DEF Information

DEF, or Diesel Exhaust Fluid, is a NOx reduction agent comprised of 32.5% urea and 67.5% purified water. When used in diesel engines with Selective Catalytic Reduction (SCR) technology, DEF helps convert NOx into harmless nitrogen and oxygen. Without DEF, NOx works to form smog, acid rain and nitric acid in the air, all of which are bad for health and the environment.

SCR & the DEF Process

SCR is the leading technology in NOx reduction for diesel engines. NOx reduction is necessary because NOx can contribute to acid rain and smog, making it harmful to our health and environment.

In order to reduce NOx emissions, SCR requires a catalytic converter and a reducing agent known as Diesel Exhaust Fluid (DEF). DEF is injected directly into the exhaust upstream of a catalyst, where DEF vaporizes and decomposes to form ammonia. The ammonia then works in conjunction with the SCR catalyst to break down NOx into harmless nitrogen and water vapor. The diagram on the right illustrates the Diesel Exhaust Fluid process.

Quality Standard

DEF should be certified by the American Petroleum Institute (API). The International Organization for Standardization (ISO) has set quality requirements (22241) for diesel engines. The API Certification program ensures that Diesel Exhaust Fluid meets the specifications of ISO. Ports Petroleum sells DEF from manufacturers who have been certified by the American Petroleum Institute to meet the standards of ISO 22241.
