Optimization of Lemon Shape Big End Profile Connecting Rod under Engine Operation in Elastohydrodynamic Regime 2014-36-0309

Nowadays, due to the emissions regulations and customer requirements for more economic vehicles there is a demand of more efficient Internal Combustion Engine (ICE). The hydrodynamic bearings play an important rule converting the piston reciprocating displacement into a rotational motion. Thus, considering the sliding bearings vital to define the engine life and also responsible for part of friction loss inside the engine, it is important to optimize its profile and consequently tribological performance parameters which impact on fuel consumption. All in all, this work shows the analysis between lemon shape big end bearing and cylindrical one, in order to evaluate the advantages and disadvantages related to this micro profile.
