Latest Patents

Ohkubo's first patent describes a method of manufacturing an exhaust gas purifying catalyst. In this innovative method, a metallic carrier made from heat-resistant alloy steel containing aluminum is prepared. A first alumina slurry is coated onto this carrier, dried, and calcined to form a first alumina layer. Subsequently, a second alumina slurry containing gamma-alumina particles is applied, resulting in a second alumina layer that enhances the catalyst’s effectiveness in purifying exhaust gases.

His second patent is for an exhaust gas cleaning system for vehicles. This system incorporates a particulate filter designed to capture combustible particulates from the exhaust stream of an internal combustion engine. A combustion-promoting material injection device is strategically placed upstream of the particulate filter. It promotes the combustion of particulates effectively, while a bypass exhaust passage and a flow control valve ensure optimal flow regulation, preventing abnormal temperature rises and ensuring uniform coating of the combustible particulates.
