Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is a part of the embodiment of the utility model, instead of all the embodiments.Based on the reality in the utility model
Apply example, those of ordinary skill in the art's every other embodiment obtained without making creative work, all
Belong to the range of the utility model protection.
Referring to Fig. 1, the present embodiment provides a kind of extraordinary chassis fuel oil supply system, the special type chassis fuel delivery
System includes fuel tank 6, fuel preliminary filter 5, hand oil pump 4, solenoid valve 2, Fuel Oil Cooler 1 and environment temperature sensor 7；
Wherein, above-mentioned fuel tank 6, fuel preliminary filter 5, hand oil pump 4 pass sequentially through piping connection, which passes through
Pipeline is connect with engine 3；The P mouth of above-mentioned solenoid valve 2 is connect by pipeline with engine 3, and A mouthfuls are connected by pipeline and fuel tank 6
It connects, B mouthfuls are connect by pipeline with Fuel Oil Cooler 1, which is connect by pipeline with fuel tank 6；Above-mentioned environment temperature
Sensor 7 is connect by harness with engine 3.When the solenoid valve 2 powers off, P mouthfuls communicate with its A mouthfuls；When energization, P mouthfuls with
Its B mouthfuls communicates.
Further, above-mentioned environment temperature sensor 7 is electrically connected by harness with Engine ECU；Engine ECU passes through line
Beam is electrically connected with solenoid valve 2.Environment temperature sensor 7 is according to the temperature of working environment to Engine ECU output signal, engine
ECU exports control signal to solenoid valve 2 according to the signal received, controls its on state.In addition, on above-mentioned engine 3
It is also configured with for carrying out forcing cooling fan to Fuel Oil Cooler 1.Exhaust is additionally provided with above above-mentioned fuel preliminary filter 5
Mouthful.
In use, the course of work of whole system is as follows:
Before preparing to start engine 3, it is first turned on the exhaust outlet of 5 top of fuel preliminary filter, and manipulator's oil pump
4, so that fuel oil has illustrated whole system pipeline after the exhaust outlet bleed on fuel preliminary filter 5 full of whole system pipeline
Full of fuel oil, gas has been emptied；The exhaust outlet for closing fuel preliminary filter 5 at this time, starts engine 3；When environment temperature is less than 30 DEG C
