SYSTEM OF REDUCING TOXICITY OF EXHAUST Russian patent published in 2010 - IPC F01N3/08 

FIELD: machine building.

SUBSTANCE: system of reducing toxicity of exhaust consists of part of exhaust pipe directing exhaust outside from engine, of catalyst positioned in part of exhaust pipe, and of additive injection valve located in part of exhaust pipe which is positioned in upstream side of the of catalyst flow. The additive injection valve injects additives to catalyst into flow of exhaust in the part of the exhaust pipe. The part of the exhaust pipe has a section for introduction of exhaust which is located in the upstream side of the catalyst flow and includes another part of the exhaust pipe crossing the flow of additives injected with the additive injection valve. Cross section of the channel for the flow of the part of the exhaust pipe has a shape of a fan in essence corresponding to the shape of the downstream side of the injection flow if looked at in a cross direction of the injection flow.

EFFECT: efficient mixing of reducer with exhaust.
