BMW-Sechszylinder-Dieselmotor mit Euro-4-Technik

Wolfgang Mattesist; Karl Mayr; Werner Neuhauser; Fritz Steinparzer

Ab dem 1. Januar 2005 ist fur neue Typprufungen und ab dem 1. Januar 2006 fur die Erstzulassungen in Europa die Abgasgrenzwertstufe Euro 4 fur Pkw zwingend vorgeschrieben. Fur Fahrzeuge mit Dieselmotoren stellt die darin verankerte Halbierung der NOx- und Partikelgrenzwerte eine erhebliche technische Herausforderung dar. BMW hat aktuell damit begonnen, die Volumenmodelle vorzeitig auf die Euro-4-Abgasstufe umzustellen. In diesem Beitrag wird die zur Euro-4-Zielerreichung entwickelte Technik fur die Dieselmotoren der BMW-5er-Reihe, 525d und 530d, beschrieben.

The BMW six-cylinder diesel engine with Euro 4 technology

Wolfgang Mattes; Karl Mayr; Werner Neuhauser; Fritz Steinparzer

The Euro 4 emission standard is becoming mandatory in Europe for passenger cars as of January 1st 2005 (new model homologation) and 1 January 2006 (initial registration). Demanding a reduction of NOx and particle limits by 50 per cent on cars with diesel engines, this new standard represents a significant challenge in technology. BMW has now started converting its volume models ahead of time to the Euro 4 emission standard. This paper describes the technology developed for the diesel engines in the BMW 5-Series — the 525d and 530d — for the purpose of achieving the EU standard.
