is for correcting fuel deviation due to construction of suction passage to with the respective cylinders or for correcting fuel deviation due to arrangement of two injectors in one bore with respect to the throttle valve shaft.

摘要： An engine controlling system is operative to control injection of fuel into an engine and an ignition timing thereof in accordance with predetermined maps, respectively. Each map is at a lattice pattern showing predetermined relationship between engine speed and load value determined based on the engine speed and an engine intake air flow in terms of mass flow. When the degree of the throttle valve opening is greater than a predetermined value and the engine speed and the load value read on the maps do not fall in power zones in the maps, the engine controlling system operates to increase the fuel supply and retard the ignition timing so that the increased rate of fuel supply and the retarded ignition timing fall in the power zones in the maps to prevent occurrence of a knock.

摘要： An engine control system which controls ignition timing for, and fuel supply to, an engine by scanning a map by using as parameters a first item of data representing the number of revolutions of the engine and a second item of data representing engine load. The engine control system includes filter means for providing a third item of data by suppressing the rate of change of the second item of data. The third item of data is used in place of the second item of data for scanning the map only when the engine is in a predetermined range of operating conditions in which the rate of change of a manipulated variable of a throttle valve, the number of revolutions of the engine and the rate of change of the engine load are all less than respective predetermined values.

摘要： An air flow rate measuring device has a by-pass passage branched from a main air passage leading to an engine, and heat wires provided in the by-pass passage. The inlet of the by-pass passage is positioned at the upper end of a venturi tube disposed in the main air passage, shaped annularly, and opened to the main air passage so that the air at the inlet can be subjected to the dynamic pressure of the main air stream. The outlet of the by-pass passage also is annularly formed and opened normally to the main air stream in the main air passage. The flow rate of air sucked into the engine is measured by the heat wires subjected to air flow taken in the by-pass passage.

摘要： In an acceleration pump of a carburetor for an internal combustion engine including a cylinder and a piston reciprocatorily inserted in the cylinder, the piston is formed in its upper portion with a transverse bore for a stopper member to extend therethrough to be urged by a heat sensitive element to move in a direction at right angles to the direction of reciprocatory movement of the piston, so that additional fuel for acceleration can be supplied to the engine in a quantity which is accurately corrected to accommodate itself to changes in ambient temperature, by means of the heat sensitive element. The transverse bore is formed at its top wall and bottom wall with projections, and the stopper member is formed at its upper surface and lower surface with depressed portions, so as to enable the lengths of the downward and upward strokes of the piston to be controlled in accordance with changes in ambient temperature. Thus the acceleration pump is capable of supplying to the engine additional fuel for acceleration in a quantity which is corrected to accommodate itself for changes in ambient temperature.
