Operating a 2010 Diesel Model or Later?

Then you need to know about SCR and DIESEL EXHAUST FLUID (DEF).

Alexis Oil offers Blue Sky Diesel Exhaust Fluid which is available for purchase in Totes, Drums, Cases. We also offer Diesel Exhaust Fluid Tote Kits as well as dispensing equipment such as air pumps, level pumps, and rotary pumps.

What is SCR (Selective Catalytic Reduction)?
SCR is a post-combustion emission reduction technology and a key element of the SCR process in the Diesel Exhaust Fluid (DEF).

It is stored on the vehicle in a tank adjacent to the diesel fuel tank and injected into the exhaust system in front of the Selective catalytic Converter.

DEF is used in Selective Catalytic Reduction (SCR) systems to change the Oxides of Nitrogen (NOx) emissions in diesel exhaust to Nitrogen and water. Nitrogen makes up about 78% of the air we breathe every day.

DEF is a non-toxic solution based on a mixture of 32.5% urea and 67.5% purified water.

When DEF is injected into the exhaust, it hydrolyses to ammonia which in turn triggers the chemical reaction that is the Selective Catalytic Reduction process and converts the NOx in the exhaust into harmless nitrogen and water.

Increase Fuel Economy
It’s the LAW! For diesel engines produced after January 1, 2010, DEF is REQUIRED for emissions after-treatment.

Bottom Line:
Why do we need to control emissions and what role do you have to play?
Large portions of the U.S. do not meet the national ambient air quality standards.
Diesel exhaust has been implicated in an increased risk of lung cancer and respiratory disease AND diesel trucks and buses comprise 28% of the Nitrogen Oxides (NOx) and 20% of the Particulate Matter (PM) from U.S. mobile source emissions.
PM and NOx from diesel contribute to asthma and other serious respiratory health problems.What has the EPA done about it?
Why do we need to control emissions and what role do you have to play?
Tightened the emissions standard. Starting back in 1999, with a phased-in approach over eleven years to 2010, the EPA has taken us to where we are now. EPA launched the National Clean Diesel Campaign (NCDC) The NCDC has two parts: Regulations & Voluntary program
What do the regulations cover?
These regulations cover new engines and mandates for low sulfur diesel fuel. They also cover Light-duty Tier 2 passenger vehicles (like a pick-up with an engine greater than three-liters), Heavy-duty Diesel highway vehicles, Non-road Diesel Engines, Locomotive and Marine transportation. Upcoming standards for Ocean Going Vessels will be fully phased in by 2016.How is this being phased in?
Light-duty Tier 2: fully phased in 2009. That means that the Silverados, the F-250s and the Ram pickups will have the SCR technology and will require DEF.
Heavy-duty Diesel highway vehicle phased in January 1, 2010. From the over-the-road 18-wheeler to the local public utility service truck – if it’s made after January 1, 2010 it will have to meet the standards.
Non-road Diesel Engines (e.g., the farm tractors and combines that help feed the world): fully phased in by 2014.
Locomotive and Marine: fully phased in by 2017
Ocean Going Vessels: fully phased in by 2016 for vessels with SCR technology.
