Why Serration in Connecting Rod?

connecting-rod cap on the rod, serrations also form very strong buttresses against the inertia-force components acting tangentially to the split line of the rods. Many obliquely split connecting rods are therefore provided with serrated joint faces, especially those which may be subjected to large inertia forces.

What is Ovality of connecting rod?

Check the ovality of the connecting rod: Check the ovality of the connecting rod by tightening both parts at its rated torque. Inside micrometer is used to determine the correct and current ovality of the connecting rod. If the ovality is out of limits, the connecting rod is not to be reused.

Why is I section used in connecting rod design?

The I-section of the connecting rod is used due to its lightness and to keep the inertia forces as low as possible. It can also withstand high gas pressure. 2. Sometimes a connecting rod may have rectangular section.
