摘要： PROBLEM TO BE SOLVED: To prevent unburned fuel from being discharged into the air after a gaseous fuel injection valve is closed, by providing a fuel shut valve in a fuel supply passage connected to the gaseous fuel injection valve and by storing gaseous fuel in the fuel supply passage in a gaseous fuel storing portion when the fuel shut valve is closed and by purging the stored fuel into an engine when the fuel shut valve is opened. SOLUTION: When an engine is operated, a fuel shut valve 6 and a gaseous fuel injection valve 8 are made open by a command from a control unit 25 and injected fuel is mixed with air and is supplied to an engine 3. A canister 13 is purged via a check valve 24 which is opened by the action of negative pressure under predetermined pressure. Then, when an operation is stopped and the valves 6, 8 are closed, a first open/close valve 20 is opened and a second open/close valve 22 is closed and the gaseous fuel remaining in a fuel distributing pipe 4 and a fuel supply passage 2a which are disposed between the valves 6 and 8 is introduced into the suction room 17 of the canister 13 via a suction passage 19 and is adsorbed by an adsorbent 14. The adsorbed fuel is purged into the engine 3 when the engine is started.

摘要： PROBLEM TO BE SOLVED: To mix gas fuel satisfactorily with intake air so as to improve combustion efficiency by providing a turning flow generating element for imparting turning flow to injected gas fuel such as LPG, between an injection nozzle and the outlet of a jet passage in the structure with the jet passage formed at the internal wall of an intake passage. SOLUTION: The upper reaches of an intake passage 2 formed of an intake pipe is communicated with a surge tank 1, and the lower reaches is communicated with a combustion chamber 4. A gas fuel jet passage 5 branching off from the intake passage 2 is provided with a gas fuel injection device 6. This injection device 6 controls the opening/closing of a ball valve by controlling current application to a solenoid so as to inject gas fuel, flowing at high pressure into a fuel passage of a fuel delivery pipe 8, from an injection nozzle 14. In this case, a turning flow generating element 15 for imparting turning flow to gas fuel injected from the nozzle 14 is fittingly installed at the outlet end of the nozzle 14 and in a passage of a fit-in pipe 9. The gas fuel is thereby mixed satisfactorily with intake air.

摘要： PURPOSE:To ensure a large amount of evaporated fuel flow while providing a compact switch valve by heating and extending a spring made of shape memory alloy in oil supply to constitute a valve body for opening operation and convert the expansion amount of spring to the opening and closing amount of valve body. CONSTITUTION:When a door of a oil supply pocket is opened in the oil supply, a switch 18 is turned on to heat an exothermic body 35. Thus, a spring 32 made of shape memory alloy is heated and extended to open a valve body 28 against an ordinary spring 34. Thus, evaporated fuel in a fuel tank 1 flows to an evaporated fuel conducting path 5 through an in-flow hole 24, a conducting port 2, a switching port 25, a valve chamber 27 and an outflow port 26. On the other hand, when the door is closed after the oil supply, the switch 18 is turned off to interrupt current to the exothermic body 35. Thus, the spring 32 made of the shape memory alloy returns the temperature to room temperature and contracts, so that the valve body 28 closes a valve with an energizing force of the ordinary spring 34 and thus the evaporated fuel in the fuel tank 1 does not flow into a path 5.

摘要： PURPOSE:To relax the restriction to installation of an evaporated fuel introduction device by providing such an arrangement that a valve element in a shut-off valve disposed in an evaporative fuel introduction passage may be opened and closed in association with the rotation of a motor which may be of a small size, thereby it is possible to miniaturize the shut-off valve. CONSTITUTION:When a door for a fuel pocket is opened during fueling, movable contacts 18a, 18b in a change-over switch 18 fall down to positions as indicated by the solid lines so that a motor 33 is normally rotated while a valve element 29 is normally rotated so as to abut against a stopper 32, and therefore, an opening and closing hole 25 is fully opened. As a result evaporative fuel in a fuel tank 1 is introduced into an absorbing device through an introduction passage 5. Meanwhile, after fueling, when the door is closed, the movable contacts 18a, 18b fall down to positions as indicated by the chain lines so that the motor 32 is reversed while the valve element 29 is reversed to abut against a stopper 31, and therefore the opening and closing hole 25 is fully closed. As a result, evaporative fuel in the fuel tank is prevented from being led out. With this arrangement it is possible to use a small size motor 33, thereby it is possible to miniaturize the shut-off valve.

摘要： PROBLEM TO BE SOLVED: To prevent a fuel transfer flow rate of a fuel pump from dropping below an allowable range when a motor for the fuel pump is operated in low voltage. SOLUTION: A controller to control the motor for the fuel pump includes a voltage applying unit 43 capable of applying a high voltage or low voltage to the motor 20 for the fuel pump, and a voltage switching ECU which outputs a voltage switching signal to the voltage applying unit 43 so that a high voltage is applied temporarily to the motor 20 for the fuel pump at predetermined timing when the motor 20 for the fuel pump operates at a low voltage. The high voltage is determined to be a voltage causing electric discharge between a commutator and a brush to destroy an electric resistance film generated between the commutator and the brush by a discharge energy, thus suppresses the growth of the electric resistance film.
