The BlueTEC Urea System is designed to drastically control exhaust emissions in light duty vehicles such as SUVs. The BlueTEC engines are currently the cleanest running diesel engines in the world.
BlueTEC is on the cutting edge of having the least automobile gas emissions of it class. Mercedes Benz is releasing these low emission Sport Utility Vehicles right on time for the 2009 season.
This fall is the scheduled release of the ground breaking Blue TEC system for the 2009 auto release season.
The Mercedes Benz Corporation, in the long line of ground breaking achievements, is reaching a new mile stone in America with the BlueTEC system.
The BlueTEC system has been introduced in America at trade shows and in production in other countries since 2006.
How BlueTEC works video
The manufacturer announced the release of the R 320 BlueTEC, ML 320 BlueTEC and GL 320 BlueTEC models on September 13th.
BlueTEC is the branded name for two nitrogen-oxide systems that go beyond the idea of filtering diesel particle soot. The systems are designed to remove NOx from the exhaust.
This system uses Adblue to produce ammonia in the flow of the exhaust system after filtering the diesel particulate out and passing the remaining exhaust through an oxidizing catalytic converter.
Adblue contains a variety of urea solution used in diesel commercial trucking to produce the same affect that the solution is used for in commercial trucking.
In the catalytic converter the catalyst separates the remaining NOx in the exhaust stream into water vapor and nitrogen.
As of 2009, in the United States the emissions limits for the EPAs tier 2 regulations are raised for SUVs, light duty trucks, and cars . Tier 2 brings these vehicles under the same stringent regulations as Tier 1 did for heavy transport vehicles weighing 8,500 lbs. These larger vehicles are still included in the Tier 2 regulation.
There are eight permanent certification levels, with three additional temporary levels. Each vehicle can apply to one of these levels. The temporary levels expire at the end of 2008.
This means that vehicles that were in one of the temporary categories have to find a place in the permanent eight emission certification levels. These levels are called bins.
The Adblue urea system will allow these SUV engines to be pass the Bin 5 emission standards of the Federal Test Procedure.
Trucks and SUVs need to use better emission systems like the urea systems because these larger engines usually put out more pollutants each mile than smaller vehicles. Since the vehicles have to adhere to the same particle emission limit per mile the particle filtering system for SUVs and trucks has to be more thorough.
The BlueTEC Adblue urea solution is the best filtration system that is available to meet the new emission standard for SUVs.
