What is DEF?

Diesel Exhaust Fluid  (DEF) is32.5% high purity urea and de-ionized water.

Why DEF?
In order to meet the demands of EPA2010 standards, commercial vehicle manufacturers have evaluated various engine technologies that will provide low emissions and increased performance.  SCR technology or Selective Catalytic Reduction is the option many engine and truck manufacturers have chosen.  In simple terms, a fine mist of emission fluid is dosed into the exhaust that reacts and neutralizes the NOx molecules.  A separate tank is fitted on the SCR truck to house the emission fluid. The rate of consumption for the fluid is 2 to 4% per gallon of diesel fuel. Manufacturers estimate that refueling the emissions tank will occur every other diesel fuel fill up.

The EPA also stated that an infrastructure for the emission fluid must be in place prior to 2010.  Urea producers, equipment manufacturers, truck OEMs, and global distributors are making this happen. The ability to get emission fluid any where in the US and Canada already exists, and later truck dealerships, truck stops and other outlets will have product available.
