[0002] Diesel vehicles are widely used in life, involving all walks of life. At present, there is no successful case of diesel vehicle fuel preheating, especially in autumn and winter when the temperature drops to 0°C or the diesel model is not replaced in time, the vehicle is slightly longer If the time stays and the flame is turned off, the diesel oil will thicken or even condense into a waxy body, which will block the oil circuit, filter, fuel pump and fuel injector, etc., resulting in the failure of the vehicle to start or even failure and other losses.
For this situation, people often use an external power supply to connect the electric heater and the oil tank and oil pipe for smoking and roasting with an open flame. This not only poses a serious safety hazard, but also cannot fundamentally solve the problem.
In addition, replacing the corresponding high-grade diesel oil in winter is also a solution to the problem of diesel wax hanging. However, with the continuous rise of oil prices and the impact of the country's energy-saving and emission reduction policies, as well as the tight supply of high-grade diesel in winter, the cost consumption and restrictions on car owners It is obvious
According to the average price difference of national high and low grade diesel oil, one liter of diesel is calculated at 1 yuan, and the difference is 1176.5 yuan per ton. No matter for light vehicles or heavy mining vehicles, the operating cost will increase significantly
