Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of engine connecting rod, specifically to a motorcycle engine connecting rod with good heat insulation. BACKGROUND
[0002] In the motorcycle engine, the connecting rod is a key transmission component. Its small end is connected with the piston, and the large end is connected with the crankshaft. When the piston makes reciprocating linear motion in the cylinder, the connecting rod converts this movement into the rotating movement of the crankshaft. This conversion process enables the engine to continuously and stably output power, providing the necessary driving force for the motorcycle to run.
[0003] The engine connecting rod in the prior art adopts a solid structure design and does not have heat insulation effect. The existing engine connecting rod has poor heat insulation, and the heat generated by the combustion of gasoline inside the engine is transmitted to the outside of the engine through the connecting rod, which not only reduces the thermal efficiency of the engine, but also makes the surface temperature of the motorcycle engine too high, affecting the use comfort of the driver.
[0004] Therefore, we propose a motorcycle engine connecting rod with good heat insulation. CONTENT OF THE UTILITY MODEL
