Summary

The new 2.0 l 4V TDI engine with Common Rail technology, available in the VW Jetta in the USA from mid 2008, will meet the world's toughest emissions standards as set forth in the BIN5/LEV2 emissions legislation.

In addition to improvements within the engine, further developments to the Common Rail engine already introduced in Europe in the VOLKSWAGEN Tiguan and the AUDI A4 include the implementation of a NOx exhaust after-treatment system.

The engine's technical features include an optimised injector system, a low pressure exhaust gas recirculation system, an innovative cylinder pressure regulation concept as well as a NOx storage catalytic converter. These new engine components require the development of new control algorithms and intensive co-ordination of parameters for the completely new combustion process. The result was the development of a new hardware and software architecture for the engine control unit, which has now been brought into production.
