Self Study Program 424 – Exhaust Gas Aftertreatment System Selective Catalytic Reduction
Self Study Program 424 – Exhaust Gas Aftertreatment System Selective Catalytic Reduction Design and Function PDF. In this self-study programme, you will obtain information on an exhaust gas aftertreatment system which reduces harmful nitrogen oxides (NOx) in the exhaust gas and is fitted in passenger cars with diesel engines.
In addition to the continuous improvement of internal combustion within the engine, the global tightening of exhaust emissions limits for passenger cars and commercial vehicles with diesel engines also necessitates increasingly higher-performance exhaust gas aftertreatment systems.
With the Selective Catalytic Reduction exhaust gas aftertreatment system, Volkswagen is making a further contribution towards environmental and climate protection.
