Latest Patents

Ishihara's latest patents include 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. The controller operates when exhaust gas flowing into an NO catalyst has a rich air-fuel ratio, effectively reducing NO occluded by the NO catalyst to nitrogen. The reduction amount of the NH supply is set larger when the flow amount of the exhaust gas is detected or estimated to be larger. Additionally, the controller adjusts the supply amount of NH to be smaller when the temperature of the NO catalyst is higher, as detected or estimated by an NO catalyst temperature detector.
