Chemistry. Diesel exhaust fluid (DEF) from a separate tank is injected into the exhaust pipeline, where the aqueous urea vaporizes and decomposes to form ammonia and carbon dioxide. Within the SCR catalyst, the NO x are catalytically reduced by the ammonia ( NH 3) into water ( H2O) and nitrogen ( N 2 ), which are both harmless;
The Consumable Fluid. Diesel exhaust fluid is a mixture of synthetic, high-purity, automotive-grade urea and deionized water. This liquid is clear, nontoxic, nonflammable, non-explosive, and generally nonhazardous. Additionally, DEF is classified as a minimum risk for transportation.

Diesel Exhaust Fluid is formulated with 32.5 percent urea and 67.5 percent deionized water. In storage or when the engine is not in use, DEF will freeze at 12°F (-11°C). At this concentration level, the urea and the water freeze and thaw at the same rate – ensuring that you always have the correct amount of each.

Most of these systems use diesel exhaust fluid (a mixture of urea and deionized water) sprayed into the exhaust stream to break down the generated NOx into harmless nitrogen and water.
DEF, also known as AdBlue®, AUS 32 and ARLA 32, is a non-toxic, colourless, odourless and non-flammable fluid. Stored in a dedicated tank in your car, DEF is injected into the exhaust system to clean exhaust gases. It breaks down nitrogen oxide (NOx) emissions into harmless water vapour and nitrogen gas.
