摘要: A reductant mixing system having injector and mixing plate positioned within mixing canister is disclosed. Injector discharges reductant directly into vehicle exhaust gases. Mixing plate effects turbulence to mix gases for NO reduction. Mixing plate includes plurality of arms each having surface area and extending from center of plate, barrier region defined by collective surface areas of arms and substantially centered for diverting fluid flow outward, and first and second cut-outs, which allow the gases diverted by barrier region to pass mixing plate into adjacent canister of exhaust treatment system. Each of the first cutouts is defined by outer edge between adjacent arms, and second tier of cut-outs defined by inner edge proximate end of each arm.

摘要: 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.

摘要: A method is provided for estimating the NOx content of exhaust gas produced by an internal combustion engine. The method includes determining a first NOx estimate corresponding to the NOx level output by the engine during a first engine operating condition. The method further includes determining a second NOx estimate corresponding to the NOx level output by the engine during a second engine operating condition. The method further includes determining a compensation factor based on intake manifold pressure and applying the compensation factor to the first and second NOx estimates to arrive at a final NOx estimate.

摘要: An ammonia (reductant) injector for delivering a ammonia into an engine exhaust stream is disclosed. Generally speaking, the injector has a body with an inlet fluidly coupled to a plurality of channels within the body, a plurality of discharge ports, each port being fluidly coupled to at least one channel, and an ammonia feed line connected to the inlet of the body. The plurality of discharge ports are preferably spaced one from another such as to optimize the dispersion of ammonia from the ports throughout a cross-sectional portion of an engine exhaust stream.
