Abstract

Reducing carbon emissions is a global priority, and methanol-gasoline blended fuels are gaining attention as a promising alternative for cleaner combustion. This study aims to investigate the effects of methanol fraction (0–100%) and injection timing on combustion efficiency, ignition delay, and emissions using a single-cylinder engine under high and low load conditions. Under high load conditions, low methanol fractions caused knocking, limiting spark timing advancement and reducing efficiency. As methanol fractions increased, combustion efficiency improved, and NOx emissions significantly decreased, especially above 50%, due to methanol’s high latent heat of vaporization. In low-load conditions, methanol enhanced combustion efficiency by shortening combustion duration, attributed to rapid flame propagation and its oxygen content. THC and CO emissions decreased, while CO2 slightly increased due to complete oxidation. The findings demonstrate methanol’s potential for achieving high-efficiency, low-emission combustion and offers experimental data for optimizing engine operation and blending strategies for future application..
