Abstract

The invention discloses a rapid carbon accumulating device of a particulate filter. The rapid carbon accumulating device comprises an engine, and further comprises the particulate filter, a water-cooling EGR system and an inlet air filter which are mounted behind an engine exhaust pipe and can be rapidly disassembled. The engine, the particulate filter, the water-cooling EGR system and the inlet air filter are sequentially connected, an EGR control valve is arranged between the water-cooling EGR system and the inlet air filter, and the EGR control valve is connected with a control module. Therapid carbon accumulating device can rapidly accumulate carbon black with enough mass.

Description

technical field [0001] The invention belongs to the technical field of engine exhaust systems, and in particular relates to a fast carbon accumulation device for a particle trap. Background technique [0002] In addition to stricter quality requirements for PM particles, the existing emission regulations also increase the number requirements for PN particles, and particle filters will be widely used in light-duty passenger vehicles. Automobile particulate filter is an important part of the car, the main function is to collect the soot produced by the incomplete combustion of the engine, through the CO 2 and O 2 A secondary chemical reaction occurs to reduce particle emissions to meet emission regulations. [0003] Due to the changeable boundary environment of vehicle operation, a complete set of development, calibration and verification process is required for particle traps. Among them, the establishment of the carbon accumulation and consumption model of the particle fi...
