STEP 1: Once poor quality reductant is detected, the engine will have about 25% derate and the warning lamp is illuminated. The engine is allowed to operate for up to 1 hour at this derated level. After the initial hour and poor quality reductant is still detected: STEP 2: A more significant derate of about 40% occurs.The engine load is based on torque; i.e., 100 % engine load implies the maximum torque at a particular engine speed. For instance, if the maximum torque (100 % load) is 300 N·m at an engine speed of 1250 rpm, the 50 % load condition corresponds to a torque of 150 N·m at the same engine speed. In this way, 16 conditions in total were carried out.Selective Catalytic Reduction (SCR) Engines Engine controls the production of particulate matter (PM), thus limiting it within the permissible value, while SCR is an exhaust after treatment device to reduce NOx. SCR spreads aqueous urea solution (AUS 32) into the exhaust stream. Ammonia from AUS32 combines with NOx in presence of catalyst to form harmless by-products like nitrogen and water vapor.
