Volkswagen Group, Ford, Renault-Nissan, BMW, General Motors, Toyota, In 2015, the automotive segment accounted for The chemical reaction is known as "reduction" where the DEF is the reducing agent that reacts with NOx to convert the pollutants into nitrogen, water and tiny amounts of CO2. My presentation was about the Importance of Selective Catalytic Reduction on Diesel Engines. H 2-SCR is selective catalytic reduction of NOx by hydrogen. 110 (2019), Jenoris Muthiya, S., Senthil Kumar, P.: Electrochemical NOx reduction and oxidation of HC and PM emissions from biodiesel fuelled diesel engines using electrochemically activated cell. The method that has been widely adopted is called 'selective catalytic reduction' or SCR. This was possible by applying denitration technology that removes NOx, which is also a PM2.5 causative substance, from exhaust gas. DEF replenishment for heavy-duty vehicles and off-road machines and equipment will vary depending on the operating conditions, hours used, miles traveled, load factors and other considerations. This system has been implemented for a few years and has proven that it's one of the best for nitrogen oxides exhaust emissions treatment. Selective catalytic reduction of NOx using NH3 or hydrocarbons (NH3-SCR or HC-SCR) in oxygen-rich exhaust from diesel engines remains a major challenge in environmental catalysis. Low DEF supply triggers a series of escalating visual and audible indicators to the driver or operator.
