Abstract:
The engine efficacy require the blend of friction reduction approach to optimize the attained output. The research elucidates the scope of friction reduction mechanism to increase engine power and life. The engine components like the crank shaft, piston, piston rings, cam shaft, and tappet are coated with the unique composite of graphite layer which slides over each other to reduce friction and wear. The graphite coating on piston reduces direct contact between piston and cylinder liner, which reduces friction by 5% and lead to better thermal stability, and engine life. The friction between engine components reduces output power, and the engine oil temperature plays a big role in it. The research also focuses on friction reduction of camshaft bearing to 1% by replacing it with low friction roller bearing. The research empowers zirconium coating on oil sump so that the engine oil temperature can be retained for the longer time. The optimized engine oil temperature reduces viscosity and leads to friction reduction by 3%. The cars because of traffic gets on and off sporadically, where engine oil temperature roles become bigger, as optimized temperature reduces the problems caused by cooler engine oil which is more viscous and absorbs chamber warm up the temperature. The absorption of chamber temperature leads to extra combustion effecting BSFC. The variable flow of oil according to engine rpm reduces friction by 2%. In our research we have optimized engine power by reducing the weight of the piston, connecting rod and crankshaft, and are able to reduce friction by 0.5%. The crankshaft bearing diameter reduction reduces friction by 2.5%. The effect of different engine oils grading on friction have been elucidated. The research exploration reduces friction mean effective pressure by 14% and controls CO2 emissions by 8%. Keywords: Friction, Engine, Coating, Power, Zirconium
