Abstract:
An exhaust aftertreatment system for treating exhaust flow from an internal combustion engine, and associated method, allows for independent control of exhaust flow through plural exhaust legs of the exhaust aftertreatment system. The independent control of exhaust flow is carried out by adjusting a valve positioned in each the exhaust legs based on a value of a signal generated by a flow measurement device positioned along at least one of the exhaust legs. The valves can be adjusted to force a target flow in a exhaust leg, relative flow among exhaust legs, exhaust temperature in an exhaust leg, exhaust backpressure and/or imbalance within the exhaust legs.

Claim (Index 14):
A method of exhaust aftertreatment for a multi-leg exhaust aftertreatment system, the multi-leg exhaust aftertreatment system including plural parallel exhaust legs adapted to receive exhaust from an internal combustion engine, each of the plural parallel exhaust legs including a diesel oxidation catalyst, a diesel particulate filter, and an independently controllable exhaust valve, the method comprising:\n flowing exhaust gas through the plural parallel exhaust legs; detecting an exhaust mass flow or exhaust volume flow characteristic in at least one of the plural parallel exhaust legs; determining amounts of exhaust mass flow or exhaust volume flow in the plural parallel exhaust legs based on the detected exhaust mass flow or exhaust volume flow characteristic; and individually adjusting the exhaust valves in each of the plural parallel exhaust legs based on the determined amounts of the exhaust mass flow or exhaust volume flow.
