In 2008, Audi will be introducing the cleanest diesel technology in the world into series production, together with a new engine and improved catalytic converters. The new TDI engines with their ultra-low emission system combine the spontaneous performance and superior pulling power of today’s TDI power units with outstanding fuel consumption figures and incomparably low emissions.

The new technology will take takes the TDI principle of diesel direct injection with turbocharging that has been proven a million times over and launches it into a whole new dimension. To do this, the diesel-engine development engineers at Audi have incorporated a whole raft of innovative measures into the latest TDI generation: the new piezoelectric common-rail system with an injection pressure of 29,000 psi, the extremely efficient exhaust gas recirculation and optimized turbocharging bring about a dramatic cut in untreated engine emissions. One of the highlights are the combustion chamber sensors that enable even more precise regulation of the combustion processes in the engine – this is the first time that such sensors have been fitted on any engine in the world, marking yet another Audi innovation.

Clean-running and high-tech diesel is what the new engine is all about and aiming to reduce nitrogen oxide emissions by up to 90 percent. The ultra-low emission system runs on a biodegradable additive in the form of a solution called AdBlue. Tiny doses of this solution are injected upstream from the DeNOx catalytic converter. The ultra-low emission system as a whole comprises the catalytic converter, the metering module, the AdBlue tank and heated lines, as well as an extensive system of sensors. The comprehensive emission control system is rounded off by the separate two-way catalytic converter and the highly efficient, electronically controlled diesel particulate filter.
