Performance and Emission Characteristics of Thermal Barrier Coating on Diesel Engine Fueled with Cottonseed Biodiesel

Abstract

There is an urgent need to explore the substitute for conventional fossil fuel in light of environmental sustainability. Attempts were made to improve engine efficiency and to reduce greenhouse gasses by certain modification in the use of biofuel. In the present work, experiments have been performed on a single cylinder, four-strokes, direct injection, diesel engine with cottonseed biofuel and its blends. In order to ensure complete combustion of the fuel, cylinder head and piston crown have been coated with yttria partially stabilized zirconia (YPSZ) for a thickness of 0.2 mm. The plasma spray technique has been used for coating engine components. Combustion properties of the cottonseed oil have been improved with the transesterification process. The experimental results showed significant improvement in performance and reduction in emission characteristics of a coated engine. The biodiesel blend B10 and B25 showed good results compared to diesel in an uncoated and coated engine, respectively.
