Abstract: Disclosed is a particulate collecting filter structure for a diesel engine. The filter structure includes a plurality of through cells axially and regularly arranged therein. The through cells are partitioned by thin cell walls. Half of the through cells are sealed by a sealant at outflow ends thereof, and the remaining half of the through cells are opened at outflow ends thereof. The filter structure is provided in the diesel engine to solve conventional problems caused by pressure loss. It is possible to avoid the problems in which operating conditions and fuel consumption efficiency are worsened, convenience of operation is reduced, and, at worst, operation of the engine is stopped, because overstrain is applied to the mechanically controlled diesel engine.

Abstract: The present invention provides a method of regenerating a catalyst using the oxidizability of NO 2 , a method of regenerating a catalyst, including the step of injecting NO or air into an oxidation catalyst to generate NO 2 , and a method of regenerating a catalyst, including the step of directly injecting NO or air into a regeneration catalyst, rather than an oxidation catalyst. Further, the present invention provides a useful method of regenerating a catalyst, in which the sintering of the catalyst can be prevented because the regeneration temperature is decreased, in which coke is burned, thus increasing the regeneration efficiency of the catalyst, thereby maintaining the activity of the catalyst, and in which the cost of maintaining the catalyst is low.
