What is a connecting rod in an engine?

The con-rod connects the piston to the crankshaft to transfer combustion pressure to the crankpin. There are bearing portions at both ends, the piston side is called the small end, and the crankshaft side, the big end.

What are the parts of connecting rod?

Following are the parts of connecting rod:

Small End.
Big End.
Bushing.
Bearing inserts.
Bolt and Nut.
Shank.
Wrist pin.
Piston.

Where are the connecting rods located in an engine?

The connecting rod is mounted on the crank pin of the crankshaft with a plain bearing. The connecting rod bearing cap is bolted to the big end. In most cases the connecting rod is hollow or provided with an internal cast oil duct to supply the gudgeon pin with lubricant.

What connects the piston rod to the connecting rod?

The piston is attached to the connecting rod by a short hollow tube called a wrist pin , or gudgeon pin . This wrist pin carries the full force of combustion. The piston is not only subject to vertical forces during combustion, but also side forces caused by the continuously changing angle of the connecting rod.

What is the material of the connecting rod *?

The materials used for connecting rods widely vary, including carbon steel, iron base sintered metal, micro-alloyed steel, spheroidized graphite cast iron. In mass-produced automotive engines, the connecting rods are most usually made of steel.

Which material is used for connecting rod?

Which process is used for connecting rod?

The current manufacturing processes for connecting rods by fracture split drop forging and fracture split powder forging are highlighted and compared based on current information. A connecting rod in a high performance engine is subjected to inertial forces and bearing loads.

Which material is best for connecting rods?

Steel is normally used for construction of automobile connecting rods because of its strength, durability, and lower cost.

What causes connecting rod failure?

Common causes of connecting rod failure are tensile failure from high engine speeds, the impact force when the piston hits a valve (due to a valvetrain problem), rod bearing failure (usually due to a lubrication problem), or incorrect installation of the connecting rod.

What is the function of a connecting rod in an engine?

A connecting rod basically connects the piston to the crankshaft whilst transmitting power of the combustion from the combustion chamber to rotate the crank. It may be made of carbon steel or any other alloy.

What software do you use to model the connecting rod?

A parametric model of Connecting rod is modeled using CATIA V5 R19 software and to that model, analysis is carried out by using ANSYS 13.0 Software. Finite element analysis of connecting rod is done by considering the materials, viz… Forged steel.

Why are connecting rods made of powder metal?

Recent engines such as the Ford 4.6 liter engine and the Chrysler 2.0 liter engine have connecting rods made using powder metallurgy, which allows more precise control of size and weight with less machining and less excess mass to be machined off for balancing.

How do I find the forging number on a connecting rod?

Certain connecting rods do not carry a forging number. Identification may be possible from insignias, paint marks or other markings located on the connecting rod. Reference the comments in the Alphabetical Listing by Manufacturer section of this manual for these marks.
