Diesel engines are widely used and occupy a relatively core position in the industry chain to which they belong. In the past ten years of development, a series of supporting enterprises have been formed in the diesel engine production industry. Many diesel engine enterprises have played the role of general contractors and assemblers, and some key components of diesel engines: crank connecting rod , Pistons, cylinder liners and cams have been handed over to professional companies for production. Specialized division of labor enables diesel engine manufacturers to concentrate their advantages and focus on the design and manufacture of diesel engines.

Diesel engines are mainly used in final supporting products. For example, high-power and high-speed diesel engines are mainly used for heavy-duty vehicles, large passenger cars, construction machinery, ships, and generator sets. Therefore, the development of the diesel engine industry depends to a large extent on the market conditions of the relevant end products.

In the field of agricultural diesel engines, the market growth of developing countries will make up for the market decline in developed countries. The rapid growth of the global population and the replacement of old equipment will have a greater demand for agricultural machinery. The global agricultural diesel engine market will show rapid growth. In the field of aero-engine, the engine industry is the core sub-sector of the aviation industry, and the future development prospects are very broad. Based on the above analysis of various fields, we believe that the global diesel engine will maintain a steady development rate of 8%.
