Diesel Exhaust Fluid

Diesel Exhaust Fluid SERVICE OVERVIEW

Diesel Dogs Fuel Service delivers Blue Sky DEF in Minnesota, Wisconsin and North Dakota.

Diesel Exhaust Fluid (DEF) is a new product required by many heavy-duty trucks, pickups, SUVs and vans delivered after January 2010. DEF fuel is used to destroy harmful emissions in the exhaust and meet the EPA’s latest strict environmental standards.

DEF is non hazardous and consists of 67.5% de-ionized water and 32.5% urea, and is used in combination with Selective Catalytic Reduction (SCR) technology. It is sprayed into the exhaust and combines with a catalyst to break down NOx (a harmful pollutant) into nitrogen and water.

In January 2010 emissions legislation came into force which requires diesel vehicles to significantly reduce harmful emissions of NOx and particulate matter. A good way to meet these standards is to use SCR and DEF. The trucking industry has been split in two by this latest piece of rule making and manufacturers are pursuing two technology pathways. Daimler, PACCAR, Volvo, Mack, Isuzu, Hino, Ford, GM and others are using SCR, while Navistar has decided to go it alone and use an extension of its 2007 MaxxForce EGR technology.
