Abstract

The increasing demand for sustainable energy and reduced reliance on fossil fuels has driven the exploration of alternative fuel options. This study aims to evaluate the performance of a motorcycle engine using bioethanol-gasoline blends. Simulations were conducted using AVL Boost software. By applying AVL Boost in innovative ways, the research provides new insights into improving the performance of motorcycle engines powered by bioethanol-gasoline blends, contributing to more eco-friendly transportation. A numerical model of a single-cylinder engine was developed, and various fuel blends were tested to assess performance characteristics at engine speeds ranging from 1000 to 4000 RPM. Single-cylinder spark ignition engines are commonly used in many types of motorcycles. The results showed that the E20 blend achieved a 4% increase in power and improved performance characteristics during tests on engines running on lower ethanol blends.
