Abstract

Biodiesel is renewable energy that is made from renewable sources such as vegetable oil (palm oil, soybean oil or jathropa oil) through a trans-esterification reaction. Biodiesel can be used as a substitute for diesel fuel or as a mixture with diesel fuel. B-20 and B-30 fuel are a biodiesel mixture with diesel fuel which contains 20% biodiesel and 80% diesel fuel and 30% biodiesel and 70% diesel fuel respectively. The aim of this study is to compare the performance tests of B-20 and B-30 on a diesel engine. Comparison of their performance comprises engine power, engine torque, specific fuel consumption (SFC) in various loads and emissions. Result shows that the B-20 and B-30 performance is affected by the chemical-physical characteristics of fuel, such as kinematic viscosity, cetane number, density and calorific values. Performance test results show that B-30 has 1.69% lower engine power and 0.62% higher SFC than B-20 at a full load condition. In contrast, B-30 has better emissions than B-20 with a 6.71% decrease in smoke opacity.

Abstract

Cold-flow properties merupakan parameter kunci dalam menganalisis ketahanan bahan bakar pada temperatur rendah. Penelitian ini menyajikan analisis cold-flow properties, meliputi titik kabut dan cold filter plugging point (CFPP) dari bahan bakar campuran minyak solar-biodiesel. Analisis varians (ANOVA) dilakukan untuk mendapatkan signifikansi dari pengaruh rasio pencampuran minyak solar-biodiesel terhadap titik kabut dan CFPP bahan bakar. Hasil penelitian menunjukkan rasio pencampuran minyak solar-biodiesel berpengaruh signifikan terhadap titik kabut dan CFPP bahan bakar. Keragaman titik kabut dan CFPP dari basis Minyak Solar 48 dan Minyak Solar 51 dipengaruhi oleh rasio pencampuran biodeisel dengan nilai > 96,7%. Hasil eksperimen menunjukkan cold-flow properties bahan bakar campuran minyak solar-biodiesel dapat diprediksi dengan menghubungkan temperatur awal titik kabut atau CFPP minyak solar murni, dengan rasio pencampuran melalui persamaan model matematika.
