Audi: economical and clean in the future

Ingolstadt / nurnberg, 25. July 2007 – audi wants to go to the future with clean and economical engines. At a press conference of the bavarian auto climate initiative, which in addition to audi is also BMW, the association of the automotive industry (VDA), the ADAC and the bavarian state government, the manufacturer presented a series of innovative technologies. They should worries for more efficiency and less CO2 out.

Economical E-modell in the volume series

The ingolstadter focus mainly on the diesel: audi launches its TDI strategy in 2008 with a modified three-liter V6 in the ranks A4 and Q7. The basis is the already offered TDI engine from the A5 with 240 hp and 500 newton meters of torque. By 2010, audi wants to offer the new technology in many vehicle and performance classes. The TDI principle of diesel direct injection with turbocharger is optimized for this: a new piezo-common rail system with 2000 bar injection prere, highly efficient emission prere and optimized charging should bring significantly lower engine raw emissions. A highlight are the combustion chamber sensors used worldwide for the first time. You should make a pracere scheme of incoming incidence.

Ultra-low-emission system with additional variable

The clean high-tech diesel is the new TDI generation through the downstream ultra-low-emission system. It should reduce nitrogen oxide emissions by up to 90 percent. To operate the system, adblue is used, a biodegradable additional solution. It is injected in a minimum dosage in front of the denox catalyst. The complete ultra-low-emission system consists of catalyst, dosing module, adblue tank, heated lines and a comprehensive sensor. The additional oxidation catalyst and a regulated diesel particulate filter complete the exhaust gas purification system.
