Bare Engine can also improve performance and efficiency, and reduce engine noise and vibration. This is because Bare Engine can reduce friction and wear inside the engine, thereby improving the engine's operating efficiency and stability.

The structure of an Mitsubishi Engine usually includes a crosshead connecting rod big end bearing and a connecting rod bolt. The crosshead connecting rod big end bearing is usually manufactured separately, while the big end bearing without a crosshead connecting rod is designed as an integrated design.

In addition, self-adjusting or platform connecting rod small end bearings are often used in the structure of Bare Engine to ensure the normal operation and stability of the engine.

In short, Bare Engine are a very important component in the Car Engine, which can effectively reduce the wear of the crankpin, improve the performance and efficiency of the engine, and reduce the noise and vibration of the engine.
