Fuel tank heating structure

Abstract

The invention discloses a fuel tank heating structure with a good heating effect. The fuel tank heating structure comprises a main fuel tank body, wherein the main fuel tank body is arranged on a diesel engine, an oil injection port is formed in the upper end of the main fuel tank body, a heat insulation layer is arranged on the outer side of the main fuel tank body, an S-shaped heating water pipe is arranged in the main fuel tank body, one end of the heating water pipe is connected with a circulating cooling water tank through a water inlet pipe, and the other end of the heating water pipe is connected with the circulating cooling water tank through a water return pipe; a water suction pump is arranged on the water return pipe, and a heating chamber is arranged on the main fuel tank body; an exhaust pipe is arranged on the diesel engine, a tail gas treatment device is arranged on the exhaust pipe, an air inlet pipe is arranged on the exhaust pipe at the rear end of the tail gas treatment device, the air inlet pipe is communicated with one side of the heating chamber, and an air return pipe is arranged on the exhaust pipe at the rear end of the air inlet pipe.

Description

technical field [0001] The invention relates to a diesel engine accessory, in particular to a fuel tank heating structure. Background technique [0002] The application range of diesel engine is very wide. It can be used in automobiles and other fields. Although there are various brands of low-temperature diesel oil suitable for low-temperature use on the market, in normal operation of the vehicle, if the temperature drops sharply in a short period of time, it often causes the It is too late for people to change the oil. At this time, the diesel engine is often due to the inappropriate grade of diesel oil, and the diesel oil precipitates paraffin at low temperature, which leads to the blockage of the oil circuit of the diesel engine and the failure or directly causes the engine to stall. This situation often causes troubles and losses to people in different degrees. , At the same time, the existing diesel engine oil tank often does not get enough insulation measures for the ...

At this time, the diesel engine is often due to the inappropriate grade of diesel oil, and the diesel oil precipitates paraffin at low temperature, which leads to the blockage of the oil circuit of the diesel engine and the failure or directly causes the engine to stall. This situation often causes troubles and losses to people in different degrees. At the same time, the oil pipeline of the existing diesel engine oil tank often does not get enough insulation measures during the use process, and it is easy to cause the service life of the oil pipeline to decrease in the high cold and low temperature area, which increases the probability of maintenance
