He has made significant contributions to the field of automotive emissions control, particularly in the development of innovative NOx treatment systems. With a total of 5 patents to his name, Satoh's work has been instrumental in advancing cleaner technologies for vehicles.
Latest Patents
One of Satoh's latest patents involves a NO reduction system that comprises a NO treatment catalyst and an air-fuel ratio control switch. This system is designed to change the air-fuel ratio of exhaust gas to either a lean or rich state. The NO treatment catalyst consists of a first catalyst layer containing a solid acid catalyst capable of adsorbing ammonia, and a second catalyst layer that includes a noble metal and a cerium oxide material. The configuration of these layers allows for efficient conversion of NO to nitrogen, significantly reducing harmful emissions.
Another notable patent is an NOx purifying catalyst that operates effectively even under low-temperature conditions, such as those found in diesel engine automobiles. This catalyst processes NOx in exhaust gas through rich/lean control of the air-fuel ratio. It features a first catalytic layer containing β-zeolite with iron and/or cerium elements, and a second catalytic layer made of noble metal and cerium oxide-based material. This innovative design enhances the purification of NOx, contributing to cleaner air.
