Abstract
The invention relates to anti-icing fluid of diesel vehicle and diesel heating energy-saving device, wherein it comprises an anti-icing fluid cycle system and an oil supplying system. The invention is characterized in that: the anti-icing fluid cycle system has external heater; the oil supplying system has oil tank heater, hand-operated oil pump heater, diesel filter heater, oil tube heater and anti-icing fluid temperature alarm. The invention uses anti-icing fluid heating and electric heating methods to heat the frame, oil tube, and diesel, especially the oil tube uses tube-to-tube type to be heated, to keep the diesel in oil pump at 55-65Deg. C. Since the diesel in the oil pump has high temperature, the fuel can be fully burnt, and the discharged tail gas can avoid black smoke, and the oil consumption is reduced.
Description
Technical field
The present invention relates to a kind of motor vehicle fuel oil heater, particularly relate to a kind of heat energy that produces when mainly utilizing the diesel-oil vehicle engine operation, the antifreeze for diesel vehicle and the energy-saving environment-friendly apparatus for heating diesel that diesel oil are heated by circulation antifreeze liquid, the UTILIZATION OF VESIDUAL HEAT IN technology that belongs to the diesel-oil vehicle motor, use when being suitable for diesel-oil vehicle and travelling in the winter time, the diesel-oil vehicle that is particularly suited for domestic three northern areas of China uses when travelling in the winter time.
Background technique
When diesel-oil vehicle travels in the winter time, directly the parts list surface temperature of the oil supply system of being brushed by cold wind sharply descends, be subjected to the influence of low temperature and diesel number, the paraffin in the diesel oil can be separated out at the filter screen place, i.e. the wax deposition phenomenon, thereby cause oil circuit to stop up to make the vehicle can't cruising, because oily temperature is low excessively, it is insufficient to burn, and can cause the discharge tail gas over-emitting black exhaust again, not only influence environment, fuel consumption also sharply increases.At present, the way that people handle wax deposition has two kinds: utilize the outer thermal source of car that oil supply system is done simple outer heating, to improve the oil temperature; Dismounting fuel feeding accessory cleans, blows logical or bled off dirty diesel oil.Said method can only temporarily be dealt with problems, and can't fundamentally prevent the generation of wax deposition.China's utility model patent ZL03211011.1 number " diesel-oil vehicle diesel oil heating equipment ", provided a kind of new solution: include engine cooling and circulating system and oil supply system, be characterized in engine cooling and circulating system, being provided with water supply connector and backwater joint, be respectively arranged with heater in fuel tank in the oil supply system and the diesel-oil filter, wherein the water supply connector in the engine cooling and circulating system is connected with heater water intake in the diesel-oil filter by pipeline, heater water outlet in the diesel-oil filter is connected with heater water intake in the fuel tank by pipeline, and the heater water outlet in the fuel tank is connected with backwater joint in the engine cooling and circulating system by pipeline.Though above-mentioned solution helps to prevent the generation of wax deposition, but owing to have defective on the structure: just adopted twice mode of heating in fuel tank and diesel-oil filter, and oil feed line therebetween lacks the heat tracing measure, when weather cold, for example outdoor temperature reaches subzero 25 degree when following, behind diesel-oil filter, arrive the fuel supply line between the engine fuel injection pump, the temperature of heated diesel oil can constantly descend, thereby influence the power of diesel engine, it is still insufficient to burn, still have black smoke in the discharge tail gas, not only influence environment, fuel consumption also will increase.
