Biodiesel Performance Improvement with the Addition of Al2O3 Nanoparticles on Diesel Engine

Abstract

Biodiesel is used as an alternative fuel that is renewable and environmentally friendly. Biodiesel has several disadvantages compared to diesel: energy with lower heating value, volatility, and viscosity. One of the efforts to reduce the weaknesses of biodiesel is using additives. This study aims to determine the performance of diesel engines from the addition of nanoparticles to biodiesel. This study uses several test samples, including B30, B30+Al2O3 30ppm, B30+Al2O3 50ppm, B30+Al2O3 70ppm, and B30+Al2O3 90ppm. Each sample was tested on a diesel engine. The results showed that the fuel mixture with Al2O3 nanoparticles increased Cylinder Pressure by 13%, Net Heat Release by 41%, and Brake Thermal Efficiency by 76% at a 3kg load. The Smoke Opacity and Specific Fuel Consumption obtained are better than B30.
