KMBROZ DEF is a premium aqueous diesel exhaust fluid which is carefully blended through aqueous urea solution of 32.5% high purity & 67.5% of deionized water. Diesel engines can be run with lean burn air fuel ratio so as to ensure the full combustion of soot & to prevent them from exhausting unburnt fuel. The excess of air leads to generation of Nitrogen Oxides (no,) which are harmful pollutants from the nitrogen in the air. Selective catalytic reduction (SCR) is the leading technology being used to meet the 2010 emission regulation & is used to reduce the amount of NO. released in the atmosphere. KMBROZ DEF is injected in to the exhaust pipeline where the aqueous urea vaporizes & decomposes to form ammonia & carbon dioxide. With the selective catalytic reduction (SCR) catalyst, the No, are reduced by the ammonia & water & Nitrogen which are harmless and these are released through the exhaust. SCR technology as per reports suggest that NO, reduction up yo 90&% can be achieved. The overall reduction of NO, by urea is 2NH2-CO-NH2-4NO+O2 4N2+4H2O+2CO2
