With an impressive portfolio showcasing 16 patents, he has consistently demonstrated his commitment to innovation and performance enhancement in internal combustion engines.
Latest Patents
Among his latest inventive achievements is the development of an exhaust purification system designed for internal combustion engines. This system employs a wall flow type particulate filter positioned within the exhaust passage of the engine, where combustion occurs in an excess oxygen environment. The innovative feature of this particulate filter is its incorporation of a solid acid, which possesses an acid strength that is higher than sulfurous acid but lower than sulfuric acid. To maintain the efficacy of the particulate filter, Oshikawa introduced a process called ash atomization. This process temporarily alters the state of the particulate filter by lowering the oxygen concentration in the incoming exhaust gas while increasing the filter's temperature to facilitate efficient ash removal.
