Latest Patents

Murawaki's latest inventions include advanced exhaust gas purification devices. The first device is designed to suppress an increase in pressure loss, incorporating a unique honeycomb substrate and an inflow cell side catalyst layer. This device features a porous partition wall that defines multiple cells, which extend from the inflow side end surface to the outflow side end surface. The inflow cell is created with an open inflow side end and a sealed outflow side end. On the other hand, the outflow cell is structured with a sealed inflow side end and an open outflow side end. The catalyst layer is strategically positioned on the surface in a region extending from the inflow side end. It is noteworthy that the pores of the inflow cell side catalyst layer are filled to a depth of 50% of the partition wall's thickness.

The second patent showcases an exhaust gas purification device that achieves exceptional hydrocarbon (HC) removal performance, particularly under conditions of a rich air-fuel mixture. This device incorporates both a substrate and two catalyst layers. The first catalyst layer is positioned on the surface of the partition wall in an upstream region, while the second layer is integrated within the partition wall in a downstream region. The first catalyst contains a combination of a first metal catalyst and alumina-zirconia composite oxide, while the second layer consists of a different metal catalyst.
