Abstract :In this study, biodiesel was produced from bone marrow by transesterification method. The vast majority of animal bones cannot be collected and recycled. This experimental study was carried out to incorporate unused resources in the economy. In this study, the effects of biodiesel produced from bone marrow on combustion characteristics of diesel engine were investigated. The B20 (mixing 20% of biodiesel and 80% diesel) and diesel (D2) were used as fuel in the tests. The tests were carried out at constant speed (1500 rpm) and different engine loads (20% and 40% of the maximum power output) of a diesel engine with direct injection, four-cylinder, and four-stroke. The combustion characteristics of the engine, such as cylinder gas pressure, heat release rate, cumulative heat release, and mean gas temperature were determined using combustion analysis software (FEBRIS) under 3.6 and 7.2 kW loads. The maximum points of cylinder gas pressures have been very close in both fuels (D2, B20) at the 3.6 kW power output. The peak pressure of the B20 raised with the increase of the engine load. The oxygen in the content and higher cetane number of the biodiesel has raised the peak point of the heat release rate.Keywords : Alternative fuels, Biodiesel from bone marrow, Diesel engine, Combustion characteristics
