With a total of two patents to his name, his innovations address the pressing need for reducing harmful emissions from vehicles, thus enhancing environmental protection.

Latest Patents

Kazuto Maehara's latest patents focus on sophisticated exhaust gas purification devices designed for internal combustion engines. The first patent describes an exhaust gas purification device consisting of an exhaust passage that includes a catalyst. The design incorporates a bend created by bending a portion of the exhaust passage directly upstream of the catalyst. This bend facilitates a collision of the exhaust gas against a corner portion between the catalyst's inlet end and the wall of the exhaust passage, increasing pressure at that corner compared to other areas. An additive injection valve is fitted outside the bend, strategically injecting additives that fall onto the catalytic converter's inlet end face.

The second patent outlines an improved exhaust gas purification device featuring a more integrated design. It consists of an exhaust passage for guiding exhaust gas from the engine to the outside and includes a catalyst within the passage. Additional components include an injection path on the upstream side of the catalyst, equipped with an additive injection valve for supplying additives directly to the catalyst through this path. An inflow portion is also integrated where the exhaust passage and the injection path merge, enabling a portion of the exhaust gas to flow into the injection path, thus enhancing the effectiveness of the purification process.
