Added Palm Methyl Ester plus Diesel and Bioethanol Mixtures and Engine Tune-Maintenance of A Research on The Determination of the Effect on Engine Performance

In this study, blends of palm methyl ester (acquired crude palm oil) with Diesel, Bioethanol, Ethanol and Fuel additive mixing certain volumetric ratios and goal of this study is determination engine performance and fuel properties of blends. Experiments performed with 1900 cc 4 cylinders and 4 stroke 105 HP diesel engine and it equipped with common-rail system. Hydraulic engine dynamometer used for performance measurements. Results performed 3 times and average values evaluated. Results are evaluated and statistical analyses are attached. As result, maximum Torque value observed at 2000 rpm as 165,97 Nm with 86 % Diesel (D) + 7% Palm Methyl Ester (PME) + 5% Bioethanol (BE) + 1 % Additive (A) + % 1 Ethanol (E) and max. Power value observed at 3000 rpm as 42.17 kW and min. Specific fuel consumption value observed at 3500 rpm as 157.32 g/kWh with 88 % D + 5 % PME + 5% BE + 1 % A + 1 % E blends.
