Abstrakt: Crude palm oil (CPO) is one of the vegetable oil that has potential for use as a fuel in diesel engine. Despite years of improvement attempts, the high viscosity and the major chemically bound oxygen component in the biodiesel fuel play as a key element during combustion process. Purpose of this study is to explore how significant the effect of preheated biodiesel blends on the engine performance and emission. The blending of biodiesel was varied from 5vol%(B5)~ 45vol%(B45) and preheated fuel temperature from 40oC~60oC. The engine speed was varied from 1500 rpm~3000 rpm and the load test conditions of 100% are considered. The performances parameter study of diesel engine in brake power, torque and flywheel torque are described together with the emissions parameter such as opacity, hydrocarbon (HC), nitrogen oxide (NOx), carbon oxide (CO), carbon dioxide (CO2) and oxygen (O2). Under high load condition, preheated biodiesel blends were found enhancing the combustion process, resulting in better performances. Increased preheated fuel temperature, higher in torque value and brake power increases significantly as the engine speed increases.
