Latest Patents
One of his latest patents is the Adcat exhaust treatment device. This invention relates to a catalytic converter system designed to control exhaust emissions from a combustion engine. The system features three catalyst zones, with the first zone incorporating a light-off catalyst such as palladium. The second zone includes a hydrocarbon adsorber/catalyst, while the third zone is equipped with a catalyst system converter for CO and NO.sub.x. This three-zone system achieves hydrocarbon efficiencies exceeding 98 percent and maintains over 50 percent efficiency in cold performance situations immediately after engine start-up.
Another significant patent by George A. English is the exhaust gas recirculation valve assembly. This assembly is designed to control the recirculation of exhaust gases in an internal combustion engine. It consists of a base with an exhaust gas chamber, a cover, and a valve member that meters exhaust gas passage. An actuator operates the valve, and a heat deflector assembly is included to minimize heat transfer from the exhaust gas chamber to the actuator. This design ensures the durability of the insulative gasket member, enhancing the overall performance of the assembly.
