Audi Clean Diesel TDI has been available world wide for some time and will be making its debuet in North America in April 2009. Knowing Audi has had huge success with Diesel and even applied it to there race program and are now on the 2nd generation race car development, I think we will be seeing alot more diesel.
Below is a digram of seven Truths About Audi Q7 clean Diesel.
1. If 33 percent of all vehicles driven were Audi Q7 TDIs, it would save approximately 350,000 Barrels of oil a day.
2. The Audi Q7 3.0-Litre TDI engine produces 137 foot pounds of torque per liter of displacement-far more then a comparable gasoline engine.
3.The Audi Q7 TDI engines common-rail injection system can inject precise amounts of fuel into each chamber up to five times per combustion cycle, which is the main reason traditional diesel clatter has been silenced for good.
4. The Q7 TDI with its 26-gallon fuel tank can drive more then 600 miles with out a fill up or a distance from Washington D.C. to Savannah Georgia.
5. In Actual real world driving, the Audi Q7 TDI will use up to 40 percent less fuel then comparable gasoline engines.
6. The Fuel to air ratio in Audis Q7 3.0 Liter TDI engine can exceed 140:1 in no load or idle conditions, which is one reason why TDI technology saves fuel
7. Each Fuel injector in the Audi Q7 3.0 liter TDI engine will open and close approximately 1 billion times over its service life.
I would like to mention the AdBlue that Audi will be using, if you open the fuel door of your Audi Q7 TDI you will see two portals; one is for clean diesel and the other for the AdBlue. AdBlue is a chemical solution that is introduced downstream in the exhaust system, the purpose: “To separate the remaining microscopic compounds of Nitrogen Oxide (NOx) and form the non toxic molecules of Nitrogen and Oxygen – both of witch are abundant in the atmosphere.
The AdBlue tank is separate from the Clean Diesel fuel tank and only needs to be filled and serviced every 15,000 miles. Knowing that Audi recommended service intervals are every 10,000 miles this coincides with regular service, so you should never have to worry about the AdBlue if you are going to your authorized Audi Service Department.
