    • A fuel supply apparatus is adapted to control a pump which discharges fuel from a tank to a fuel passage, thereby regulating the pressure of fuel to be supplied to an engine. The tank includes a plurality of storage chambers, in a specific one of which the pump is placed. A part of the fuel discharged to the fuel passage is returned to the specific storage chamber through a branch passage. A storage chamber other than the specific storage chamber is in communication with the branch passage through a communication passage. A jet pump is operated to transfer the fuel from the storage chamber other than the specific storage chamber to the specific storage chamber through the communication passage by the action of the fuel flowing through the branch passage. An electronic control unit (ECU) controls an electromagnetic valve disposed in the branch passage to regulate the quantity of return flow, thereby delivering the fuel in a quantity corresponding to a consumption quantity of fuel to be sequentially consumed in the engine, to the engine through the communication passage.

    • In an ignition device for an engine 1, a spark plug 14 is operated to emit sparks with respect to the fuel-air mixture, so that the fuel-air mixture is ignited. A protrusion 19 provided on a flywheel 6 mounted on a crankshaft 5 is revolved with the rotation of the crankshaft 5. A magnet pickup 21 detects the passage of the protrusion 19. When the protrusion 19 passes near the magnet pickup 21, the magnet pickup 21 outputs a detection signal, in a pulse manner, having a peak value in response to the passing speed of the protrusion. When the detection signal outputted from the magnet pickup 21 exceeds a predetermined threshold value, the electronic control unit (ECU) 18 operates to activate the spark plug 14 through an ignition coil 15 so that the ignition timing is advanced or delayed in accordance with the difference in rotational speed of the shaft 5, i.e., of the engine 1.

    • In a fuel pump control apparatus provided by the present invention, if a target fuel pressure is changed, processing is carried out to determine whether the target fuel pressure has been increased or decreased so that proper transient state control can be executed. If the target fuel pressure has been increased, a fuel pump is driven by a maximum driving signal till the pressure of fuel reaches 90% of a new higher target fuel pressure. If the target fuel pressure has been decreased, on the other hand, the fuel pump is driven by a minimum driving signal till the pressure of fuel reaches 110% of a new lower target fuel pressure. In either case, transition state control is executed thereafter to drive the fuel pump at a duty ratio determined on the basis of an injection flow rate and the target fuel pressure till a predetermined delay time lapses. After the transition state control is finished, a steady state control is restored. In the steady state control, the duty ratio is determined on the basis of the pressure of the supplied fuel and the target fuel pressure. As a result, the fuel pump control apparatus provided by the present invention is capable of well keeping up with a change in supplied fuel pressure required by the internal combustion engine while allowing the cost and the size thereof to be reduced.
    • 在本发明提供的燃料泵控制装置中,如果改变目标燃料压力,则进行处理以确定目标燃料压力是否已经增加或减少,从而可以执行适当的过渡状态控制。 如果目标燃料压力增加,则燃料泵由最大驱动信号驱动,直到燃料压力达到新的较高目标燃料压力的90%。 如果目标燃料压力降低,另一方面燃料泵由最小驱动信号驱动,直到燃料压力达到新的较低目标燃料压力的110%。 在这两种情况下,随后执行过渡状态控制,以基于喷射流量和目标燃料压力确定的占空比来驱动燃料泵直到预定的延迟时间过去。 过渡状态控制结束后,恢复稳态控制。 在稳态控制中,基于所供给的燃料的压力和目标燃料压力来确定占空比。 结果,本发明提供的燃料泵控制装置能够很好地跟上内燃机所需的供给燃料压力的变化,同时能够降低成本和尺寸。
