The Selective Catalytic Reduction (SCR) system is an advanced exhaust after treatment system to reduce NOx. The engine controls the production of PM by increasing the combustion temperature thus limiting it within the permissible value. NOx increases while doing so, which is then controlled outside using a catalytic reduction process.The SCR system is designed to reduce nitrogen oxide (NOx) in the exhaust gas and purify the exhaust gas by injecting it with AdBlue ®. Be careful not to allow the AdBlue® fluid to run out. If the AdBlue® fluid completely runs out, the SCR system will not operate normally. When the remaining AdBlue ® is low, a message is displayed on the ...The SCR system operates downstream from the engine, removing much of the stress and heat rejection related to EGR-only engines to improve reliability and increase fuel economy.
