AI Technical Summary

⚠Technical Problem

Existing particulate filter regeneration devices have complex structures and poor regeneration effects, making it difficult to effectively improve the filtration capacity of particulate filters.

⚗Method used

An exhaust treatment system was designed, including an oil-gas mixing section, an air circuit assembly, a liquid circuit assembly, and a fluid driving section. The fluid driving section generates negative pressure in the oil-gas mixing section, causing exhaust gas and fuel to mix and form an oil-gas mixture. Through the coordinated design of the intake cone, the fluid mixing section, and the fluid treatment section, the particulate filter can be regenerated efficiently.

🎯Benefits of technology

It improves the regeneration effect of the particulate filter, reduces pollutant emissions, enhances the efficiency of exhaust gas treatment, and simplifies the structure of the exhaust treatment system.

Abstract

The application relates to the technical field of vehicle exhaust treatment, and provides an exhaust treatment system and a vehicle. The exhaust treatment system comprises a particle trap and a regeneration device, the regeneration device comprises an oil-gas mixing part, a gas path assembly and an oil path assembly, and a fluid driving part connected between the oil-gas mixing part and the particle trap, and the fluid driving part can drive an oil-gas mixture in the oil-gas mixing part to flow into the particle trap. The exhaust treatment system provided by the application sets one fluid driving part, which can facilitate the smooth flow of exhaust gas and fuel into the oil-gas mixing part, the exhaust treatment system has a simple structure, and the oil-gas mixture can smoothly flow to the downstream, which is helpful for the combustion regeneration of the particle trap, has a good exhaust treatment effect, and can reduce the emission of pollutants.
