TORSI DAN DAYA MESIN DIESEL 2.5L BERBAHAN BAKAR BIODIESEL CAMPURAN MINYAK KELAPA SAWIT

Increasing people's purchasing power for vehicles, especially land transportation, has made energy needs increase. This results in the depletion of fossil fuel reserves that have been used to meet these needs. The lack of reserves makes many researchers look for alternative energy that can improve the combustion process and reduce the use of petroleum fuels. One alternative energy is palm oil biodiesel. Palm oil biodiesel (FAME) is mixed with pure diesel in the levels of 25%, 50% and 75% of palm oil so that it can be used for diesel engine fuel. The study was conducted on a 2477 cc 4-cylinder direct injection diesel engine. The results of the lowest diesel engine torque and power were obtained in a 75% mixture and best obtained in a 25% mixture.Meningkatnya daya beli masyarakat akan kendaraan khususnya transportasi darat membuat kebutuhan energi semakin meningkat. Hal ini mengakibatkan semakin menipisnya cadangan bahan bakar fosil yang selama ini digunakan dalam memenuhi kebutuhan tersebut. Semakin minimnya cadangan ini membuat banyak peneliti mencari energi alternatif yang dapat memperbaiki proses pembakaran serta mengurangi penggunaan bahan bakar minyak bumi. Salah satu energi alternatif adalah biodiesel kelapa sawit. Biodiesel minyak kelapa sawit (FAME) dicampur dengan solar murni dalam kadar 25%, 50% dan 75 % minyak kelapa sawit sehingga dapat digunakan untuk bahan bakar mesin diesel. Penelitian dilakukan terhadap mesin diesel direct injection 4 silinder 2477 cc. Hasil penelitian torsi dan daya mesin diesel terendah diperoleh pada campuran 75% dan paling baik diperoleh pada campuran 25%
