Abstract

Abstract: In recent times, enormous efforts are being made by researchers for the enhancement of the overall efficiency of internal combustion engines. In this paper, an attempt has been made to evaluate the fluctuations in performance and emission aspects of High Velocity Oxy Fuel (HVOF) thermal spray coated internal combustion engine. The internal headlining of the piston was coated with Zirconium Dioxide and Aluminium Oxide. Engine performance was evaluated at four different injection timing retardations such as 22°CA, 20°CA, 18°CA and 16°CA and compared with baseline 23°CA injection timing. Using diesel, the coated internal combustion engine was run and the fluctuations in performance, combustion and emission characteristics were investigated. Out of the four retarded injection timing retardations, the engine registered 29.6% brake thermal efficiency, 0.213 kg/kW of specific fuel consumption, 203 °C exhaust gas temperature, 42.4 bar peak cylinder pressure and reduced emissions such as oxides of nitrogen, unburnt hydrocarbons, carbon monoxide, carbon dioxide, smoke opacity at 18°CA.
