近年来，轻型柴油车在欧洲的客户接受度和市场渗透率都有了显著提高，这主要是由于发动机设计的重大改进。柴油发动机本质上是一种低排放技术，直到最近，它还不需要催化转化器等二次排放控制技术。然而，在不久的将来，欧共体和美国更加严格的立法对柴油客车提出了一些重大挑战，如果没有二次系统，将很难满足这些挑战。主要的问题是在稀薄燃烧条件下控制NOx，但这必须结合对现代柴油车的其他要求来考虑。有用的精益NOx控制选项必须满足这些其他要求，并表现出精益的NOx性能。如果没有成功的稀有NOx催化剂，柴油车将难以在市场上取得进一步进展。
The light duty diesel vehicle has undergone a dramatic improvement in customer acceptability and market penetration in Europe in recent years, largely because of significant improvements in engine design. The diesel engine is an inherently low emissions technology and until recently, it has not required secondary emission control technology such as catalytic converters. However in the near future more stringent legislation in the EC and USA poses some major challenges for the diesel passenger car which will be difficult to meet without secondary systems. The primary problem is control of NOxunder lean burn conditions but this must be considered in the context of the other requirements imposed on a modern diesel car. Useful lean NOxcontrol options must satisfy these other requirements as well as exhibiting lean NOxperformance. Without successful lean NOxcatalysts the diesel car will struggle to make further advances in the market.
