Self Study Program 420 – Audi 2.0L TDI Engine with Common Rail Injection System

VAG SSP 420. The 105 kW (143 hp) 2.0-litre TDI engine featuring common rail (CR) injection technology marks the birth of a new generation of dynamic and efficient diesel engines. It reinterprets the qualities of the TDI concept while addressing the future challenges facing  environmental protection in particular.

The 2.0-litre TDI CR engine is based on the successful 2.0-litre pump injector TDI engine, whereby the combination of the 2.0-litre TDI unit with common rail technology sets new standards. The new 2.0-litre TDI CR engine built at Audi Hungaria Motor in Györ already meets the high standards of the Euro 5 exhaust emission standard due to come into effect in 2010.

Thanks to the use of common rail technology, the 2.0-litre TDI CR engine has major advantages with regard to exhaust emissions, acoustics, weight and overall build height. The TDI engines deliver high torque at low revs. The goal for the development of the 2.0-litre TDI CR engine was to enhance this character.
