How it works in simple Talk


The system usually has 3 different filters, for 3 different reasons.

Exhaust gasses leave the engine and enter the Diesel Oxidation Catalyest (DOC), and with engine heat removes hydrocarbons. It moves down the line into the Diesel Particulate Filter (DPF). The DPF removes soot and ash. At certain intervals, the system will have to regenerate to burn the soot and ash off (Re-Gen Mode). Re-Gen is determent by temperature and soot indicators in the system (sensors). After the exhaust leaves the DPF  it enters into the Selective Catalyst Reduction (SCR). In between the DPF and the SCR there is a Diesel Exhaust Fluid Injector & Urea Filter (DEF). The  DEF in injected into the pipe causing a reaction in the SCR reducing NOX gasses.  Oxide of Nitrogen is a tasteless, odorless gas that destroys the Ozone.  There are controls on the system to monitor how all this works. IF there is visible smoke leaving the engine, this system WILL FAIL IN A HURRY! Any lights on the dash must be taken seriously!   


TRCair def fluid

 TRCair Diesel Exhaust Fluid (DEF) is a composition of urea and water used in transportation applications to reduce the amount of nitrogen oxides (NOx) emitted into the air by diesel engines.DEF is a high purity chemical, comprised of 32.5% urea and 67.5% de-ionized water. This fluid is produced to an international standard (ISO 22241). In order to meet the 2010 EPA Diesel   $11.99 per 2.5 Gal
