Latest Patents

One of his latest patents is an exhaust gas purifying device for diesel engines. This invention efficiently purifies Nitrogen Oxides (NOx) and Particulate Matters (PM) contained in exhaust gases. The device is strategically placed in the exhaust passage of a diesel engine, featuring a catalyst part for reducing NOx and a filter part for removing PM. A diesel fuel injector is mounted at the front of the Nitrogen Oxide reduction catalyst part, enhancing its effectiveness.

Another notable patent is a catalytic filter designed to remove soot particulates from diesel engine exhaust. This filter includes a monolithic oxidation catalyst upstream, which effectively oxidizes gaseous pollutants and volatile organic fractions. Additionally, it features a catalyzed wall-flow filter downstream that facilitates low-temperature combustion of soot particulates collected on the filter. The preparation method of this catalytic filter involves a colloidal mixture solution of platinum group metal salts and other metal salts with a water-soluble polymer and a reducing agent, followed by high-temperature calcining. This invention provides an effective means of abating diesel exhaust pollutant emissions, including PM and gaseous pollutants such as HC, CO, and NOx.
