摘要:
A binder mixture comprises at least one polymer (A) with saturated main chain that is not a polyester and at least one polyester (B) with a saturated and/or unsaturated main chain, where (i) one of the two components (A) or (B) contains structural units I and/or II, or both components (A) and (B) contain structural units I and/or II, in which the index n is an integer from 1 to 10; and where (ii) at least polyester (B) that contains no structural units I and/or II contains maleic and/or fumaric esters incorporated in its main chain.
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.
