Title: Innovations of Itsuya Kurisaka in Emission Control Systems
Introduction
Itsuya Kurisaka is a notable inventor based in Nisshin, Japan. He has made significant contributions to the field of emission control systems for internal combustion engines. With a total of 5 patents to his name, Kurisaka's work focuses on enhancing the efficiency and effectiveness of emission control technologies.
Latest Patents
Kurisaka's latest patents include an emission control system and method designed to recover a catalyst device from poisoning. This system operates in two control modes. In the first control mode, a temperature-raising operation is performed through post-injection from a fuel injector. In the second control mode, the temperature-raising operation is achieved by adding fuel into exhaust gas from an addition valve. This method ensures that the hydrocarbon concentration in the exhaust gas oscillates within specified ranges. The control system is designed to switch between these modes during regeneration control, optimizing the performance of the internal combustion engine.
Another significant patent involves a control system for internal combustion engines that includes an ECU. This ECU controls the supply of fuel from both an addition valve and an injection valve. It estimates the degree of end-face clogging on the exhaust-gas inflow side of a NOx catalyst. The system adjusts the inlet temperature of the NOx catalyst based on the clogging degree, ensuring efficient operation during regeneration requests for exhaust purification filters and NOx catalysts.
