Abstract: With the increasingly severe energy crisis and environmental pollution, biodiesel has attracted widespread attention as a renewable and clean alternative fuel. This paper investigates the effects of B40 biodiesel on diesel engine performance and emissions. By analyzing the physicochemical properties of biodiesel, referencing existing research data and literature, and combining these with experimental results, the study details the impact of biodiesel on engine power output, fuel economy, combustion characteristics, and pollutant emissions. The results show that biodiesel affects engine power and fuel economy to some extent, increases nitrogen oxide (NOx) emissions from the engine, and changes the proportion of NO2 in combustion products, resulting in a slight increase in NOx levels in SCR-treated exhaust.
