Classification of automobile connecting rod

1.Diesel engine connecting rod

The connecting rod of the diesel engine bears high explosion pressure and low rotation speed. The strength shall be considered first, so the structural size is too large, the mass is large and the stiffness is good.

The connecting rod diagram and forging diagram of typical domestic diesel engines are shown in Figure 1 to figure 5.

2.Gasoline engine connecting rod

When designing gasoline engine connecting rod, especially high-speed gasoline engine connecting rod, because of its high speed and large inertia force, the connecting rod design requires light structure, light weight and good stiffness.

Typical domestic gasoline engine connecting rod diagram, as shown in Figure 6 and Figure 7.
