What is the difference between the engine exhaust system and the SCR post-processing system?
Automobile exhaust system is an important assembly of emissions and noise reduction, it is mainly by the exhaust pipe, catalytic converter, muffler, tail pipe and other components. And SCR is what we call the selective catalytic reduction technology, the use of urea in the exhaust nitrogen oxides removed to meet the national requirements of the exhaust emission standards, that SCR is part of the car exhaust system.
Mainly used for oil engine exhaust emission standards
Two concepts. Two are father and son system relations. As the emission regulations become increasingly stringent, many modern car exhaust system to increase the post-processing system. To reduce the amount of particulates and nitroxides in the exhaust gas.
