Impact of biodiesel in bioethanol blended diesel on the engine performance and emissions characteristics in compression ignition engine

► Combustion and emission characteristics of bioethanol-diesel fuel were studied. ► Especially, impact of biodiesel fuel was investigated. ► Increasing biodiesel caused the decrease of IMEP and advance of ignition delay. ► Increasing biodiesel induced the significant reduction of HC emission. ► In early injection timings, biodiesel blending caused the decrease of CO and soot.
