Pipe.
Using the fuel oil supply system of above-mentioned patent, astatki is not suitable for, and start be not easy at low temperature.It is above-mentioned special
Oil supply system in profit, the pressure in its oil circuit is 10-20MPa；If continuing to increase charge oil pressure, although being atomized to fuel feeding
There is certain improvement, but be so that in fuel pipe that pressure is excessive, easily occurs accident so that engine reliability is low.
Utility model content
The purpose of this utility model, which is to provide, a kind of to be applied to astatki, is capable of the high hair of the reliability of cold-starting
Motivation oil supply system.
To achieve these goals, the utility model is realized in：A kind of oil supply system of engine, including with
The fuel oil box of oil-out and oil return opening, fuel filter, fuel pump and pressure regulator, the oil-out and the fuel filter
Clear device connection, the fuel filter are connected with the fuel pump, and the fuel pump is connected with the pressure regulator, the pressure
Draught control mechanism is connected with the oil return opening of the fuel oil box, and the fuel pump is also connected with engine, it is characterised in that：Described
Air-assisted atomisation injectors are provided with engine, the fuel pump passes through the air-assisted atomisation injectors and the engine
Connection.The engine fuel system set using aforesaid way, the engine that can be applied on unmanned plane, enables to nobody
Engine on machine can use astatki, such as kerosene or light diesel.In addition, can also under low-temperature condition without
Other supplementary modes start.
Further, air pump is additionally provided with, the air pump is connected with the air-assisted atomisation injectors.
In order to further improve reliability, the air pump is also connected with the pressure regulator.
Beneficial effect：
The oil supply system of engine of the present utility model, astatki, such as kerosene or light diesel can be used, and adopted
With other countershaft modes need not be increased during astatki.And started using oil supply system of the present utility model easily, even in low
It can also start easily under temperature.In addition, the oil circuit pressure of oil supply system of the present utility model is low, only 0.5-0.8MPa, carry significantly
The high reliability and safety energy of engine fuel system.
Engine fuel system of the present utility model is particularly suitable for use in small and medium size unmanned aerial vehicles, not only reliable operation, and gently
Quantization, cost are low.It need to only be transformed on original engine.
Brief description of the drawings：
Fig. 1 is the schematic diagram of engine fuel system.
Embodiment：
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings, but the utility model
These embodiments are not limited to, any improvement or replacement on the present embodiment essence spirit, still fall within the utility model
Claim scope claimed.
Embodiment：As shown in figure 1, a kind of oil supply system of engine, including the combustion with oil-out 11 and oil return opening 10
Fuel tank 1, fuel filter 2, fuel pump 3 and pressure regulator 8, the oil-out 11 are connected 2 with the fuel filter, institute
State fuel filter 2 to be connected with the fuel pump 3, the fuel pump 3 is connected with the pressure regulator 8, the pressure regulation
Device 8 is connected with the oil return opening 10 of the fuel oil box 1, and the fuel pump 3 is also connected with engine 5, is set on the engine 5
Air-assisted atomisation injectors 4 are equipped with, the fuel pump 3 is connected by the air-assisted atomisation injectors 4 with the engine 5.
In addition, being additionally provided with air pump 7, the air pump 7 is connected with the air-assisted atomisation injectors 4, and the air pump 7 also with the pressure
Draught control mechanism 8 connects.
Wherein, the fuel pump 3 is electric fuel punp.
Using the oil supply system of the engine of the present embodiment, in the presence of engine control system, electric fuel punp will
In fuel oil box and then pressurization feeds to pressure regulator and air-assisted atomisation injectors, and it is auxiliary that pressure regulator regulation feeds to air
The oil pressure of atomizer oil circuit is helped, the oil pressure of supply nozzle is kept stable, nozzle is under engine control system control action
Complete oil supply function；In addition, the air pump being connected with nozzle provides pressure-air for nozzle, the pressure-air can be in nozzle
Fuel oil carry out high-pressure atomization.
Moreover, engine fuel system of the present utility model can use astatki, such as kerosene or light diesel, and
Using other supplementary modes need not be increased during astatki.It is easy to be started using oil supply system of the present utility model, even in low
It can also start easily under temperature.In addition, the oil circuit pressure of oil supply system of the present utility model is low, only 0.7MPa, substantially increase
The reliability of engine fuel system.
