What are Connecting Rods

August 17th, 2015 Uncategorized

Connecting rod (also conrod) is a detail which connects piston to the crankshaft or crank and provides motion energy between them. Connecting rod with the crank converts reciprocating motion into rotating motion. Cylinder fires and the explosion pushes down on the piston which pushes down on the connection rod. Conrod makes the in turn and causes the rotation of a crankshaft.

Connecting Rods

For the first time connecting rods were used in 3rd century AD in the Roman Empire on the Hierapolis sawmill. Nowadays connecting rods are widely used in different types of internal combustion engines.

Types of Connecting Rods

There are three most common types of connecting rods today: steel, aluminum and titanium.

The first type is the most prevalent because of affordable price of steel. This rod’s type can withstand heavy loads without bending, twisting or snapping. But steel rods are very heavy that’s why they consume more power and increase rotating assembly’s stress.

Steel Connecting Rods

Aluminum rods are up to 40% lighter than steel ones. Apart from smaller weight this rod’s type decreases rotating assembly’s stress and consumes less power, so has a long lifespan. But aluminum rods are more expensive.

Titanium rods are the most powerful and the lightest ones. At the same time these rods are extremely expensive that’s why they are used only in expensive racing engines.

Connecting rods play a vital role in internal combustion engine that’s why their quality and material are quite important. CP Carrillo connecting rods & pistons have remarkable lifespan and high-quality standards that’s why they are well-known among professional racers and ordinary drivers.
