Abstract

The current investigation examined how the combined use of Modified Operating Parameter (MOP) and Thermal Barrier Coating (TBC) enhanced the performance, combustion, and emission characteristics of a diesel engine running on Punnai oil fuel. In this study, it was found that the Punnai oil blended with diesel could effectively increase engine efficiency and decrease emissions under MOP and TBC. Based on the results of the testing, the 60 P (where P denotes the blend percentage of Punnai oil in Diesel) fuel blend proved to be the most efficient fuel blend for the engine in terms of Cylinder Pressure, Heat Release Rate (HRR), and Brake Thermal Efficiency (BTE) in comparison with the 70 P and 80 P fuel blends. Furthermore, the 60 P blend demonstrated lower emissions of Carbon Dioxide (CO₂) and Hydrocarbons (HC) than the other blends, although it produced higher levels of Nitrous Oxide (NOx) and Smoke Opacity. The study indicates that utilizing a 60 P Punnai oil fuel could result in improved engine performance and reduced emissions.

改进工况参数和热障涂层对punnai混合油柴油机性能的影响

目前的研究考察了修改操作参数（MOP）和热障涂层（TBC）的结合使用如何提高使用Punnai油燃料的柴油发动机的性能、燃烧和排放特性。本研究发现，在MOP和TBC条件下，Punnai油与柴油混合可以有效地提高发动机效率，降低排放。根据测试结果，与70p和80p混合燃料相比，60p（其中P表示Punnai油在柴油中的混合百分比）混合燃料被证明是发动机在气缸压力，热量释放率（HRR）和制动热效率（BTE）方面最有效的混合燃料。此外，60p混合物的二氧化碳（CO2）和碳氢化合物（HC）排放量低于其他混合物，尽管它产生了更高水平的一氧化二氮（NOx）和烟雾不透明度。研究表明，使用60 P的Punnai油燃料可以提高发动机性能并减少排放。

期刊介绍： Journal of Engineering Research (JER) is a international, peer reviewed journal which publishes full length original research papers, reviews, case studies related to all areas of Engineering such as: Civil, Mechanical, Industrial, Electrical, Computer, Chemical, Petroleum, Aerospace, Architectural, Biomedical, Coastal, Environmental, Marine & Ocean, Metallurgical & Materials, software, Surveying, Systems and Manufacturing Engineering. In particular, JER focuses on innovative approaches and methods that contribute to solving the environmental and manufacturing problems, which exist primarily in the Arabian Gulf region and the Middle East countries. Kuwait University used to publish the Journal "Kuwait Journal of Science and Engineering" (ISSN: 1024-8684), which included Science and Engineering articles since 1974. In 2011 the decision was taken to split KJSE into two independent Journals - "Journal of Engineering Research "(JER) and "Kuwait Journal of Science" (KJS).
