Engine assembly with dual exhaust paths and selective valve
The patent US12071887B2 describes an innovative engine assembly designed for vehicles, featuring an internal combustion engine with a sophisticated exhaust system. This assembly includes a crankcase, crankshaft, and a cylinder block that defines at least one cylinder with an exhaust port. The exhaust system is notable for its dual exhaust paths: a first path leading to a main muffler and a second path directed to a hydrocarbon trap. The hydrocarbon trap is equipped with a material that adsorbs hydrocarbons from the exhaust gas, enhancing emissions control. A pre-muffler is positioned upstream, allowing exhaust gas to flow from the catalytic converter into either the main muffler or the hydrocarbon trap, depending on the position of an exhaust path valve that selectively obstructs one of the paths.
The claims further detail the functionality of the exhaust path valve, which can be controlled by a valve actuator linked to a controller. This controller adjusts the valve's position based on various operational parameters, such as fuel consumption rate, engine temperature, and oxygen levels in the exhaust. Additionally, the assembly includes a purging conduit that allows ambient air to flow into the hydrocarbon trap, facilitating the removal of trapped hydrocarbons back into the engine's air intake system. This dual-path exhaust system not only aims to improve engine efficiency but also addresses environmental concerns by reducing hydrocarbon emissions, showcasing a significant advancement in vehicle engine technology.
