About Automotive Connecting Rod

A connecting rod is a critical component in an internal combustion engine (ICE) that links the piston to the crankshaft. It converts the reciprocating motion of the piston into the rotational motion of the crankshaft, transmitting the engine's power. Connecting rods are typically made of steel, aluminum, or titanium, and are strong enough to withstand the high forces they experience while also being lightweight to minimise engine vibrations.

Properties of Automotive Connecting Rod

Automotive connecting rods are typically made from forged steel, which provides high strength and durability. Forged connecting rods have a better strength-to-weight ratio compared to cast or sintered rods. They are designed to withstand high compressive, tensile, and shear stresses during engine operation. Other materials used for connecting rods include carbon steel, iron-based sintered metal, micro-alloyed steel, and spheroidized graphite cast iron. In high-performance automotives, rods made with lightweight materials like aluminum alloys or titanium are also used to reduce weight and improve efficiency.

Manufacturing Process of Automotive Connecting Rod

The manufacturing of automotive connecting rods begins with forging a blank from steel, where it is heated and then pressed between two dies using a high-force press. This shapes the blank into the rough form of the connecting rod, with excess material trimmed off. The forged part is then shot peened, which involves bombarding the surface with small metal shot. This cold working process increases the fatigue life of the connecting rod by inducing beneficial compressive stresses.

Next, the forged connecting rod undergoes a series of machining operations on a CNC mill to achieve the final precise dimensions. Oil holes are drilled and bearing surfaces are honed to the proper finish. The connecting rod is then split into the big end and small end through a process called fracture splitting. Finally, the big end cap is aligned and attached to the rod using bolts. A thorough inspection is performed on the fully assembled connecting rod before it is shipped to the engine assembly line.

Production of Automotive Connecting Rod

The primary materials used for making connecting rods are steel, aluminum, and titanium. Steel is the most common due to its strength and durability, while aluminum is used for its lightweight properties. Titanium, though expensive, is used in high-performance applications for its superior strength-to-weight ratio.

Forging

Forging is the most common method used to manufacture connecting rods. It involves heating the metal and then shaping it using compressive forces. This process enhances the strength and fatigue resistance of the material.

Step 1: Heating

The selected metal (e.g., steel) is heated in a furnace to a temperature suitable for forging, typically around 1200°C for steel.

No significant chemical reactions occur during the heating phase, but oxidation can occur on the metal surface:  4Fe (s) + 3O2 (g) → 2Fe2O3 (s)

Step 2: Forging and Shaping

The heated metal is placed in a die and shaped into the connecting rod using a forging press. The compressive forces help to align the grain structure of the metal, improving its mechanical properties.

Heat Treatment

After forging, the connecting rod undergoes heat treatment to enhance its mechanical properties such as hardness, strength, and toughness. This process typically involves quenching and tempering.

Step 1: Quenching

The forged connecting rod is rapidly cooled in a quenching medium (water or oil) to form martensite, a hard and brittle phase of steel.

The phase transformation in steel:  Austenite (γ-Fe, FCC) → Martensite (α'-Fe, BCT)

Step 2: Tempering

The quenched connecting rod is reheated to a lower temperature (150-650°C) and then cooled to reduce brittleness and achieve the desired mechanical properties.

Tempering causes the transformation of martensite to temper martensite:

Martensite (α'-Fe, BCT) → Tempered Martensite (α-Fe, BCC) + Fe3C (cementite)

Machining

The heat-treated connecting rod undergoes precision machining to achieve the final dimensions and surface finish. This includes drilling the holes for the piston pin and crankshaft journal and finishing the surfaces to meet the required specifications.

Surface Treatment

To improve wear resistance and fatigue life, the connecting rod may undergo surface treatments such as shot peening or nitriding.

Shot Peening

Shot peening involves bombarding the surface of the connecting rod with small spherical media, creating compressive residual stresses that improve fatigue strength.

Nitriding

Nitriding is a surface hardening process where the connecting rod is exposed to nitrogen gas at high temperatures, forming a hard nitride layer on the surface.

2NH3 (g) → 2N (g) + 3H2 (g)

Fe (s) + N (g) → FeN (s) (Iron Nitride)

Each stage is essential to produce a connecting rod that meets the stringent requirements of strength, durability, and performance.

Applications and Drivers of Automotive Connecting Rod

Connecting rods are used passenger cars, motorcycles, commercial vehicles, and off-road vehicles. The increasing vehicle production in developing countries are fuelling the demand and sale for passenger and commercial vehicles, and thus connecting rods. For instance, in 2023, China's vehicle sales accelerated 12% to a record 30.09 million units and India's passenger vehicle sales breached the 4 million marks for the first time in 2023, leading to a corresponding increase in the demand for connecting rods. Advancements in manufacturing technology have also contributed to the growth of the connecting rod market as improved forging techniques allow to produce stronger connecting rods at lower costs. Finally, the replacement demand for connecting rods in vehicle maintenance and repair also contributes to the market growth.
