STUDI EKSPERIMENTAL PEMBAKARAN BAHAN BAKAR PERTALITE DENGAN CAMPURAN BIOETHANOL DARI LIMBAH BREM TERHADAP KINERJA MESIN SEPEDA MOTOR HONDA PCX 160CC

Reserves of fossil energy (fuel oil) are decreasing day by day, while the need continues to increase. The need for fuel can be reduced by making savings and looking for alternative energy sources. One of the renewable and environmentally friendly alternative energy sources to replace fuel is bioethanol. Motor vehicles are expected to always be in high performance. Engine performance may decrease due to use of inappropriate fuel. The purpose of this study was to analyze how much influence pertalite fuel with a mixture of biethanol from brem waste (E0, E10, E20, E30, E40, and E50) had on the performance of the Honda PCX 160cc motorcycle engine (torque, effective power, fuel consumption, and mean effective pressure). Pertalite (E0) and biopertalite (E10, E20, E30, E40, and E50) fuels will be tested to determine the value of torque, power, and fuel consumption at ambient temperature between 15-35ºC, Air humidity between 30%-70% RH and variations in engine speed are 2000 rpm to 9000 rpm with a range of         1000 rpm. Then calculated the value of the average effective pressure. Engine performance testing using the Full Open Throttel Valve method based on SAE J1349 (Engine Power Test Code-Spark Ignition and Compression Ignition-Net Power Rating). The results of this study indicate that the largest torque value using E50 fuel is 1.41 kgf.m at 6000 rpm engine speed. The highest effective power value uses E50 fuel of 12.2 HP at 7000 rpm engine speed. The lowest fuel consumption uses E50 fuel of 0.08 liters/hour at 3000 rpm engine speed. The largest average effective pressure using E50 fuel is 12.21 kg/cm2 at 2000 rpm engine speed.  Keywords: pertalite, bioethanol, biopertalite, engine performance.    &nbsp
