Description
Technical field
The utility model relates to a kind of fuel oil supply device of non-road vehicle, particularly a kind of fuel oil supply device that uses high trade mark diesel oil at Han Qu.
Background technique
At Han Qu, because temperature is very low, vehicle need use the diesel oil of the lower trade mark, has so just increased operating cost greatly.In order to reduce this cost, proposed to use the oil of the higher trade mark, but, the condensation of diesel oil, the situation of wax deposition will inevitably occur at the diesel oil that Han Qu uses the higher trade mark at Han Qu.Solve following two problems with regard to needs like this: 1, under the low temperature environment, the problem of the needed liquid diesel oil of engine operation; 2, behind the engine stoping operation, be unlikely to make the condensation in motor of high trade mark diesel oil, wax deposition at low temperatures, and the problem that the motor after causing for a long time can't start once more.
Summary of the invention
The purpose of this utility model provides a kind ofly uses the fuel oil supply device of high trade mark diesel oil at Han Qu, and it can normally use high trade mark oil in cold district, thereby reduces the user cost of automobile at Han Qu.
Technical solutions of the utility model are: design a kind of fuel oil supply device that uses high trade mark diesel oil at Han Qu, it is characterized in that: which comprises at least main fuel tank Preheating unit, drop tank oil supplying device, preheating diesel-oil filter and high-pressure service pump, draw two oil pipes from high-pressure service pump; Wherein an oil pipe is told two-way by first electromagnetic change-over valve, and one the tunnel is connected with main fuel tank, and another road is connected with drop tank; Another root oil pipe is told two-way by second electromagnetic change-over valve, and one the tunnel is connected with the main fuel tank Preheating unit, and another road is connected with the drop tank oil supplying device.
Described main fuel tank Preheating unit is to increase fuel tank preheating sensor unit in the main fuel tank, and the preheating diesel-oil filter is connected with fuel tank preheating sensor unit, and the preheating diesel-oil filter is connected with second electromagnetic change-over valve by the preheating oil pipe.
Described fuel tank preheating sensor unit, preheating diesel-oil filter and preheating oil pipe can both produce heat, to oily preheating insulation.
Described drop tank oil supplying device is that drop tank is connected with second electromagnetic change-over valve by motor-drive pump.
Be high trade mark diesel oil in the described main fuel tank, be low trade mark diesel oil in the drop tank.
The beneficial effects of the utility model are owing to all adopt pre-heating device at main fuel tank to the oil circuit between the high-pressure service pump, therefore to guarantee that high trade mark oil remains liquid state at low temperature environment, to engine oil.And when motor is not worked, be full of oil circuit by the low trade mark diesel oil in the drop tank, prevent the condensation in oil circuit of high trade mark diesel oil, wax deposition, thereby also guaranteed under the lower temperature environment, but the diesel oil in whole oil circuit all is in supply condition.
Description of drawings
The utility model is described in further detail below in conjunction with embodiment's accompanying drawing:
Fig. 1 is the utility model oil supply loop schematic representation.
Among the figure: 1, first electromagnetic change-over valve; 2, high-pressure service pump; 3, second electromagnetic change-over valve; 4, preheating oil pipe; 5, preheating diesel-oil filter; 6, fuel tank preheating sensor unit; 7, main fuel tank; 8, motor-drive pump; 9, drop tank.
Embodiment
As shown in Figure 1, which comprises at least main fuel tank Preheating unit, drop tank oil supplying device, preheating diesel-oil filter 5 and high-pressure service pump 2, draw two oil pipes from high-pressure service pump 2; Wherein an oil pipe is told two-way by first electromagnetic change-over valve 1, and one the road is connected in the main fuel tank 7, and another road is connected in the drop tank 9; Another root oil pipe is told two-way by second electromagnetic change-over valve 3, and one the tunnel is connected with the main fuel tank Preheating unit, and another road is connected with the drop tank oil supplying device.The main fuel tank Preheating unit is for increasing fuel tank preheating sensor unit 6 in the main fuel tank 7 that is injected with high trade mark diesel oil, preheating diesel-oil filter 5 is connected with fuel tank preheating sensor unit 6, preheating diesel-oil filter 5 is connected with second electromagnetic change-over valve 3 by preheating oil pipe 4, fuel tank preheating sensor unit 6, preheating diesel-oil filter 5 and preheating oil pipe 4 all have the preheating insulation effect, thereby have guaranteed that the high trade mark diesel oil in this section oil circuit is in liquid state.The drop tank oil supplying device is to have annotated to be connected with second electromagnetic change-over valve 3 by motor-drive pump 8 than the drop tank 9 that hangs down trade mark diesel oil.
The main fuel tank Preheating unit is constantly to the high trade mark diesel oil preheating in the main fuel tank 7 in the cold area vehicle driving, thereby makes that vehicle can cruising at cold area.
Parking with engine misses after, by controlling first electromagnetic change-over valve 1, high-pressure service pump 2 begins from drop tank 9 fuel feeding of the low trade mark diesel oil of having annotated, 7 fuel cut-offs of main fuel tank, guarantee in remaining fuel delivery loop, all to be full of low trade mark fuel oil, make that the fuel oil in the oil circuit can condensation, wax deposition.
When vehicle ignition trigger again, by first electromagnetic change-over valve 1 and second electromagnetic change-over valve 3, make drop tank 9 insert whole oil supply loop, the effect by motor-drive pump 8 begins fuel feeding, 7 fuel cut-offs of main fuel tank; And after starting, then can change first electromagnetic change-over valve 1 and second electromagnetic change-over valve 3 simultaneously, and make main fuel tank 7 insert oil supply loop again, the beginning fuel feeding, drop tank 9 is fuel cut-off then.
Therefore vehicle guarantees that high trade mark oil remains liquid state at low temperature environment owing to all adopt pre-heating device at main fuel tank 7 to the oil circuit between the high-pressure service pump 2, gives engine oil.And when motor is not worked, be full of oil circuit by the low trade mark diesel oil in the drop tank 9, prevent the condensation in oil circuit of high trade mark diesel oil, wax deposition, thereby also guaranteed under the lower temperature environment, but the diesel oil in whole oil circuit all is in supply condition.When motor ignition trigger again,, convert main fuel tank 7 fuel feeding after the startup again to, solved and under lower temperature environments, adopted high trade mark fuel oil meeting condensation, wax deposition, cause fuel delivery not smooth, the problem of vehicle launch difficulty earlier by drop tank 9 beginning fuel feeding.
