Abstract:
1. A selective catalytic reduction system for use with an power system, the selective catalytic reduction system comprising: an exhaust system communicating with a power system and directing exhaust from the power system; a catalyst disposed in the exhaust system for reducing nitrous oxides in the exhaust; an injector communicating with the exhaust system upstream of the catalyst to inject a reductant agent to the exhaust; a coolant system circulating a coolant to the power system and circulating the coolant proximately about the injector to affect a temperature of the injector; a coolant temperature sensor monitoring a coolant temperature of the coolant; and a controller communicating with the coolant temperature sensor and controlling an injection timing of the injector based at least in part on the temperature of the coolant being above a predetermined coolant temperature value.
