With a total of 3 patents to his name, his work has been instrumental in improving environmental standards in automotive engineering.
Latest Patents
One of Hideo Kaiho's latest patents focuses on an exhaust gas purifying system for internal combustion engines. The invention aims to enhance the purification of hydrocarbons (HC) at the start of the engine by adequately retarding the rise of the temperature of an HC adsorbent. The system includes a three-way catalyst positioned downstream of the exhaust manifold, an adsorbent-catalyst containing zeolite, and an additional catalyst downstream of the adsorbent-catalyst. Notably, the heat capacity of the exhaust gas passage connecting the three-way catalyst and the adsorbent-catalyst is designed to be greater than that of the exhaust manifold. This innovative design includes features such as a substrate, partition, or muffler across the exhaust gas passage, with the exhaust tube shaped in a convex and concave configuration.
Another patent by Kaiho describes an exhaust system that incorporates a three-way catalyst, an adsorbent-catalyst capable of absorbing hydrocarbons, and an electrically heated catalyst. This system effectively purifies low boiling-point hydrocarbons within approximately 20 seconds from engine start and high boiling-point hydrocarbons within about 80 seconds. The design minimizes electric power supply by energizing the electrically heated catalyst after the other catalyst has completed its function.
