Effects of Thermal Barrier Coating Using Various Dosing Levels of Aluminium Oxide Nanoadditive Fuel on Diesel in Compressed Ignition Engine

Abstract

Environmental effects of vehicle exhausts from internal combustions engines which accounts for about 90% of vehicles on the roads is posing a major threat to environmental safety, and it only continues to surge at an alarming rate now than ever. With diesel engines being the most cost-effective prime mover readily available, their contribution to environmental pollution problems is humongous. The harmful contaminants from diesel exhausts are particulate matter (PM) and hydrocarbon and nitrogen oxides (NOx). So, efforts to curb environmental pollution are the need of the hour by making necessary improvements to reduce their local and global environmental impact. In this study, examine the effects of yttria- and alumina-stabilised zirconia coating on the piston head and cylinder lining of a single-cylinder diesel engine, as well as its performance and emissions. Various dosing amounts of nanoparticles of aluminium oxide were utilised as additives to diesel fuel in this study, on both coated and uncoated internal combustion engines. Many coated engine metrics improved significantly as a result of the research. The brake thermal efficiency has increased by 2.1 percent as compared to a conventional uncoated diesel engine, while brake-specific consumption has dropped by 3%, resulting in a reduction in dangerous chemicals.
