Abstract
The utility model relates to a diesel oil intelligent heater, wherein the heating unit heats the fueler through a correlated circuit and a correlated pipe, and the fueler is controlled by a circuit control device through the correlated circuit and the correlated pipe; the engine cooling water is used as the heat source to heat the low grade diesel oil in the low temperature with high temperature of hot source and large quantity of heat. After the engine starts, the low grade diesel oil in the main tank can rapidly rise the temperature to melt the wax to make the low grade diesel oil not generate the wax deposition, and the oil circuit can be fast converted to the main oil circuit, which replaces the high grade diesel oil with the low grade diesel oil, solves the problems that the diesel engine must use the high grade diesel oil in the low temperature, thereby greatly reducing the oil consumption of the high grade diesel oil in the high grade diesel oil, saving the fuel cost and the oil consumption of the diesel oil, meanwhile reducing the discharge of the carbon monoxide.

Description
Technical field
It is the equipment of fuel with diesel oil that the utility model relates to a kind of, under low temperature environment, still can use low grade diesel oil as diesel engine etc., and makes low grade diesel oil anti-freezing device of wax deposition not under low temperature environment.
Background technique
The vast northern area of China, in the winter time, be that the automobile, tractor, engineering machinery, generator of power or other are powered device with the diesel engine with the diesel engine, according to regional ambient temperature, diesel engine generally uses-35# diesel oil ,-20# diesel oil and-high grade diesel oil such as 10# diesel oil, because under low temperature, low grade diesel oil wax deposition is stopped up oil pipe line, filter can't use; Because oil refining cost difference, low grade diesel oil is lower than high grade diesel oil price, and since the per unit volume calorific value of low grade diesel oil greater than the per unit volume calorific value of high grade diesel oil, under conditions such as equal wind speed, road conditions, same chassis uses the fuel consumption per hundred kilometers of 0# diesel oil less than the fuel consumption per hundred kilometers of using other trade mark diesel oil, therefore low grade diesel oil also can be used under cold snap, patent documentation discloses following several method:
1. chemical additives method: in low grade diesel oil, add anticoagulant by a certain percentage, solidify (wax deposition) temperature with what reduce diesel oil, but using effect is unsatisfactory, as in 0# diesel oil, adding anticoagulant, being higher than-5 ℃ still can use, particularly be lower than under-8 ℃ the ambient temperature but be lower than-5 ℃, 0# diesel oil begins wax deposition again, and oil pipe is blocked, can't use at all, and use also very inconveniently, particularly the diesel car driver under the condition, does not have metering equipment in the open air, be difficult to grasp the correct proportions of diesel oil and anticoagulant, and anticoagulant costs an arm and a leg, and about 30,000 yuan/ton, can't satisfy the client and once invest the lifelong requirement that is benefited.
2. heating means: mainly contain following three kinds:
(1), electric heating: with the automobile storage battery is power supply, with the resistance wire is heater element, fuel oil supply system parts such as oil pipe, filter, fuel tank are heated, this method has the following disadvantages, once being storage battery power shortage in winter itself,, certainly will make storage battery power shortage more if before automobile starting, diesel oil is heated with regard to electricity with storage battery, and in the winter time, automobile just was difficult to start originally; The 2nd, can not obtain a lot of heats; The 3rd, can not the diesel oil in the parts such as high-pressure service pump, oil sprayer be heated, even have only place's diesel oil wax deposition, oil circuit stops up in the same old way, diesel engine still can't start; The 4th, damage bigger to storage battery; The 5th, ad initio all to heat diesel oil all the time with electric energy, make generator be in generating state for a long time, therefore more or less increased engine load, increased diesel-fuel consumption.
(2), adopt the engine cooling water heating: because when engine start, the water in the water tank is consistent with ambient temperature, diesel oil this moment wax deposition does not have hot water that it is heated again, so low grade diesel oil wax deposition obstruction oil circuit causes diesel engine to start.
(3), heat with motor exhaust: adopt each one of major and minor fuel tank, inject high and low label diesel oil respectively, have following shortcoming: the one, the switching of major and minor oil circuit the automatic switchover of realization, the driver need be stopped to get off and be moved manually operated valve switching oil circuit, and observe main fuel tank oil temperature constantly, increase burden to the driver; The 2nd, there is not heating control function automatically, as long as motor one starting, motor exhaust just heats diesel oil always, cause that easily diesel fuel temperature is too high, particularly when the diesel oil in the fuel tank remains little, the easier diesel fuel temperature that causes is too high, makes to be full of diesel vapor in the diesel fuel tanks, causes extremely serious consequences such as diesel fuel tanks blast.
