Basic Concepts of Engine Connecting Rods

An engine connecting rod, often referred to as a con rod, is a pivotal element in the internal combustion engine. Its primary function is to convert the linear motion of the piston into rotational motion of the crankshaft. This conversion is fundamental to the engine’s operation, as it allows the energy produced by the combustion of fuel to be harnessed and used to propel the vehicle ¹.

Purpose of the Cummins 3013930 Engine Connecting Rod

The Cummins 3013930 Engine Connecting Rod plays a role in the operation of a truck engine by transferring motion from the piston to the crankshaft. As the piston moves up and down within the cylinder, the connecting rod translates this linear motion into rotational motion, which drives the crankshaft. This continuous motion is essential for the engine’s operation, enabling it to generate power efficiently ².
