Problems solved by technology

[0004] The existing GPF capture and regeneration technology is to filter and capture particulate matter through the filter body. The accumulation of particulate matter to a certain extent leads to a continuous decline in the capture efficiency. The regeneration technology is used to remove the accumulation of particulate matter. The disadvantage is that the capture efficiency and regeneration efficiency are not high enough, resulting in Trapper Damage and Resource Waste

Abstract

The invention provides a GPF oxygen pump auxiliary regeneration device and method coupled with a bipolar charge coagulation system. The device includes a gasoline engine particle filter, a charging device, an electrocoagulation device and an oxygen pump regeneration device, The regeneration device is equipped with an oxygen pump electrolyte sheet and a heating wire; the charging device pre-charges the particulate matter in the exhaust gas of the gasoline engine, and the electrocoagulation device collides and coalesces the particulate matter, and the heating wire heats the particulate matter. The electrolyte sheet is used for oxygen supplementation; the rotation rate of the filter body can also be changed by a stepping motor to achieve the purpose of adjusting the regeneration efficiency. The invention can simultaneously take into account the trapping efficiency and the regeneration efficiency of the particle, does not damage the particle trap, and does not waste resources at the same time.

Description

technical field [0001] The invention belongs to the technical field of tail gas particulate matter regeneration, and in particular relates to a gasoline engine particle trap (GPF) oxygen pump auxiliary regeneration device and method coupled with a bipolar charging and coagulation system. Background technique [0002] As the main influencing factor of air pollution, particulate matter has a huge harm to human health, and environmental protection regulations are increasingly restricting it. China's National VI regulations increase the limit requirements for the amount and number of particulate matter in gasoline vehicles, and the test conditions are also determined by The New European Driving Cycle (NEDC) was changed to the Worldwide Harmonized Light Vehicle Test Cycle (WLTC). Studies have shown that the number of particles in the gasoline engine with direct injection in the cylinder is higher than that in the gasoline engine with port injection, and the amount and number of p...
