Investigation of in-cylinder gas stratification of diesel engine during intake and compression stroke

Shen, Zhaojie; Liu, Zhongchang; Tian, Jing; Liu, Jiangwei - In: Energy 72 (2014) C, pp. 671-679

To control diesel emissions of NOx and PM (particular matter), there has been increasing interest in EGR (exhaust gas recirculation) stratification in recent years. However, only a few works have discussed in-cylinder distribution using two-dimensional EGR concentration contour. For a better...

Diesel engine development in view of reduced emission standards

Knecht, Walter - In: Energy 33 (2008) 2, pp. 264-271

Diesel engine development for use in light-, medium- and heavy-duty road vehicles is mainly driven by more and more stringent emission standards. Apart from air quality related emissions such as nitrogen oxides and particulates, also greenhouse gas (GHG) emissions are likely to become of more...
