Assessment of E10 Fuel Compatibility with Modern Gasoline Engines: Analysis of Fuel Consumption, Emissions, and Material Impact

Abstract

This paper investigates and evaluates the compatibility of E10 biofuel (10% ethanol and 90% gasoline) with modern gasoline engines using the Diesel-RK simulation software. Two representative models, Honda Vision and Toyota Vios, were selected for analysis. The study focuses on fuel consumption, emission indices (CO, CO₂, NOx, HC), and the impact on fuel system materials, comparing E10 with traditional gasoline. Results indicate that E10 reduces CO and CO₂emissions by 5-8% and 4-7%, respectively, but increases fuel consumption by approximately 3-4% due to its lower energy density. Additionally, E10 requires material compatibility assessments, particularly for gaskets and fuel pumps, due to ethanol’s hygroscopic and corrosive properties.
