Comparison Performance CI Engine of Using High-Speed Diesel Fuel-Biodiesel Blend (B30) and (B40) on Diesel Engine Dyno Test

Abstract

Biodiesel is one of the renewable energy resources to produce from palm oil. Now, the Indonesian government has established a mandatory for biofuel use, especially biodiesel blend with high-speed diesel (B30). The future will increase the percentage of blended biodiesel up to 30%. This study aimed to compare performance of diesel engines used B30 and B40. The methodology started from blending fuel high-speed diesel CN 48 with two biodiesel samples of B30 and B40, and performed density test, distillation test, viscosity test, and test performance using diesel engine 2400CC on the dyno test bench. The result of this study showed that the power engine decreased by about 1% and torque decreased by about 1.4%, and emission opacity decreased 3.2%.
