Scr Exhaust System

Oxides of nitrogen carbon monoxide hazardous air pollutants volatile organic compounds.

Scr exhaust system.

An scr selective catalytic reduction system is a system installed on diesel vehicles to reduce harmful nitrous oxide nox emissions. Shop the best 2017 yamaha scr950 exhaust for your motorcycle at j p cycles. The exhaust aftertreatment devices that are applied to vehicles are diesel oxidation catalysts doc diesel particulate filters dpf and selective catalytic reduction scr catalysts. 3 1 4 3 catalytic reduction systems selective catalytic reduction scr systems selectively reduce no x emissions by injecting ammonium nh 3 into the exhaust gas stream upstream of a catalyst.

Selective catalytic reduction scr is a means of converting nitrogen oxides also referred to as no x with the aid of a catalyst into diatomic nitrogen n 2 and water h 2 o a reductant typically anhydrous ammonia aqueous ammonia or urea solution is added to a stream of flue or exhaust gas and is adsorbed citation needed onto a catalyst as the reaction drives toward completion carbon. The pollutants that are reduced include. Manufacturing quality reproduction parts for classic cars for over 30 years. Gas lines brake lines transmission oil cooler lines vacuum lines and exhaust systems are manufactured to oem specifications using cnc equipment.

Miratech s selective catalyst reduction system scr reduces regulated exhaust pollutants for stationary reciprocating diesel dual fuel and lean burn natural gas engines. Using a combination of physical mechanisms and chemical reactions these systems can under the right conditions achieve near complete removal of particulates. Ipu s scr system alone can achieve a 99 8 reduction of nox emissions. Selective catalytic reduction for gensets will reduce nox emissions by combining exhaust gases with the reductant adblue a type of urea and passing it over a catalyst.

It works by injecting an automotive grade urea or diesel exhaust fluid def through a specially designed catalyst into the exhaust stream of a diesel engine. In this video i explain how the adblue system works.
