With a total of three patents to his name, Oohira's work focuses on enhancing the efficiency and effectiveness of emissions control systems.
Latest Patents
One of Oohira's latest patents is a selective catalytic reduction (SCR) system. This innovative system prevents the fixation of urea solution within the interior of a dosing valve when the urea solution is not injected. The SCR system is designed to close the dosing valve when the exhaust gas temperature is below the activation temperature of the SCR catalyst. It also features a fixation prevention system that opens the dosing valve and controls a supply module to return the urea solution to the tank, thereby preventing crystallization.
Another significant patent is an exhaust gas purification system that includes a diesel particulate filter (DPF). This system collects particulate matter from exhaust gas and utilizes an exhaust pipe injector for exhaust pipe injection. The DPF regeneration control unit manages the temperature rise of the exhaust gas to regenerate the DPF when the collected particulate matter exceeds a predetermined amount. The regeneration process is carefully controlled to ensure efficiency and effectiveness.
