Pollutant emissions are a major issue from all existing internal combustion engines, especially from Diesel engines, with nitrogen oxides (NOx) and particulate matter (PM) receiving particular attention. Simultaneous reduction of NOx and PM often presents a challenge to Diesel engine researchers because of the inherent trade-off between them due to their contradictory responses to oxygen content in a fuel. The use of liquid or gaseous biofuels in internal combustion engines, benefits in the reduction of life-cycle CO2 emissions, but suffers from unfavorable NOx/PM emissions trade-off. Hence, it is essential to moderate NOx/PM emissions trade-off in order to effectively use the Rapeseed Methyl Ester (RME) fuel as an alternative to the fossil Diesel fuel in Diesel engines.
