Embodiment Construction

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0047] like Figure 1-4 As shown, the embodiment of the present invention provides a method for packaging the engine catalyst 100. The gasket 200 is sleeved on the outside of the catalyst 100, and the shell 300 is sleeved on the outside of the gasket 200. The packaging method of the engine catalyst 100 includes the following steps:

[0048] S10, obtaining the optimal bulk density range of the liner 200 required for encapsulating the catalyst 100;

Abstract

The invention provides an engine and its catalyst encapsulation method and automobile. The catalyst is sheathed with a liner, and the liner is encased with a casing. The engine catalyst encapsulation treatment method comprises the following steps: obtaining the catalyst required for encapsulation The optimal volume density range of the pad; obtain the current package density of the pad; compare the optimal volume density range with the current package density; determine that the current package density is within the optimal volume density range, and judge the current pad volume density is qualified. The embodiments of the present invention can solve the problem that it is impossible to determine whether the current pad body density is qualified due to tolerance and other reasons.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine, a catalyst encapsulation method thereof and an automobile. Background technique [0002] The catalyst is a key component of the engine aftertreatment system to purify gaseous pollutants, and it is wrapped in the package shell by the gasket. The casing provides enough packaging pressure for the catalyst through the gasket to ensure that the catalyst is fixed and reliable, so that it will not move under the action of the exhaust gas flow. At the same time, the force cannot exceed the maximum packaging pressure that the catalyst can withstand, otherwise the catalyst will rupture. During the mass packaging process of catalysts, the existing packaging methods cannot avoid the phenomenon that the catalyst packaging pressure is too large or too small due to hardware tolerances, which makes some catalyst packaging invalid. Among them, the packaging pressure on the catalyst is...
