Embodiment Construction

[0014] Such as Figures 1 to 3 As shown, the present invention provides a light passenger car SCR heating and cooling pipe structure, which includes a heating and cooling pipe 1, and the heating and cooling pipe 1 connects the engine 6 with the urea tank 7 and the urea injection unit 8 to pass through the engine. 6. The urea tank 7 is heated, and the urea injection unit 8 is cooled.

[0015] The invention uses the engine as the power and energy end, connects it with the urea tank and the urea injection unit, provides heating and cooling through the engine, and maintains a normal working state.

[0016] As an improvement of the present invention, it also has a urea tank 7 , and the heating and cooling pipe 1 is also connected to the water inlet pipe 4 of the urea tank 7 .

[0017] As a preferred embodiment of the present invention, there is a water cutoff solenoid valve 3 between the heating and cooling pipe 1 and the water inlet pipe 4 of the urea tank 7 . As a preferred imp...

Abstract

An SCR (selective catalytic reduction) heating and cooling tube structure of a light coach comprises a heating tube and a cooling tube. The heating tube and the cooling tube connect a motor with a urea tank and a urea spraying unit, so that urea in the urea tank can be heated by the motor, the urea spraying unit can be cooled by the motor, and a normal working state is maintained.

Description

technical field [0001] The invention relates to an automobile component, in particular to an SCR heating and cooling pipe structure for a light passenger car. Background technique [0002] The automotive sector is a complex industry that includes the combination of many materials and components. Among them, the normal work of related pipe fittings and pipelines is an important part of the development of modern technology in the automotive industry. [0003] In the field of light bus chassis technology and exhaust system, the structure of SCR heating and cooling pipes for the Euro V emission stage is an important technical issue in this field. [0004] For example, in the domestic bus market, Cummins uses in-cylinder combustion optimization and selective catalytic reduction (SCR) technology to meet Euro V emission standards. Euro V emission standards require nitrogen oxides (NOx) and particulate matter (PM) emissions to be reduced to 2 grams per kilowatt-hour and 0.02 grams...
