The Effect Characteristics Cetane Number of Commercial High-Speed Diesel Fuel-Biodiesel Palm Oil-Based Blends on CFR engine

Abstract

Abstract Renewable energy is an important issue for substituting fossil fuels in the world. Biofuel is one of the most used fuels for transportation, mining, and the industrial sector. The government of Indonesia’s policy has mandatorily used biofuel for the blend to fossil fuel. Biodiesel production from palm oil base has good characteristics for substitute/blend to high-speed diesel (HSD) in the market. The objective of this study was to investigate the effects of cetane number value of variant HSD-biodiesel blend and the methodology with blending two types HSD and biodiesel (0%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 50%, 60%, 70%, 80%, 90%, 100%). The measurement of cetane number used a CFR engine in accordance with ASTM D 613. The result of this study was that the increasing percentage of biodiesel blend influenced the increasing value of cetane number, but the increasing value of cetane number was not linear. Therefore, biodiesel can be used as a cetane booster for HSD.
