Fuel tank heating system based on conductive polymer film in diesel engine cold start

Abstract

The invention discloses a fuel tank heating system based on macromolecule conducting film in cold boot of diesel. According to the fuel tank heating system based on the macromolecule conducting film in the cold boot of the diesel, macromolecule conducting film is utilized to be used as heating materials, the macromolecule conducting film is fixed inside a fuel tank, and insulated materials are used for separating the macromolecule materials and diesel oil. The diesel oil is melted through switching on a power before starting. The fuel tank heating system based on the macromolecule conducting film in the cold boot of the diesel is little in heat consumption, simple and convenient in structure, matched with an original fuel tank manufacturing technology, convenient to process, concentrated in heating, and capable of melting paraffin deposited diesel rapidly. The fuel tank heating system based on the macromolecule conducting film in the cold boot of the diesel aims at paraffin precipitation of the diesel at the low temperature, engine oil viscosity becomes larger (when the temperature of engine oil is reduced from 50 DEG C to -20 DEG C, the viscosity is increased by 300 times) under the condition of a low temperature, running resistance is increased at starting, and starting rotary speed is low. The fuel tank heating system based on the macromolecule conducting film in the cold boot of the diesel carries out heating on important parts of an engine starting system, ensures that paraffin-deposited diesel oil is melted in the environment at the temperature of -40 DEG C, and working state at a normal temperature is maintained.

Description

technical field [0001] The invention relates to the field of diesel engine cold start, more specifically, relates to a fuel tank heating system based on a polymer conductive film in the diesel engine cold start, and also relates to a vehicle equipped with the fuel tank heating system. Background technique [0002] With the rapid development of the automobile transportation industry, the use of automobiles is becoming more and more important to people. In a wide range of use environments, whether it is terrain conditions or climatic conditions, there are great differences across the country. For example, in the severe cold environment in the Northeast, the working conditions of diesel engines and other components will change, which will make the starting performance of the car worse and affect people's normal life. [0003] In the cold season, diesel locomotives, ships, drilling rigs, starting equipment, etc. are difficult to start or run normally. It is often seen that dies...

AI Technical Summary

Problems solved by technology

In this way, the fluidity of the diesel oil will be deteriorated, the atomization will be poor, and the ignition lag period will be prolonged.

[0010] Fourth, the output capacity of the battery is reduced

[0016] 5. At present, there are some positive temperature coefficient (PTC) materials and components at home and abroad for patents on low-temperature starting of diesel vehicles and articles on cold starting; but due to the single shape of the heating element (plate or strip), the heating effect , sealing and other problems, so far no commercial application

[0026] In summary, the above-mentioned schemes all have the disadvantages of complex schemes, poor operability, high cost, and inability to meet the requirements.
