Abstract

In road transport, varying fuel flow rates make it hard to maintain a consistent water ratio in non-surfactant emulsion fuels using the Real-Time Non-Surfactant Emulsion Fuel Supply System (RTES). Thus, it becomes more reasonable to establish an appropriate range of water content tailored to a road condition. Therefore, this study aims to evaluate fuel consumption and exhaust emissions of non-surfactant emulsion fuel in light-duty trucks equipped with RTES, focusing specifically on urban conditions. On-road testing and 300-s idling tests were used as the urban conditions to compare diesel with non-surfactant Water-in-Diesel Emulsion (WiDE) fuel with water percentages from low to high concentrations of water, namely WiDE low%, WiDE med%, and WiDE high%. During idling tests, all emulsion variants reduce fuel consumption. WiDE high% exhibits the most substantial NOx reduction of 9.2%. On-road testing reveals comparable WiDE and diesel fuel consumption, despite the RTES increased electrical load. WiDE high% shows an increment for NOx and CO emissions by 11.71% and 202.19%. In conclusion, a 7.4% to 21.1% water content range was suggested for non-surfactant emulsion fuel in urban road conditions.

在城市道路条件下使用轻型卡车的非表面活性剂水包柴油乳化燃料的性能和排放情况

在公路运输中，由于燃料流速不同，使用实时非表面活性剂乳化燃料供应系统（RTES）很难保持非表面活性剂乳化燃料中的水比率一致。因此，更合理的做法是根据路况确定适当的含水量范围。因此，本研究旨在评估配备 RTES 的轻型卡车使用非表面活性剂乳化燃料的油耗和尾气排放情况，尤其侧重于城市路况。以道路测试和 300 秒怠速测试作为城市工况，比较柴油和非表面活性剂柴油包水乳化液（WiDE）燃料，水的百分比从低到高分别为低 WiDE%、中 WiDE% 和高 WiDE%。在空转测试中，所有乳化液变体都能降低油耗。WiDE high% 的氮氧化物降低幅度最大，达到 9.2%。公路测试显示，尽管 RTES 增加了电力负荷，但 WiDE 和柴油的耗油量相当。高 WiDE% 的氮氧化物和一氧化碳排放量分别增加了 11.71% 和 202.19%。总之，在城市道路条件下，非表面活性剂乳化燃料的含水量范围为 7.4% 至 21.1%。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
