Diesel Exhaust Fluid

TATA Autocomp Diesel Exhaust Fluid

D.E.F is essential for the correct operation of an advanced pollution control technology installed in the exhaust system called Selective Catalytic Reduction(SCR). When injected into hot exhaust as a fine mist and passed over a catalyst, DEF helps convert NOx (nitrogen oxide) into nitrogen gas and water vapour-- two clean and harmless components of the air we breathe. DEF is stable, colourless and odourless. When Use in BS-IV engines it increase the diesel average by 3-4%. DEF consumption is approximately 2-3% of fuel use but varies with duty cycle, operation, geography and other factors.
