VALVE ASSEMBLY FOR INTERNAL COMBUSTION ENGINE SYSTEM WITH TURBOMACHINERY

Abstract

An internal combustion engine system includes a turbomachine, an exhaust conduit, a first dosing module, and a valve assembly. The exhaust conduit is coupled to the turbomachine and is configured to receive exhaust from the turbomachine. The exhaust conduit has a conduit internal diameter The first dosing module is positioned along the exhaust conduit and is configured to selectively dose reductant into the exhaust within the exhaust conduit. The valve assembly is selectively actuatable between at least (i) a first position that allows the exhaust to flow at a first flow rate, and (ii) a second position that allows the exhaust to flow at a second flow rate. A first valve assembly distance between the valve assembly and the first dosing module is less than or equal to 3 times the conduit internal diameter.
