Description

Technical Field

[0001] This utility model relates to the field of engine connecting rod technology, specifically to an engine connecting rod with a rapid cooling structure. Background Technology

[0002] In automobile operation, the engine provides power, converting the reciprocating motion of the piston into rotational motion of the crankshaft via connecting rods. The crankshaft's rotation outputs torque to drive the flywheel. The connecting rod's function is to transmit the force on the piston to the crankshaft and convert the piston's reciprocating motion into the crankshaft's rotational motion. However, existing engine connecting rods heat up during engine operation due to friction with the piston and crankshaft, as well as heat generated by combustion. High temperatures reduce the strength of the connecting rod material, making it more prone to deformation or even breakage under normal operating loads. Furthermore, repeated thermal cycles and high temperatures accelerate fatigue damage to the connecting rod material, significantly shortening its fatigue life. Traditional engine connecting rods can only dissipate heat through natural cooling, resulting in low cooling efficiency and difficulty in achieving rapid heat dissipation during use. This makes the connecting rod prone to prolonged high temperatures, leading to a short service life. Therefore, we propose an engine connecting rod with a rapid cooling structure.
