Embodiment Construction

[0038] The following detailed description is merely exemplary in nature and is not intended to limit the disclosure, application, or uses. Reference has been made in detail to the various forms of the present disclosure, examples of which are shown and described by way of illustration only. As those skilled in the art would realize, the various forms described may be modified in various different ways, all without departing from the spirit or scope of the present invention.

[0039] The catalytic particulate filter according to an aspect of the present disclosure may be applicable to various devices and vehicles that obtain energy by burning fossil fuels and discharge gas generated during the combustion into the atmosphere. Although this specification shows one example of a catalyst particulate filter suitable for a vehicle, the disclosure should not be construed as being limited to this specific example.

[0040]The vehicle is equipped with an engine for generating power. E...

Abstract

A catalyzed particulate filter comprising: at least one inlet channel extending in a longitudinal direction with one end allowing fluid inflow and the other end being blocked; at least one outlet channel extending in a longitudinal direction with one end being blocked and The other end thereof allows fluid outflow; at least one porous wall defining a boundary between adjacent inlet and outlet channels and extending in a longitudinal direction; and a support coated with a catalyst.

Description

[0001] Cross-references to related applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2015-0172450 filed on December 4, 2015, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to a catalyzed particulate filter, and more particularly, to a catalyzed particulate filter that minimizes the increase in back pressure and provides a longer contact time between the catalyst and the fluid ( larger contact area). Background technique [0004] Exhaust gas from an internal combustion engine (for example, a diesel engine or various combustion equipment) contains particulate matter (PM). When discharged into the atmosphere, such PM can cause environmental pollution. To this end, the exhaust system is fitted with a particulate filter that traps PM. [0005] According to the flow rate of the fluid, the particulate filter can be classified into a flow-through part...
