Summary:

Diesel/Polymethoxy Dimethyl Ether (PODE) blend fuel can significantly reduce emissions from diesel engines. However, emission levels often vary due to high transients during real-world driving conditions. To evaluate the emission and economic performance of diesel/PODE blend fuel, this study analyzed the real-world driving behavior of heavy tractors using different blend ratios (0%, 20%, 30%) across urban, suburban, and expressway road sections, in compliance with the national VI emission standard. Based on Vehicle Specific Power (VSP) bins, the study compared carbon monoxide, carbon dioxide, nitrogen oxide, particulate matter, and fuel consumption rates between pure diesel and blended fuels, providing insights into their performance under varying driving conditions. In addition, specific emissions of pollutants, effective fuel consumption, and effective thermal efficiency for urban, suburban, and expressway sections, as well as for the entire test process, are analyzed to quantify the impact of PODE. The results show that adding PODE reduces CO and PN emissions while increasing NOx emissions, with the most significant reductions in CO and PN occurring under high power output conditions. In actual road driving, CO and PN emissions are highest in urban sections, while NOx specific emissions peak in expressway sections. Adding PODE increases the effective fuel consumption rate. At a 30% blending ratio, the average effective thermal efficiency is approximately 2% higher than that of pure diesel, with varying effects observed at a 20% blending ratio across different sections. These findings provide valuable insights for the further development of diesel/PODE blends and their application in heavy-duty engines by manufacturers
