Abstract

The invention discloses a quick disassembling method for a particle catcher of a gasoline engine and an auxiliary device thereof. The method comprises the following steps: transforming the particle catcher of the gasoline engine and front and back exhaust air ducts of an original integrated structure; clamping the front and back exhaust air ducts through the auxiliary device and coaxially aligningthe front and back exhaust air ducts to the particle catcher of the gasoline engine in the same direction; putting the particle catcher of the gasoline engine between the front and back exhaust air ducts and placing a sealing gasket; compressing the front and back exhaust air ducts to two ends of the particle catcher of the gasoline engine separately through the auxiliary device; locking a reverse locking mechanism of the auxiliary device; fixedly and hermetically connecting the particle catcher of the gasoline engine to the front and back exhaust air ducts through fastening nuts, separately;and detaching the auxiliary device which is composed of a base, a pipeline clamping mechanism, a pipeline translational transmission mechanism and the reverse locking mechanism. The quick disassembling method simplifies the disassembling process of the particle catcher of the gasoline engine and the disassembling process can be finished by a single person independently, so that the disassemblingefficiency is improved obviously.

Description

technical field [0001] The invention belongs to the technical field of gasoline engine tail gas treatment, and in particular relates to a method for quick disassembly and assembly of a gasoline engine particulate trap and an auxiliary device thereof. Background technique [0002] Gasoline particulate filter (GPF) is a gasoline engine post-treatment device, which can effectively reduce gasoline engine particulate matter emissions by using the interception and regeneration mechanism. [0003] During the development of GPF, it is necessary to repeatedly load and regenerate the GPF for weighing. However, the original GPF and the exhaust pipeline are connected by welding, so they cannot be weighed. The GPF and the exhaust pipeline can only be disassembled and weighed. The disassembly process is cumbersome, inconvenient and time-consuming, resulting in low test efficiency. The workload surged. Contents of the invention [0004] Aiming at the above-mentioned defects in the prio...
