Introduction to the process flow of automobile engine assembly line

The automobile engine is the heart of the automobile, and its manufacturing technology is the concentrated embodiment of the vehicle manufacturing technology. The process flow of automobile engine assembly line has a decisive influence on the product quality. Therefore, the automobile manufacturers in order to improve the assembly quality and production efficiency, we must analyze the whole process of automobile engine assembly line process.

The car engine assembly line throughout the process as follows:
