The engine efficacies require the blend of friction reduction approach for optimising the attained output. The research elucidates the scope of friction reduction mechanism to increase engine power and life. The engine components piston and piston rings are coated with the unique composite of graphite, molybdenum disulfide, tantalum layer to reduce friction and wear. The coating on piston minimizes direct contact between piston and cylinder liner, which reduces friction, BSFC and lead to better thermal stability, and engine life. The research also focuses on friction reduction of camshaft bearing by replacing sliding contact bearing with low friction roller bearing. The friction between engine components reduces output power, and the engine oil temperature plays a significant role in it. The research empowers zirconium dioxide coating on oil sump in order to reduce the temperature decay rate so that the optimized engine oil temperature of 100 °C can be retained for longer time.
