Abstract

The invention provides an automobile urea solution heating device and method. The device comprises a stirring tank and a main engine, wherein a coil pipe is arranged on the peripheral wall of the stirring tank; the main engine is communicated with the coil pipe; a pressure relief device is arranged on a pipeline between the main engine and the coil pipe. According to the technical scheme, the coil pipe is arranged on the peripheral wall of the stirring tank, the main engine is communicated with the coil pipe, and the pressure relief device is arranged on the pipeline between the main engine and the coil pipe. Through the adoption of the technical scheme, secondary pollution of an automobile urea solution in the heating process can be avoided, the device is simple in arrangement, and the problems of low heating efficiency of the electrical heating manner and high cost of the engine heating manner can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a vehicle urea solution heating device and a heating method. Background technique [0002] In the prior art, the heating methods of urea solution for vehicles are generally: electric heating and engine heating, but both electric heating and engine heating have their own shortcomings: [0003] (1) The existing electric heating method needs to insert the heating rod into the solution, which will pollute the urea solution for vehicles, and the heating efficiency is low; [0004] (2) Although the function of existing engine heating can be satisfied, the structure is complex and the cost is high. Contents of the invention [0005] The main purpose of the present invention is to provide a vehicle urea solution heating device and a heating method to solve the problems of complex structure and high cost of vehicle urea solution heating in the prior art. [0006] In order ...
