Detailed study of performance and emission characteristics of diesel engine fuelled with biodiesel and additive

Abstract

The usage of biofuels namely alcohols and biodiesel leads to lower efficiency and higher NO emissions than diesel. The objective of this study is to reduce the emissions and enhance the performance from neat coconut oil biodiesel. To begin, the Diethyl ether, (Oxygenated Additive, OA) is blended to transesterified coconut oil biodiesel (CBD100). OA is varied in CBD at 5 and 10% on a volume basis. Results revealed that the addition of OA to CBD results in no phase separation at all working conditions. Further, adding 10% of OA to CBD lower CO (1.7%), Smoke (2.1%), NO (2.7%) and HC (1.9%) emission than neat CBD. In addition, efficiency increased (1.2%) and fuel consumption lowered (1.3%) by blending OA to CBD at all loads.
