Scania DI16 SCR User Manual SCR (Selective Catalytic Reduction) is a system in which reductant is added to the exhaust gases in order to reduce the nitrogen oxide (NOx) content. This document describes SCR system components and how they should be connected. Reductant is a solution consisting of urea and water, and is usually called AdBlue®, DEF, ARLA 32 eller AUS 32, depending on the market. If the engine is equipped with an SCR system, the reductant is added to the exhaust gases upstream of the catalytic converter. This reduces nitrogen oxide emissions.
Scania DI16 SCR Owners Manual Reductant in accordance with ISO 2241 contains 32.5% by weight of urea and freezes at approximately -11°C (12°F). When the solution freezes, ice and urea always maintain the same concentration. Always store reductant at a temperature between 11°C and 30°C (12-86°F), scania trucks,trucks scania,scania trucking,scania cars,scania car,scania truck usa.
Scania DI16 SCR Reductant is highly corrosive. For this reason, only pipes and couplings resistant to urea may be used in the SCR system. Always rinse away reductant spillage on connections and other parts with lukewarm water to prevent corrosion. If reductant seeps into electrical connections or electrical cables, these must be renewed.
