A fuel preheating system for diesel vehicles

Abstract

The invention discloses a fuel oil pre-heating system for a diesel type automobile, and belongs to the technical field of fuel oil pre-heating of a diesel type automobile. The fuel oil pre-heating system for the diesel type automobile can effectively realize fuel oil pre-heating and automobile low-temperature starting and operating and can lower the use cost of fuel oil. The fuel oil pre-heating system for the diesel type automobile comprises an oil supply system and a water circulation pre-heating system; the oil supply system comprises a main oil tank, an auxiliary oil tank, a two-position three-way magnetic valve, an oil outlet pipe, an oil inlet pipe and an oil return pipe, wherein the two-position three-way magnetic valve is communicated with the main oil tank, the auxiliary oil tank and the oil outlet pipe, the oil outlet pipe is communicated with the oil inlet pipe, and the oil inlet pipe and the oil return pipe pass through an automobile engine and form a loop; the water circulation pre-heating system comprises a main oil tank heating chamber, a heat exchanger, a water outlet pipe, a heating water pipe and a water return pipe, wherein the heat exchanger, the water outlet pipe, the heating water pipe and the water return pipe form a loop with a water tank of the automobile engine. The fuel oil pre-heating system is suitable for being used by various light or heavy diesel automobiles.

Description

technical field [0001] The invention specifically relates to a fuel preheating system for diesel vehicles, belonging to the technical field of fuel preheating for diesel vehicles. Background technique [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 Staying for a long time and turning off the flame will cause the diesel to thicken or even condense into a waxy body, clogging the oil circuit, filter, fuel pump and fuel injector, etc., resulting in the failure of the vehicle to start or even causing losses such as failure. For this situation, people often use an external power supply to connect the electric heater and the oil tank and the oil pipe for smoking and roasting with an open flame, which not only has serious potential safety ...

[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
