Problems solved by technology

[0005] The purpose of the present invention is to provide a urea tank heating system to solve the problem in the prior art that when the engine coolant is used for heating, the temperature rises slowly, and the crystallized and solidified vehicle urea cannot be melted in time, resulting in excessive emission values.
At the same time, it is also necessary to solve the problem of low heating effect caused by urea tank heating and heater grabbing water

Abstract

The invention discloses a urea tank heating system which comprises an engine, a urea tank, a fuel tank and an SCR tank. The urea tank heating system is characterized by further comprising a solenoid valve, a fuel return opening of the engine is communicated with a fuel inlet of the solenoid valve, a first fuel outlet of the solenoid valve is communicated with a fuel inlet of the urea tank, a second fuel outlet of the solenoid valve is communicated with a fuel return opening of the fuel tank, and a fuel outlet of the urea tank is communicated with the fuel return opening of the fuel tank. According to the urea tank heating system, the urea tank is heated through engine return oil instead of engine cooling fluid, crystallized and solidified automotive urea is molten rapidly, and the discharge value can meet the requirement of the discharge standard rapidly. Meanwhile, as the engine return oil is used for heating, the heating effect of a fan heater can be improved. In addition, the pipeline of the urea tank heating system is redesigned, so that the pipeline structure is simplified, assembly efficiency is improved, and the heating effect of the urea tank is enhanced.

Description

technical field [0001] The invention relates to the technical field of automobile auxiliary parts, in particular to a urea tank heating system. Background technique [0002] The main function of the automobile exhaust system is to discharge the exhaust gas produced by the engine, and at the same time reduce the pollution of the exhaust gas and reduce the noise. With the vigorous development of the automobile industry, the emission standards for automobiles in various countries in the world have been continuously improved, especially the stricter standards for nitrogen oxide pollutants emitted by diesel engines. China has implemented the National IV standard for diesel engine vehicles since July 1, 2013. The most important thing in the standard is to strictly limit the emission value of nitrogen oxide pollutants in the exhaust gas of diesel engines. In order to meet the National IV standard, engine manufacturers The required emission value has begun to use SCR technology (Se...
