摘要: A system and method controls injection of a reductant agent in a selective catalytic reduction system. The system and method include an injector injecting the reductant agent to an exhaust system directing exhaust from a power system. A coolant system circulates coolant proximate to the injector. A coolant temperature sensor monitors a coolant temperature of the coolant. A controller adjusts the injection timing of the injector based at least in part on the coolant temperature.
