At present, high-pressure co-rail oil-fired system commonly used is that a kind of useful energy is improved fuel economy and reduced the fuel injection apparatus that discharges.As shown in Figure 1, it comprises fuel tank 10, control unit of engine 11, hand oil pump 12, high pressure oil pump 13, fine cleaner 14, high pressure oil rail 15 and oil sprayer 16.Fuel tank 10, control unit of engine 11, hand oil pump 12, high pressure oil pump 13, fine cleaner 14, high pressure oil rail 15 and oil sprayer 16 link to each other successively.The return opening of high pressure oil pump 13, high pressure oil rail 15 and oil sprayer 16 is connected with the filler opening of fuel tank 10.
Yet, on the one hand, because the high-pressure co-rail oil-fired system is very responsive to air leakage; Thereby, cause the engine start difficulty easily, even start successfully; Also will also shorten the life-span of starter motor easily for a long time, the obstruction user normally uses and the motor quality is caused harmful effect.On the other hand, because the employing of high-pressure co-rail oil-fired system is the method for manual degasification, promptly utilize hand oil pump to operate manually; Low pressure oil circuit pressure is increased, and unclamp the oil discharge screw on the fine cleaner, to realize exhaust; Thereby, not only waste time and energy, and; Can take fuel oil during exhaust out of and discharge together, be difficult to reclaim, cause the fuel oil waste.
Therefore, be necessary to provide a kind of self-bleeding oil-fired system to overcome above-mentioned defective.
The model utility content
The purpose of the utility model provides a kind of ability automatic vent, prolongs engine life and the high self-bleeding oil-fired system of stability.
To achieve these goals; The utility model provides a kind of self-bleeding oil-fired system to comprise fuel tank, control unit of engine, high pressure oil pump, fine cleaner, high pressure oil rail, oil sprayer, electrically operated fuel pump and one-way valve; Fuel tank, one-way valve, control unit of engine, high pressure oil pump, fine cleaner, high pressure oil rail and oil sprayer are connected successively, and electrically operated fuel pump is parallelly connected with one-way valve.
Preferably, the self-bleeding oil-fired system of the utility model also comprises cooling plate, and cooling plate is fixed on the control unit of engine.
Preferably, the self-bleeding oil-fired system of the utility model also comprises strainer, and strainer is installed in the oil outlet of fuel tank.
Compared with prior art, on the one hand, because the oil-fired system of the utility model adopts electrically operated fuel pump to carry out automatic vent; Thereby, not only shorten the starting time of motor, thereby prolonged the life-span of motor; And owing to be automatic vent, thereby, need be through not unclamping the oil discharge screw on the fine cleaner; When exhaust, can not cause the waste of fuel oil.On the other hand, owing to be parallel with one-way valve on the electrically operated fuel pump, thereby; When electrically operated fuel pump damaged, motor began to start and drive the gear fuel supply pump work that high pressure oil pump carries, in the inlet generation negative pressure of gear fuel supply pump; One-way valve is opened; Connect the oil circuit between fuel tank and the high pressure oil pump, thereby guaranteed the normal operation of oil-fired system, improved the stability of oil-fired system.
Through following description and combine accompanying drawing, it is more clear that the utility model will become, and these accompanying drawings are used to explain the embodiment of the utility model.
Description of drawings
Fig. 1 is the structural representation of existing oil-fired system.
Fig. 2 is the structural representation of the self-bleeding oil-fired system of the utility model.
Embodiment
With reference now to accompanying drawing, describe the embodiment of the utility model, the similar elements label is represented similar elements in the accompanying drawing.
As shown in Figure 2, the self-bleeding oil-fired system of present embodiment comprises fuel tank 20, one-way valve 21, electrically operated fuel pump 22, control unit of engine 23, high pressure oil pump 24, fine cleaner 25, high pressure oil rail 26 and oil sprayer 27.Fuel tank 20, one-way valve 21 and control unit of engine 23 are connected successively, and electrically operated fuel pump 22 is parallelly connected with one-way valve 21.The oil outlet of control unit of engine 23 links to each other with the first filler opening a of high pressure oil pump 24; The first oil outlet b of high pressure oil pump 24 links to each other with the filler opening of fine cleaner 25; The oil outlet of fine cleaner 25 links to each other with the second filler opening c of high pressure oil pump 24; The second oil outlet e of high pressure oil pump 24 links to each other with oil sprayer 27 through high pressure oil rail 26, and like this, the fuel oil in the fuel tank 20 can be ejected in the cylinder (not shown) of motor through oil sprayer 27.In addition, the return opening g of the return opening f of the return opening d of high pressure oil pump 24, high pressure oil rail 26 and oil sprayer 27 all links to each other with the filler opening of fuel tank 20.
Understandably, the self-bleeding oil-fired system of present embodiment also comprises cooling plate (not shown) and strainer (not shown), and wherein, cooling plate is fixed on the control unit of engine 23, and strainer is installed in the oil outlet place of fuel tank 20.
Particularly, when electrically operated fuel pump 22 work, the fuel oil in the fuel tank 20 is successively through strainer, electrically operated fuel pump 22 and control unit of engine 23, from the first filler opening a entering high pressure oil pump 24 of high pressure oil pump 24.Then, fuel oil gets into the fine cleaner 25 from the first oil outlet b of high pressure oil pump 24, and the fuel oil that comes out from fine cleaner 25 gets into the second oil outlet e outflow of also passing through high pressure oil pump 24 high pressure oil pump 24 from the second filler opening c of high pressure oil pump 24 again.When the pressure in the high pressure oil pump 24 rose to certain value, the pressure-limit valve (not shown) that is positioned on the high pressure oil pump 24 partially opened, and fuel oil and air then flow back in the fuel tank 20 through the return opening d of high pressure oil pump 24.The fuel oil that flows out from the second oil outlet e of high pressure oil pump 24 gets into the oil sprayers 27 through high pressure oil rail 26, and is injected in the cylinder (not shown) of motor through oil sprayer 27.And when the pressure in high pressure oil rail 26 and the oil sprayer 27 surpassed certain value, fuel oil and air can also flow back in the fuel tank 20 through the return opening f of high pressure oil rail 26 and the return opening g of oil sprayer 27.When exhaust finished, electrically operated fuel pump 22 quit work, and motor can normally start.
In addition; When electrically operated fuel pump 22 damaged, motor began to start and drive the gear fuel supply pump work that high pressure oil pump 24 carries, in the inlet generation negative pressure of gear fuel supply pump; One-way valve 21 is opened; Connect the oil circuit between fuel tank 20 and the high pressure oil pump 24, like this, engine start can be unaffected.At this moment, the user can go the service station maintenance as soon as possible with electrically operated fuel pump 22.
Can know by technique scheme, on the one hand, because the oil-fired system of the utility model adopts electrically operated fuel pump 22 to carry out automatic vent; Thereby, not only shorten the engine start time, thereby prolonged the life-span of motor; And owing to be automatic vent, thereby, need be through not unclamping the oil discharge screw on the fine cleaner; When exhaust, can not cause the waste of fuel oil.On the other hand, owing to be parallel with one-way valve 21 on the electrically operated fuel pump 22, thereby; When electrically operated fuel pump 22 damaged, motor began to start and drive the gear fuel supply pump work that high pressure oil pump 24 carries, in the inlet generation negative pressure of gear fuel supply pump; One-way valve 21 is opened; Connect the oil circuit between fuel tank 20 and the high pressure oil pump 24, thereby guaranteed the normal operation of oil-fired system, improved the stability of oil-fired system.
