Latest Patents

Among his latest innovations, Saito has developed methods for exhaust gas purification that involve a sophisticated catalyst system. One notable patent describes a process where an exhaust gas purification catalyst is integrated into an exhaust system of an internal combustion engine. This catalyst is composed of an upper layer that contains first carrier particles—comprising inorganic oxide and rhodium—and a lower layer made up of second carrier particles.

In this method, the upper layer is designed to feature a rhodium-rich portion located near its surface, strategically positioned on the upstream side of exhaust gas flow. The rhodium-rich area spans from greater than 50% to 80% of the upper layer's length, with limited depth from the outermost upper surface.

Another important patent outlines an exhaust gas purification catalyst device that encapsulates similar principles. This device incorporates an upper layer with the first carrier particles and rhodium, as well as a second lower layer with additional carrier particles. The upper layer is characterized by a rhodium-enriched area that extends from the upstream end to 50% of the upper layer's length and reaches a depth of 18 micrometers.
