Linking biofuel chemistry to engine performance: A study from Vietnam

The chemical composition of biofuels, determined by their biological origin, directly influences their combustion characteristics and, consequently, engine performance. This study focuses on developing a testing system to quantify the relationship between the biochemical properties of biofuels and the operational capacity of internal combustion engines. The platform enables precise measurement of how variations in fuel composition—affected by feedstock type and production process— impact engine parameters. Validated on a Mitsubishi 4G54 engine with over 90% accuracy, the system provides a critical tool for biochemists and bioengineers. It facilitates the screening and optimization of biofuels by linking their molecular-level properties to macroscopic engine behavior, thereby accelerating the development of efficient and environmentally sound biofuels tailored to the Vietnamese context.
