Abstract

The piston and cylinder assembly are the well known components of I. C. Engines where friction  and  wear losses occurs.  The present work attempt to evaluate the friction and wear behavior at the piston ring liner assembly as it is the major contributor of the piston assembly friction by changing different materials. Normally  now  a  day  most  probably  cast  iron  and stainless steel are used for manufacturing piston ring and grey cast iron, aluminium alloy and stainless steel for cylinder liners in the market. Total Friction losses are estimated approximately about 17-18% in various parts of engines i.e. crank, bearings, piston  cylinder valves, pumps, connecting rod etc. The PRA (Piston Ring Assembly)   contributes   about   35-45%   of   the   total frictional losses in the engine. So it is required to understand the behavior of friction and wear of PRA in Internal Combustion Engine. This types of losses is measure by the using the machine which is known as (LRT) Linear Reciprocating Tribometer. Comparative study  of  various  combinations  of  piston  rings  and cylinder  liners  material  would  help  us  understand  the best combination of PRA in an I. C. Engine under fully flooded\  hydrodynamic  lubrication  with  15W40 lubricant.
