Description

technical field

[0001] The invention relates to a particle filter-regeneration system for diesel vehicles, specifically a spiral diesel vehicle exhaust particle filter-regeneration device with silicon carbide foam ceramics as the carrier of the filter device, which can effectively reduce the particle emissions of diesel vehicles and can be electrified regeneration. Background technique

[0002] Due to the different mixing and combustion methods, the CO and HC in the diesel engine's pollutant emission components are much less than those of gasoline engines, while the particulates are dozens of times or even more than those of gasoline engines. The composition of diesel vehicle particulates is complex, mainly composed of soot, soluble organic matter and some metal oxides. Soot mainly appears in the state of high temperature and oxygen deficiency in the combustion chamber of the diesel engine (such as rapid acceleration of the vehicle or heavy load). Soot (composed of 85% car...
