Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Bluetec shopping experience:

1. Compare - without doubt the biggest advantage that the Bluetec offers shoppers today is the ability to compare thousands of Bluetec at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.

2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about

3. Testimonials - don't know anybody that has bought a Bluetec? Wrong! If the Bluetec is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.

4. Questions - Got a question about Bluetec then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....

5. Reputation - Never heard of the company selling Bluetec? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Bluetec and build up a picture of their reputation for sales, returns, customer service, delivery etc.

6. Returns - still worried that even after all of the above your Bluetec wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.

7. Feedback - happy with your Bluetec then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.

8. Security - check for the yellow padlock on the Bluetec site before you buy, and the s after http:/ /i.e. https:// = a secure site

9. Contact - got a question about Bluetec, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.

10. Payment - ready to pay for your Bluetec, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.

BlueTec is Daimler AG's name for its two nitrogen oxide (NOx) reducing systems, for use in their Diesel automobile engines. One is a urea-based reductant called AdBlue, the other is called NOx_Adsorbers and uses an oxidizing catalytic converter and particulate filter combined with other NOx reducing systems. Both systems are designed to reduce pollutant emissions.

The BlueTec was on the Ward's 10 Best Engines list for 2007.

Uses Mercedes-Benz introduced the systems in the Mercedes-Benz E-Class (using the 'DeNOx' system) and Mercedes-Benz GL-Class (using 'AdBlue') at the 2006 North American International Auto Show as the E320 and GL320 Bluetec vehicles. This system makes these vehicles 45-state and 50-state legal, respectively in the United States, and is expected to meet all emissions regulations through 2009.

A Jeep Grand Cherokee with the same BlueTec engine is also expected, and Mercedes announced tentative plans for a BLUETEC/electric hybrid Mercedes-Benz S-Class.

Volkswagen has introduced the VW_Jetta Clean TDI, the VW_Tiguan concept and the VW Touareg BlueTDI as part of the BlueTec program. All are expected to be introduced in the American market in 2008. The Jetta and the Tiguan use NOx Adsorbers, while the Volkswagen Touareg uses a Selective Catalytic Reduction catalytic converter.

Daimler has entered an into agreement with Volkswagen and Audi to share BlueTec technology with them in order to increase the Diesel passenger-vehicle market in the US.

In August 2007 VW Group announced that cooperation on BlueTec with Daimler AG would end. Reasoning for this change is due to the recognition of the VW TDI branding. VW did not want to use a competitors branding for a product they would introduce into the market. http://money.cnn.com/news/newsfeeds/articles/newstex/AFX-0013-18676102.htm

Rationale The BlueTec system was created because the processes that give diesel engines efficient fuel economy also creates extra emissions of certain pollutants. High compression ratios and lean air-fuel mixtures make high combustion temperatures, which results in more nitrogen oxides and Diesel Particulate Matter (also known as smoke) being released into the Earth's atmosphere. While the particulate matter can be controlled with higher injection pressures and particulate filters, the big challenge is limiting NOx (Tier 2 regulations in the US are 0.05 gram per mile of NOx, which is ⅛ of the 0.40 limit in the European Union).

Process The Bluetec system will use two catalytic converters specifically targeting NOx. The first converter traps the NOx, and later releases it to the second converter which then converts it to nitrogen (N2) and Water (molecule) (H2O). This will make a diesel car legal in 45 states. But to make it pass the more stringent regulations of California, Maine, Massachusetts, New York and Vermont, AdBlue (NH4) will have to be introduced into the system, making the conversion more complete.

NH_3 + NO_x \rightarrow \; N_2 + H_2O

The whole exhaust system would work like so:
  • A Diesel oxidation Catalytic converter reduces the amounts of carbon monoxide (CO) and hydrocarbons (HC) released from the exhaust.
  • A NOx_Adsorbers catalytic converter begins a preliminary removal of oxides of nitrogen.
  • A Diesel_particulate_filter traps and stores soot particles, burning them off when the filter gets full.
  • If the above are not sufficient to meet the exhaust specifications, a Selective Catalytic Reduction (SCR) catalytic converter will take the remaining nitrogen oxides and convert them to nitrogen and water. AdBlue will be injected into the exhaust gas stream to enable the conversion.
