Abstract:

The present invention is an exhaust gas recirculation (EGR) valve for an engine having an exhaust gas recirculation cooler operable for receiving exhaust gas from an exhaust, and delivering the exhaust gas to an intake. The present invention also includes an exhaust gas recirculation bypass passage operable for receiving exhaust gas from an exhaust, bypassing the exhaust gas recirculation cooler, and delivering the exhaust gas to an intake, as well as a single valve operably associated with the exhaust gas recirculation cooler and the exhaust gas recirculation bypass passage. The single valve is selectively operable for opening or closing flow from the exhaust to the exhaust gas recirculation cooler, the exhaust gas recirculation bypass passage, or both, the single valve also operable for metering flow therebetween.

International Classification:

F02B 47/08

US Classification:

12356812, 12356819

Abstract:

An engine assembly () comprising an engine, a plurality of coolers, a plurality of bypasses, and at least one actuator (). The engine has an exhaust manifold and an intake manifold. The gaseous fluid exiting the exhaust manifold is recirculated to the intake manifold. The exhaust gas passes through either an air cooler or a bypass. At least one actuator is operably connected to the plurality of bypasses. The bypasses have a valve () which is actuated to control the flow of the gaseous fluid through the bypass as both the bypass and the cooler. Therefore, when a single actuator is used to control the valves in both bypasses, the valves in the bypasses have the same relationship with the inlets so that a single actuator movement will control both valves in the same manner.
