摘要： An exhaust emission control filter is provided that can reduce the pressure loss and has a high exhaust conversion performance and particulate matter capturing performance. An exhaust emission control filter includes: a filter base material having a wall flow structure; and an exhaust conversion catalyst carried on partitions of the filter base material. The median gas pore diameter (D50) of the filter base material after the exhaust conversion catalyst is carried on the filter base material is 17 μm or more. The half width of the gas pore distribution of the filter base material ranges from 7 to 15 μm. The exhaust conversion catalyst is ununiformly carried in a high-density layer having a relatively high density of the exhaust conversion catalyst and a low-density layer having a relatively low density of the exhaust conversion catalyst. The maximum gas pore diameter of the high-density layer is 11.7 μm or less.

摘要： An internal combustion engine exhaust system supporting structure includes a body fastening portion, an exhaust fastening portion, a bracket, and a stay. The body fastening portion is provided on a power plant or a vehicle body located on a side of an exhaust passage extending from an internal combustion engine to a rear of a vehicle so that exhaust emissions flow from the internal combustion engine to the rear of the vehicle. The bracket is fastened to the body fastening portion. The stay is fastened to the exhaust fastening portion and has lower stiffness than the bracket. The bracket and the stay are fastened to each other at a connecting portion so that a vertical distance between the exhaust fastening portion and the connecting portion in a vertical direction is greater than a vertical distance between the body fastening portion and the connecting portion in the vertical direction.
