Latest Patents

Among his latest patents is an innovative exhaust gas purification controller for engines. This technology features an NH supply amount controller that reduces and adjusts the supply amount of NH to an SCR catalyst. This adjustment occurs when the exhaust gas flowing into an NO catalyst has a rich air-fuel ratio, allowing for the reduction of NO occluded by the NO catalyst to nitrogen. The controller is designed to set a larger reduction amount of the NH supply when the flow amount of the exhaust gas is detected or estimated to be larger. Additionally, another patent addresses the same exhaust gas purification controller, which adjusts the NH supply amount based on the temperature detected by an NO catalyst temperature detector.
