Diesel-type automobile fuel oil preheating device

Abstract

The invention discloses a diesel-type automobile fuel oil preheating device, belonging to the technical field of diesel-type automobile fuel oil preheating. The invention aims to provide the diesel-type automobile fuel oil preheating device which can effectively solve the problems of fuel oil preheating and automobile low-temperature starting, and can lower the fuel oil use cost. The diesel-type automobile fuel oil preheating device comprises a diesel-type automobile main fuel tank, and further comprises a heating fuel oil tank, heat exchangers, a fuel-outlet three-way solenoid valve and a fuel-return three-way solenoid valve, wherein the fuel-outlet three-way solenoid valve is communicated with a heating fuel oil tank fuel outlet pipe and a diesel-type automobile main fuel tank fuel outlet pipe and is connected to a diesel-type automobile main fuel outlet pipe; the fuel-return three-way solenoid valve is communicated with a heating fuel oil tank fuel-return pipe and a diesel-type automobile main fuel tank fuel-return pipe and is connected to a diesel-type automobile main fuel-return pipe; one heat exchanger is arranged in the diesel-type automobile main fuel tank; and the heat exchangers are communicated with a diesel-type automobile water tank through water conveying pipelines. The diesel-type automobile fuel oil preheating device is applicable to use on various diesel-type automobiles.

Description

technical field [0001] The invention specifically relates to a fuel preheating device for diesel-type automobiles, belonging to the technical field of fuel preheating for diesel-type automobiles. Background technique [0002] Diesel vehicles are widely used in daily life, involving all walks of life. At present, there is no successful case of diesel vehicle fuel preheating. 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 failure and other losses. 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 hazards, but also cannot fundamentally solve the problem. In addition, replacing the corresponding high-grade diesel oil in w...

[0002] Diesel vehicles are widely used in daily life, involving all walks of life. At present, there is no successful case of diesel vehicle fuel preheating. 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., causing the vehicle to fail to start or even cause damage such as failure

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

Calculated according to the price difference between high and low grade diesel oil, one liter of diesel oil is calculated at 0.5 yuan, and the difference is 588 yuan per ton. Whether it is a light vehicle or a heavy mining vehicle, the operating cost will increase significantly
