Dhruv S. Joshi, Amit V. Shah, Dipak C. Gosai - Importance of Tribology in Internal Combustion Engine: A Review

Article. — International Research Journal of Engineering and Technology. — 2015. — Volume 2. — P. 803-809Abstract: This paper presents studies related to engine tribology in internal combustion engine. Friction loss is the main portion (48%) of the energy consumption developed in an engine. Lubricants are used to reduce the friction and wear and fuel consumption, increased power output of the engine, reduced oil consumption, a reduction in exhaust emissions in the engine. From the Analysis of the tribologist this means increasing specific loads, speeds and temperatures for the major frictional components of the engine, namely, the piston assembly, the valve train and the journal bearings, and lower viscosity engine oils with which to lubricate them. The literatures revealed that the most important parameter in the engine is lubricant, speed and load and with help of many different methods like blending the engine oil, remove the compression ring , additives are added to engine oil and analysis of piston ring assembly it can get the control on to the friction and wear and achieve almost all the objective that mention above.
