Abstract

Biodiesel is a biodegradable and nontoxic renewable fuel derived from waste, plants oils or animal fats. Biodiesel is considered as a renewable resource and has the potential to reduce the carbon footprint emission.. According to previous literature value, more volume of biodiesel is used to get the same power and torque for the same engine to run. The widely use of fossil fuel nowadays has leads to air pollutants and global warming as the hazardous toxin gases emits from the exhaust. For a solution, biodiesel can be used to reduce the carbon emission from the exhaust. In this project, crude palm oil will be used as the main blending material. The type of biodiesel chosen are B5 (standard diesel), B70, B80 and B90. All these biodiesel is blended and stored at three different storage conditions which are low ( 5  10 C ), ambient ( 25 C ) and high ( 35  40 C ) temperature. Based on the best properties, one type of biodiesel is chosen to be tested in engine dyno to get the performance and emission data. All the data is recorded and evaluated to see the behavior of the engine performance and emission. Results show that performance by using biodiesel is slightly decreasing about 2-8% less of engine horse power and 4-10% less in torque. Biodiesel also produces less exhaust emission about 5-8% of carbon dioxide and hydrocarbons gases. As a conclusion, biodiesel B70 is chosen as the best blend because of its maintained and the lowest value of flash point compared to blending of B80 and B90. Biodiesel B70 can perform satisfactorily during diesel engine operation but it produces less in horse power and torque due to its lower energy compared to standard diesel. it also produces less emission of carbon dioxide and hydrocarbons compared to standard diesel. For future project, use a better gas analyzer to capture all the gases that come out from the exhaust.
