Types of Connecting Rod

 

connecting rods

The connecting rod is the connection between the piston and the crankshaft that transfers forces. Connecting rods must be strong enough to stay stiff under load while also being light sufficient to decrease inertia forces generated when the rod and piston stop, change direction and restart after each stroke.

Connecting rods are the most common type of internal combustion engine component used in automobiles. Between the pistons and the crankshaft, the connecting rods allow for fluid movement.

  • Forged

The manufacturing procedure for connecting rods determines their kind. Forging is used to make some of the connecting rods. Connecting rods of this sort are manufactured by pressing a grain of material into the form of the end. Steel alloy or aluminium may be used, depending on the desired qualities.

  • Cast Rods

Original equipment manufacturers choose cast rods because they can bear the strain of a stock engine and are less costly to produce. Cast connecting rods have a visible seam through the center that distinguishes them from forged counterparts. Above 450 horsepower and 6,000 rpm, never use cast rods.

  • Powdered Metal

Powdered metal connecting rods are another original equipment manufacturer's option. A powdered metal combination is pressed into a mould and heated to high temperatures to solidify the material. Minimal machining is required because the powdered metal rods are a completed product right out of the mould. These rods are less costly than steel connecting rods and are more durable than cast connecting rods.

  • Billet

Connecting rods made of billet are often used in high-end racing automobiles. Billet rods are lighter, stronger, and more durable than other varieties because they are machined from a single piece of steel or aluminium. Some billet rods include characteristics that prevent stress risers and allow the natural grain of the billet material to show through.

  •  Plain Type Rods

 The simple connecting rod is employed in inline and opposed engines. The connecting rod's large end is linked to the crankpin and has a bearing cover. At the end of the connecting rod, a bolt or stud secures the bearing cap. 

  • Fork and Blade Rods

V-twin motorcycle engines and V12 aviation engines both employ these sorts of connecting rods. A forked rod is split into two pieces at the large end of each pair of engine cylinders, and a blade rod is tapered from the opposite cylinder to fill the fork gap.

  • Master and Slave Rods  

Master-and-slave connecting rods are used in radial engines. The one piston in this design is a master rod with a direct connection to the crankshaft. Other pistons attach their connecting rods to the rings that encircle the master rod's edge.

The form of a connecting rod used to matter a lot more than it does now. What matters now is the material used to make a connecting rod and how it was built. To prevent harming your engine, you should always use authentic, high-quality connecting rods. This is especially true if you increase its performance.
