Title: Innovations of Jean Roy in Exhaust Aftertreatment Systems
Introduction
Jean Roy is a notable inventor based in Middleton, MA (US), recognized for his contributions to the field of exhaust aftertreatment systems. With a total of 8 patents to his name, Roy has made significant advancements in reducing nitrogen oxide emissions in vehicle gasoline engines.
Latest Patents
One of Roy's latest patents focuses on NOx reduction without urea using a dual-stage catalyst system with intercooling in vehicle gasoline engines. This innovative exhaust aftertreatment system includes a first catalytic converter, an oxidation catalyst with a storage catalyst, an air injector, and a cooling unit. The system is designed to operate efficiently by fluidly coupling to the output of a spark-ignited internal combustion engine, which functions in both rich and lean regimes during different driving conditions. The storage catalyst plays a crucial role by storing ammonia produced during rich operation, which then reacts with nitrogen oxide compounds during lean operation.
Another significant patent by Roy is the dual-stage internal combustion engine aftertreatment system using exhaust gas intercooling and a charger-driven air ejector. This system comprises a first stage catalytic converter, a second stage catalytic converter, and a conduit that connects the two stages while passing through an exhaust gas intercooler. The intercooler reduces the exhaust temperature, enhancing the efficiency of the catalytic converters. Additionally, air is ejected into the exhaust conduit to increase oxygen concentration before it reaches the second stage catalytic converter, further improving the system's performance.
