A connecting rod is the part of a piston engine which connects the piston to the crankshaft. Together with the crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft.

How does a connecting rod bend?
The most common causes of a bent connecting rod are detonation or over-revving. If you know you have been driving in deep water it could have flooded your engine, leading to hydro-lock which will easily bend your connecting rods.
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.
What holds 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.
How do you check a connecting rod bend?
One can check bend by using two pins and v block. In this method, two pins with exactly same diameter of pin bore and crank bore are used. Length of pins should be longer than the width of connecting rod and both the pins should be of same length. Connecting rod is rested on v block.
Why connect rods break?
Fatigue. Fatigue is the main cause of broken connecting rods--especially in older engines. The constant compression during the power stroke and stretching during the exhaust stroke, over thousands of times a minute, eventually wears the metal out and it becomes brittle and finally breaks.
Why is steel used for connecting rod?
When it comes to drag racing and street performance, engine builders have made steel the material of choice in most applications. It used to be that high-rpm engines used aluminum or other exotic materials to give rods high strength and light weight.
Can you machine a connecting rod?
Manufacturers of connecting rods use CNC machining technology, involving several operations to create batches of connecting rods for multiple engine types. Typically, a combination of various forms of gauging are used alongside the machine to monitor connecting rod quality and allow engineers to correct the process.
Is connecting rod and piston rod the same thing?
In a piston engine, a piston rod joins a piston to the crosshead and thus to the connecting rod that drives the crankshaft or (for steam locomotives) the driving wheels. ... The term piston rod has been used as a synonym for 'connecting rod' in the context of these engines.
What is a connecting rod journal?
The connecting rod journals are offset from the axis of rotation, and are attached to the big ends of the pistons' connecting rods. Confusingly, they are commonly also called crank pins or rod bearing journals . A feed of pressurised oil comes through an angled oil passage drilled from the main journal.
Which force is experienced by connecting rod?
Which force is experienced by connecting rod? Explanation: The connecting rod is subjected to the force of gas pressure and the inertia force of the reciprocating part. Hence, the Inertia force is the right answer.
Where is the connecting rod located?
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 is the crankshaft connected to?
The crankshaft is connected to the fly-wheel (used to smooth out shock and convert energy to torque), the engine block, using bearings on the main journals, and to the pistons via their respective con-rods.
Can a starter bend a connecting rod?
The starter does not have enough torque to bend a rod. Location: Uno, Pa. Any liquid can bend a rod since it can't be compressed, but we're talking about introducing that liquid into the cylinder at running speeds; a starter won't do it.
How do you measure a connecting rod?
A Connecting Rod is measured between the centers of the crankshaft journal bore and the piston pin bore. It can be listed in inches or millimeters. The connecting rod's length will impact Rod Ratio . Also, changing the rod length will require new pistons with the correct Compression Height .
