Detailed description of the invention
The abluent of the present invention is a kind of abluent, and it makes an addition to this fuel to accompanying attachment in the fuel injection system of the nozzle spraying this fuel to remove the fuel-supplying unit from supply fuel.This abluent is preferred for vehicle, is more preferably used for being equipped with the vehicle of Diesel engine.It should be noted that, than vehicles, this abluent can also be used for building machinery, fishing boat, electromotor, burning fuel thus add heating furnace or the boiler etc. of hot fluid.Hereinafter the situation of the vehicle for being equipped with Diesel engine is illustrated.
Diesel engine uses light oil as fuel.Therefore, the abluent of the present invention adds with the ratio of regulation relative to light oil.First, with reference to Fig. 1, simply the fuel injection system of the vehicle being equipped with Diesel engine is illustrated.Fuel injection system refer to from as fuel-supplying unit supply pump 10 to as injection fuel nozzle ejector 11 the system by fuel, containing fuel feed pipe 12, common rail 13.Therefore, the fuel supply mode shown in Fig. 1 is joint-track type.
Pressure transducer 14 is installed in common rail 13, and connects reflux pipe 16a via pressure-control valve 15.It addition, supply pump 10 is connected with reflux pipe 16b, ejector 11 is connected with reflux pipe 16c.Herein, although illustrate as joint-track type, but the abluent of the present invention also apply be applicable to above-mentioned unit injector formula or uses in upright arrangement type ejector pump, distribution type ejector pump, the fuel injection manner of self reliance type ejector pump.
Also show that the fuel tank 17 beyond fuel injection system and fuel filter 18 in FIG.In fuel tank 17, although not shown, but can possess prefilter.It addition, also show that control unit 19 in FIG, described control unit 19 by the holding wire represented in dash-dot line, receives and comes from the signal of the pressure transducer 14 of pressure in detection common rail 13, ejector 11 is sent instruction, in order to control fuel injection amount.
Being added to fuel tank 17 by light oil as fuel, the supply pump 10 started by the starting with Diesel engine is aspirated via fuel filter 18.After supply pump 10 boosts to the pressure of regulation, supply to common rail 13 via fuel feed pipe 12.Ejector 11 has the fore-end of needle-like, possesses pin and the solenoid of the position being fixed on blocking fuel orifice, is adjusted the rise time (lift of pin by solenoid
Time), in combustor, fuel is sprayed from there through spray-hole.It should be noted that, before starting to spray fuel from ejector 11, the fuel automatically supplying pump 10 in the future refluxes to fuel tank 17 via reflux pipe 16b.
