Parameters influencing connecting rod: A Review [ ]


Connecting rod works as an intermediate link between piston and crankshaft. The function of connecting rod is to convert reciprocating motion into rotary motion. Since it is subjected to variable tensile and compressive load, it should be strong enough to bear that load. Manufacturing of connecting rod is one of the most important parameter that can affect the overall performance of connecting rod. Selection of connecting rod for good performance of engine is very difficult. There are various factors that are to be considered before selecting connecting rod, like type of engine, maximum rpm engine produces, requirement of relative weight, stiffness and strength of connecting rods, type of cross section like I-section, H-section, Rectangular or circular, material of connecting rod etc. After selecting the appropriate cross section, the material used in the connecting rod should be chosen wisely because during manufacturing process it has to undergo various production processes and subsequent heat treatment process, which is very much important for strength and stiffness. In this paper, a review has been attempted on selection parameter of connecting rod like cross section, manufacturing process and material selection which can enhance the performance of engine.
