Indian Oil Clearblue: For BS6 engines with SCR

Indian Oil has signed an agreement with Cummins Technologies for bulk dispensing of the oil marketing company's Diesel Exhaust Fluid (DEF).

Branded as IOC ClearBlue, it will be used in Cummins' engines with SCR (Selective Catalytic Reduction) systems as well as engines using the Cummins SCR systems. Bulk dispensing is claimed to reduce price of the product compared to pre-packed ones. ClearBlue will be available at select Indian Oil fuel pumps across India.

India will move to BS6 emission norms from April 1, 2020. Automobile companies are using technologies like diesel particulate filter, selective catalytic reduction (SCR) and exhaust gas recirculation (EGR). Among these, SCR systems require DEF, an aqueous urea solution, for effective reduction in Nitrogen oxide emissions.
