Audi puts the world’s cleanest diesel technology into series production.

Audi has now taken the TDI’s evolution to the next level by developing the world’s cleanest diesel engine.

To achieve this, the TDI combustion process was systematically improved. The injection system, rated for injection pressures of up to 2000 bar, a radically enhanced exhaust gas recirculation system and an optimised turbocharging system are at the heart of this evolution. A new feature is the integrated cylinder pressure control system. This package of modifications marks the first step towards bringing about a further, marked reduction in untreated engine emissions. The second step will be to reduce the nitrous oxide emissions to a minimum through the use of an active exhaust gas aftertreatment system.

The ultra low emission system allows emissions to be minimised, while enhancing fuel economy by combining intra-engine modifications with an innovative exhaust gas aftertreatment system. The objective was the systematic improvement of the TDI
technology to meet future EU6 limits, as well as LEV II/BIN5, the most stringent limits in force today, so the system is suitable for roll-out, both in Europe and world-wide.

The aims of this Self-Study Programme

This Self-Study Programme describes the design and function of the exhaust gas aftertreatment system using AdBlue reduction agent. By working through this Self-Study Programme, you will be able to answer the following questions:

– What are the exhaust emission limits for petrol and diesel engines according to the applicable emission standards?
– Which process(es) does the combustion chamber pressure sender control?
– Which system components are integrated in the exhaust gas aftertreatment system?
– Why do the elements in the reduction agent tank have to be heated in cold conditions?
