    摘要： In a fuel discharge preventive device of a gas engine, in order to prevent high-pressure gaseous fuel remaining in a fuel distributing pipe when an engine is stopped, from leaking out of a gaseous fuel injection valve to be discharged to the open air, a fuel shut-off valve is provided in a fuel feed passage through which gaseous fuel is fed to the gaseous fuel injection valve, and a suction passage communicating with a gaseous fuel storing portion is branched off from the fuel feed passage between the gaseous fuel injection valve and the fuel shut-off valve, so that the gaseous fuel in a potion of the fuel feed passage located between the gaseous fuel injection valve and the fuel shut-off valve is stored in the gaseous fuel storing portion after the engine is stopped and hence the fuel shut-off valve is closed, while the stored fuel is purged to the engine when the engine is being operated.

    摘要： A fuel injection device is provided with a fuel injection valve for injecting fuel into a combustion chamber and an air injection valve for the injection of air into the combustion chamber. One fuel injection orifice which opens into the combustion chamber is provided correspondingly to the fuel injection valve and plural air injection orifices which open into the combustion chamber are provided correspondingly to the air injection valve. A design is made so that fuel and air injected from the fuel injection orifice and the air injection orifices come into collision with each other at a collision point. The shape, size and direction of the fuel injection orifice are specified. Likewise, the number, shape, size and direction of the air injection orifice, as well as its arrangement relative to the fuel injection orifice, are specified. A design is made so that the size of a fuel spray and that of air jets at the collision point become equal to each other. A fuel injection control device is provided with various sensors for detecting an operating condition of an engine and an electronic control unit (ECU) for controlling the fuel injection valve and the air injection valve each independently. For controlling a spray penetration distance, a spray particle diameter and a spray shape of the fuel injected from the fuel injection orifice, the ECU, on the basis of the detected operating condition of the engine, controls the fuel injection valve and also controls at least one of timing and period of air injection performed by the air injection valve.

    摘要： In a d.c. solenoid in which a thermistor having a positive temperature coefficient is connected in series with a main coil, a subcoil is connected in parallel with the series connection of the main coil and the thermistor, so that a large magnetic force can be produced at the solenoid energization starting time, and generation of heat from the thermistor can be suppressed to prevent burn-out of the main coil due to continuous current supply. Both the main coil and the subcoil, when energized alone, are capable of actuating the solenoid. The d.c. solenoid is applied to a valve in a vaporized fuel absorption system.

    摘要： Driving circuitry for an electromagnetic fuel injection valve in which the holding current value is made variable to obtain a minimum necessary holding force from the holding current according to the fuel pressure includes a solenoid for driving the fuel injection valve, a capacitor charged by a high-voltage charge control part, a switch circuit for on-off controlling a high-voltage current supplied from the capacitor to the solenoid in response to an injection command signal, and a holding current supply circuit for supplying a holding current from the power supply to the solenoid. When the holding current is supplied, a comparator circuit compares a voltage obtained by converting the value of electric current flowing through the solenoid by a resistor for detection and a voltage corresponding to a fuel pressure sensor signal, and the value of the holding current is varied according to an output signal from the comparator circuit.
