    • PURPOSE:To obtain stable starting performance by setting the quantity of reference starting injection fuel allocated to the injector of a throttle valve part to a higher value when the temperature is lower. CONSTITUTION:Injectors 20 and 31 are located at an intake port part 6 and a throttle valve part 2, respectively. A means 34 calculates the reference starting injection quantity TST as the necessary quantity of fuel and a means 35 sets the rate KDISST of the reference starting injection quantity allocated to the injector 31 of the throttle valve part to be higher when the temperature is lower. According to this allocation rate KDISST quantities Tit and Tip of fuel injected from a pair of the injectors 31 and 20 are calculated by a calculating means 36 and 37, respectively and outputted by the means 38 and 29 to related injectors 31 and 20. So when fuel of almost necessary quantity is ejected from the injector 31 of the throttle valve part is ejected with the engine at a low temperature, injected fuel is made finer with the air of air stream flowing around the throttle valve 2 and atomized in an intake manifold 3 to form premixture quickly.

    • PURPOSE:To compensate for a change having occurred with the lapse of time, by renewing a previously memorized intake efficiency for an intake system by the calculated intake efficiency thereof when both the efficiencies has differed from each other, to use the renewed intake efficiency to calculate a quantity of intake air. CONSTITUTION:A by-pass 7 is provided around the throttle valve 3 of an intake system. An orifice 8 and a solenoid valve 9 for opening or closing the orifice are provided halfway in the by-pass 7. A calculation and control unit 10 calculates the intake efficiency of the intake system in terms of the difference between the value of the operating condition of an engine, which changes due to the introduction of a predetermined quantity of air when the solenoid valve 9 is opened in a prescribed range of operation of the engine, and that of the operating condition of the engine before the introduction of the air. The calculated intake efficiency is compared with a previously memorized intake efficiency. When the compared efficiencies has differed from each other, the previously memorized intake efficiency is renewed by the newly determined intake efficiency so that the renewed intake efficiency is memorized. The renewed intake efficiency is used to calculate a quantity of intake air.

    • PURPOSE:To improve a mixing characteristic of air-fuel mixture as well as to aim at the promotion of lean combustion and reduction in fuel consumption by making a partial cylinder fuel injection valve and premixed fuel injection valve take partial charge of a fuel quantity corresponding to a request air-fuel ratio for partial load driving or the like on the basis of a setting ratio. CONSTITUTION:A premixed fuel injection valve 12 is used in combination with a partial cylinder fuel injection valve 11 at a time when it is at least in a partial load driving area of an engine, whereby a fuel quantity corresponding to a request air-fuel ratio of the engine is alloted and sprayed on the basis of the setting ratio of both these valves. At this time, each fuel injection timing of these valves 11, 12 provides a phase difference in consideration of flow delay time of fuel. With this constitution, the premixed fuel injection valve 12 sprays the fuel quantity allotted at a setup position of the partial cylinder fuel injection valve 11 and an intake passage 16 at the more upstream than an intake manifold 15. This fuel is premixed with air in the intake passage 16 before reaching to an intake port of the engine, and it is distributed to each cylinder 13 of the engine together with a fuel spray out of the partial cylinder fuel injection valve 11 on an air flow in the intake passage.

    • PURPOSE:To obtain a good air-fuel-mixed state over a wide operation range in an independent, cylinder-to-cylinder injection system, in which fuel is injected in a synchronized manner with a suction stroke, by sending the injected fuel onto a combustion chamber side, taking advantage of an air flow-velocity at which no wall surface slagging is formed. CONSTITUTION:In controlling a fuel injection valve 7, which is arranged at a suction port, based on output signals from an engine speed sensor 8, a crank angle sensor 9, a cooling water temperature sensor 10, and an inlet sensor 11, a range of the air flow velocity, that is lower than a critical air flow velocity Vpc, in which no wall surface slagging takes place to an inlet pipe of an injected fuel passage, is obtained first from sine-wave-resembled air flow velocity characteristics in the vicinity of the inlet valve in the range from valve-opening to valve-closing of the inlet valve in each cylinder. Next, a valve-opening position of a fuel injection valve 7 is decided, based on an air feeding valve opening position corresponding to the air flow velocity lower than Vpc. When the range of the air flow velocity lower than Vpc varies because of a change in the engine speed, the starting time of the valve opening of the fuel injection valve 7 is varied, according to the variation of the range.
