Abstract
An exhaust gas catalyst system that includes at least one exhaust canister including an inlet separated from an outlet with catalytic components positioned between the inlet and outlet. The at least one exhaust canister receives a flow of exhaust gas. The at least one exhaust canister includes a pair of concentric passages formed therein including a central passage and an outer passage. A split flap valve is positioned in the inlet. An actuator is coupled to the split flap valve. A control unit is operably connected to the actuator and selectively moves the split flap valve closing one of the concentric passages and locally heating a portion of the catalytic components.
