Therefore, an oil tank has various functions, the oil tank not only facilitates the driving personnel, but also saves the expense of fuel oil cost; meanwhile, the driving personnel utilizes the low grade diesel perennially, the multifunctional combination oil tank has great significance on various aspects such as abrasion remission of coupling components of the motor, and intensify the automobile power and emission of tail gas.

Description

A kind of motor vehicle diesel heating and the multi-functional combination fuel tank of cold post-start

Affiliated technical field:

The utility model relates to a kind of multi-functional combination fuel tank that solves the diesel car cold-starting and prevent the fuel oil wax deposition.

Background technology:

In recent years, China's diesel-powered vehicle development is very fast, because diesel-powered vehicle is lower, economical and practical than gasoline car oil consumption, environmental-protecting performance is good again, so extremely the customer welcomes.From international automobile industrial development trend; diesel car will become the leading of automobile industry development, and still, the fuel oil of diesel-powered vehicle is subjected to the low temperature effect usually can wax deposition; make automobile be difficult to starting; can't move, bring a lot of inconvenience, trouble, add to the user; be in price difference between high trade mark diesel oil and the low trade mark diesel oil; in general, the diesel oil price differential per kilogram of different labels does not wait in 0.2-0.8 unit, the cost of commerial vehicle will be increased 10%-30% so virtually.Therefore, solve the technical matters of the low trade mark diesel oil of automobile winter operation, all significant to society, entity and individual.At present, its structure of fuel tank of all kinds of diesel-powered vehicle configurations is nearly all to be made up of an oil storage casing, an oil outlet pipe, an oil return pipe and four main portions such as oil level induction installation, function only is in order to give engine oil and oil return, and its limitation is: the diesel oil that can only lay in a kind of trade mark.Defective is: when automobile was in low temperature environment, this class fuel tank can't solve the problem of low trade mark diesel oil wax deposition and engine starting difficulty.

Summary of the invention:

Single in order to overcome existing automotive oil tank deposit fuel oil, and can't solve problem such as low trade mark diesel oil wax deposition and cold post-start difficulty in the fuel tank, the utility model provides a kind of motor vehicle diesel heating and the multi-functional combination fuel tank of cold post-start, this combination fuel tank is designed to an oil box main oil tank and additional fuel tank two zones dexterously, guaranteeing the former basic function of fuel tank---under fuel feeding and the oil return unmodified prerequisite, can not only solve the technical matters of diesel-powered vehicle cold post-start difficulty effectively, and behind engine starting, can be along with the continuous rising of cooling circulation liquid temp, progressively melt the wax of surplus in the diesel fuel tanks, to guarantee the low trade mark diesel oil of No. 0 grade of diesel-powered vehicle winter operation.

The technical scheme that its technical matters that solves the utility model adopts is: is two zones with an integral tank with the dividing plate sealed separation, be main oil tank district and additional fuel tank district, main oil tank district deposit hangs down trade mark diesel oil, mainly use for the driving engine operation, the additional fuel tank district lays in high trade mark diesel oil, mainly uses for a period of time before and after the engine low-temperature starting-up.The fuel oil of the fuel-displaced and return oil system of major and minor fuel tank switches, respectively by two go out, oil return extension pipe and two go out, oil return place tee ball valve is finished.The heating of low trade mark diesel oil in the main oil tank is to realize fuel oil is progressively heated by the cooling circulation liquid of introducing after heating up, and keeps certain temperature.In the winter of severe cold, before diesel-powered vehicle is flame-out, earlier the oil feed line with driving engine switches to additional fuel tank, and after treating all to be full of high trade mark diesel oil in the driving engine oil return feeding systems such as oil line, fuel transfer pump, fil, high-pressure oil pump of vehicle, the oil return line with driving engine switches to additional fuel tank again; When diesel-powered vehicle carries out cold post-start, high trade mark diesel oil with additional fuel tank carries out cold start earlier, and when fuel oil temperature reached more than 5 ℃, the wax of low trade mark diesel oil began comprehensive thawing in the main oil tank, afterwards, respectively confession, the oil return line of driving engine switched to main oil tank again.

The beneficial effects of the utility model are: switch by the fuel oil in the major-minor fuel tank, utilize the high trade mark diesel oil in the additional fuel tank to solve engine low-temperature starting-up, then, melt low trade mark fuel oil in the main oil tank by the cooling circulation liquid temp comprehensively, realize that low temperature environment uses the purpose of No. 0 low trade mark diesel oil such as grade down.A kind of fuel tank has multiple function, has both made things convenient for navigating mate, has saved the fuel cost spending again, simultaneously, uses low trade mark diesel oil throughout the year, to alleviating the wearing and tearing of driving engine male part, strengthen automobile power, and all many-sides such as exhaust emissions, all significant.
