Abstract
A system for mixing ammonia (reductant) with engine exhaust includes an exhaust flow created by a vehicle engine, an ammonia feed line passing into the exhaust flow, an injector connected to the feed line and positioned within the exhaust flow, the injector having at least one port for discharging ammonia into the exhaust flow, and a mixing plate positioned within the exhaust flow downstream of the ammonia injector and stabilizing at least one of either the feed line and the injector. An aspect of the invention is to stabilize the injector by attaching the mixing plate to the feed line to provide such stability. Alternatively or additionally, the mixing plate is attached to the injector to stabilize. The feed line may even pass through the mixing plate.
