Title: The Innovations of Takashi Takakura
Introduction
Takashi Takakura is a notable inventor based in Hino, Japan. He has made significant contributions to the field of exhaust purification systems, holding a total of 3 patents. His work focuses on improving environmental standards through innovative technologies.
Latest Patents
One of Takakura's latest patents is an exhaust purification system. This system includes an exhaust passage where exhaust gas flows. A burner is arranged within the exhaust passage, creating a combustion space for fuel. A NOx adsorbent is strategically located downstream of the combustion space to absorb nitrogen oxide from the exhaust gas. Additionally, a selective reduction catalyst is positioned downstream of the NOx adsorbent. An adding valve is placed between the selective reduction catalyst and the combustion space, allowing urea water to flow through a connection passage toward the adding valve. Notably, part of this connection passage runs through the combustion space.
Another significant patent is a ceramic honeycomb filter and exhaust gas-cleaning method. This filter comprises a ceramic honeycomb structure with porous partition walls that define multiple flow paths. Plugs are disposed inside these flow paths, allowing exhaust gas to pass through the pores of the partition walls, effectively removing particulates. A catalyst is carried on the partition walls and/or the plugs, enhancing the filtration process. The design ensures that particulates are removed by injecting unburned fuel and/or hydrocarbon upstream of the inlet-side plugs, maintaining optimal temperatures for catalyst activation.
