Advanced combustion engines for low emissions and high efficiency

01 Oct 2008

Air pollutant emissions from motor vehicles have fallen dramatically over the past two decades as a result of continuing improvements in engine and aftertreatment technologies to meet lower regulated emissions limits, and in the quality of fuel used to power these vehicles. As a result, attention is increasingly focused on vehicle efficiency and fuel consumption in order to address concerns over future energy supplies and greenhouse gas emissions while maintaining, and further reducing, exhaust emissions performance. Lightduty vehicle technology is evolving rapidly to respond to these new challenges.
