Effects of cetane number on diesel emissions

In this study, a number of fuels were studied in a single cylinder DI diesel engine to investigate the effects of cetane number on engine emissions. The single cylinder research engine used in this study incorporates the features of contemporary medium-to-heavy duty diesel engines. The engine experiments were run using the AVL 8-mode steady-state simulation of the EPA heavy duty transient test procedure. The experimental fuels using in this study included diesel fuels obtained from different sources with various natural cetane ratings as well as a number of fuels blended by adding two cetane improvers into three base fuels.NRC publication: Ye
