Diesel Exhaust Fluid (DEF)

About DEF

Diesel exhaust fluid is one of the key elements of the Selective Catalytic Reduction (SCR) process used by most medium and heavy-duty engine builders to meet EPA 2010 regulations. BlueDEF™ is a nontoxic solution of 67.5% purified water and 32.5% ultra pure automotive grade urea. BlueDEF™ is not a fuel or fuel additive. Instead, when injected into the exhaust stream and passed over a catalyst, BlueDEF helps convert NOx into nitrogen gas and water vapor – two harmless and natural components of the air we breathe. BlueDEF™ is stable, colorless and odorless, and meets ISO Standards 22241 for purity and composition and is an American Petroleum Institute (API) certified diesel exhaust fluid. These are the highest quality and safety standards in place to ensure optimum SCR performance.

Making sure you do not run out of BlueDEF™ in a SCR equipped truck is simple – watch the Diesel Exhaust Fluid (DEF) gauge, which is part of the diesel fuel gauge, for when it is time to refill. DEF is stored in a dedicated tank next to the fuel tank on the driver's side. The tanks range in size from 6 to 23 gallons depending on the truck's application. The DEF tank fill opening is designed to accommodate a DEF fill nozzle to ensure only DEF is put into the tank. A diesel fuel nozzle will not fit into the DEF tank opening.

Diesel Emissions Reduction Requirements

EPA 2010 is the final phase of the Environmental Protection Agency's (EPA) plan to assure that medium-duty and heavy-duty trucks run cleaner by the year 2010. In fact, EPA 2010 standards require that NOx levels from new trucks be reduced to almost zero. Faced with strict and well defined engine emission regulations, the trucking industry has worked hard to meet these important environmental regulations, while ensuring that maximum fuel efficiency and engine performance was not sacrificed.

In order to meet the new EPA 2010 requirements, most diesel engine manufacturers are using Selective Catalytic Reduction (SCR) technology. The SCR system uses diesel exhaust fluid to convert NOx emissions into nitrogen and water vapor – two harmless and natural components of the air we breathe. SCR technology, and the integral role diesel exhaust fluid plays, has been successfully used in Europe for years and has proven to provide near-zero NOx emission levels while delivering improved fuel economy and engine reliability.
