Abstract

The utilization of biofuels such as biodiesel in internal combustion engines often results in increased specific fuel consumption and higher emissions of certain pollutants, particularly nitrogen oxides (NOx). This study conducts a systematic and analytical review to explore and organize various engine adjustment strategies aimed at mitigating these drawbacks. The review focuses on recent literature addressing the influence of compression ratio, exhaust gas recirculation (EGR), and injection timing. The analysis reveals that retarding injection timing and implementing EGR are the most effective techniques for reducing NOx emissions, albeit potentially leading to an increase in carbon monoxide (CO) emissions. In contrast, increasing the compression ratio contributes to improved thermal efficiency. The study concludes that combining two or more techniques such as EGR with injection timing adjustments or operating under lean-burn conditions is essential to simultaneously achieve optimal engine performance and effective NOx emission reduction.
