概要

Application of biodiesel fuel (BDF) to diesel engine is very effective to reduce CO_2 emission, because BDF is carbon neutral in principle. However, it is possible that the exhaust emission characteristics of diesel engine fuelled with biodiesel is not good. In fact, it has been frequently reported that biodiesels yield an increase in NO_x emission in many diesel engines. Therefore, some aftertreatment systems are needed for meeting the future emission regulations using biodiesel. In this study, rapeseed methyl ester (RME) was applied to diesel engine equipped with NO_x storage reduction catalyst (NSR) and diesel particulate filter (DPF). The NO_x reduction rate of NSR was drastically decreased by using RME, even if injection quantity of RME for rich spike was enhanced. This rich spike injection using RME also caused an increase in PM emission.
