Abstract

The present invention relates to the technical field of urea box heating for vehicles and discloses a urea box heating system and method for a full vehicle. The urea box heating system and method for the full vehicle comprises a urea box. A urea solution is contained in the urea box. An air inlet of the urea box communicates with an air outlet of a turbocharger through a first heating pipeline. An air outlet of the urea box communicates with an air inlet of the turbocharger through a second heating pipeline. The urea box heating system and method for the full vehicle further comprises a power pump which is arranged on the first heating pipeline and can supply circulating power to hot air flowing out of the air outlet of the turbocharger. The heating system has the advantages of high heating efficiency, energy saving and environmental protection and complete oxidation and reduction.

Description

technical field [0001] The invention relates to the technical field of vehicle urea tank heating, in particular to a vehicle urea tank heating system and a heating method thereof. Background technique [0002] At present, for vehicles treated with SCR (Selective Catalytic Reduction Technology) technology, it is necessary to spray urea solution into the exhaust gas emitted by the engine, so that the urea solution can undergo a redox reaction with the nitrogen oxides in the exhaust gas, thereby generating pollution-free Nitrogen and water vapor are vented to the atmosphere. The urea solution is usually located in the urea tank. If the vehicle is running in a low environment, the urea solution in the urea tank is prone to freezing, which will block the urea pump, urea nozzle and urea solution delivery pipeline, resulting in urea The supply system is not working properly. [0003] Based on the above analysis, it is necessary to design a urea tank heating system for the whole v...
