The new 2.0 TDI e Concept is able to show the effectiveness of Audi’s new Modular Efficiency program. The said vehicle has the capacity to undercut the consumption limit of five liters per 100 km by using just 4.9 liters for 100 km on the EU cycle. With the A4, Audi is able to bring forward its whole package of innovative engineering solutions. As for the start/stop system or the energy recuperation system that is still being developed, Audi enthusiasts can expect future Audi vehicles to exhibit it.

The people behind Audi’s diesel engine development combined a whole package of innovate measures to come up with the latest developments in TDI generation. The new piezo common rail system with an injection pressure of 2,000 bar, highly efficient exhaust gas recirculation and the optimized turbocharger produce greatly reduced raw emissions. The presence of combustion chamber sensors, the first of its kind, serves as one of the highlights. These sensors allow the combustion processes inside the engine to be regulated even more precisely.

When combined with the ultra low emission system, the latest TDI engine in the end becomes the clean high-tech diesel. This combination is able to reduce nitric oxides by up to 90 percent. It uses the additive AdBlue, which is a biologically degradable water-based solution. A minute dose is injected into the system upstream of the DeNOx converter.

The A4’s ultra low emission system comprises the catalytic converter and a metering module, the AdBlue tank and heated lines, and an extensive system of sensors. The additional oxidation catalytic converter and the highly efficient regulated diesel particulate filter complete the comprehensive exhaust emissions control system.
