Technical field
The present invention relates to a kind of fuel supply devices, and in particular to the fuel oil of a kind of integrated mechanical three-way valve and heating function
Feedway.
Background technology
In Xinjiang, Tibet, Inner Mongol and the Northeast of China, winter temperature on average is at -10 DEG C~-30 DEG C or so, therefore
Diesel-engine road vehicle winter will be unable to using low-grade diesel in this area, because environment temperature is too low, low-grade diesel will appear
Retrogradation, wax deposition return and fuel screen, oil pipe blocking phenomenon occur, the event such as flame-out suddenly in causing vehicle that can not start or travel
Barrier.If using high grade diesel oil, not only oil price increases, and fuel consumption can also increase, so as to increase user's vehicle use cost.
At present, to realize above-mentioned regional use in winter low-grade diesel, vehicle is arranged using double fuel tanks, a fuel tank filling
High grade diesel oil is used for vehicle launch, another fuel tank filling low-grade diesel is used to use halfway.Low grade fuel tank uses
Heat treatment realizes that winter low-grade diesel use in the process will not retrogradation, wax deposition.Heating type mainly has：Electrical heating is started
Tail gas heats and coolant heating.For electrical heating pattern there are security risk, cost is preferable；Tail gas can corrode oil in tail gas heating
Case and influence beauty；Coolant heating is easy to implement, and can make full use of engine coolant heated fuel oil case, and cost is relatively low,
