The Downstream Application Market of Diesel Engine Parts is Vast

1) Introduction to diesel engine parts manufacturing industry

Diesel engines are the models with the highest thermal efficiency, the best energy utilization, and the most energy-saving among all kinds of power machinery currently used in industrial applications. They have become popular in commercial vehicles, agricultural machinery, engineering machinery, ships, diesel locomotives, geological and oil drilling rigs, military, It is the main supporting power for general equipment, mobile and backup power stations and other equipment. There are many types of diesel engines. At present, the most commonly used classification is based on the number of cylinders and their uses: they are mainly divided into four categories according to the number of cylinders, namely single-cylinder diesel engines, small-bore multi-cylinder diesel engines, medium-bore multi-cylinder diesel engines and medium-low speed diesel engines. The latter two categories Usually called medium and heavy-duty diesel engines, they are the main direction of diesel engine development at present; according to their uses, they can be divided into two categories: marine diesel engines and vehicle diesel engines.

The diesel engine industry is a very important branch of the machinery industry. The development of the diesel engine industry has a very significant impact on industry, agriculture, transportation, national defense construction, and people’s lives. The diesel engine parts manufacturing industry is the upstream industry of the diesel engine industry and mainly involves the manufacturing of core parts such as diesel engine cylinder blocks, cylinder heads, pistons, crankshafts, connecting rods, and camshafts.

2) Characteristics of diesel engine parts manufacturing industry

Diesel engines are widely used and occupy a relatively core position in the industrial chain to which they belong. In the past ten years of development, the diesel engine manufacturing industry has formed a series of supporting companies. Many diesel engine companies play more of a role as assembly assemblers. Some key parts of the diesel engine: crank connecting rod, Pistons, cylinder liners, camshafts, etc. have been produced by professional companies. Specialized division of labor allows diesel engine manufacturers to focus more on their own advantages and focus on the design and manufacturing of diesel engines.

After years of development, my country’s diesel engine technology has made great progress, and the gap between the overall technical level of the industry and the world’s advanced technical level has gradually narrowed. Especially in recent years, under the guidance of the national strategy of introduction, digestion, absorption and re-innovation, leading companies in the industry have paid more and more attention to technological innovation and technology reserves, as well as the application of new technologies and processes. Domestic enterprises have increased their technological accumulation through the introduction, digestion and absorption of foreign diesel engine technologies, especially diesel engine energy-saving and emission reduction technologies, and the technical level of diesel engine products has also been continuously improved through absorption and re-innovation.

3) The downstream application market of diesel engine parts is vast

Since diesel engines are mainly used in final supporting products, diesel engine parts are widely used in industries such as trucks, buses, construction machinery, agricultural machinery, ships, railway diesel locomotives, stationary power and power generation equipment. The development of the diesel engine and parts industry is closely linked to the downstream industries. The development of the diesel engine parts manufacturing industry depends to a large extent on the market conditions of related end products.

According to statistics from the China Internal Combustion Engine Industry Association, my country’s total diesel engine sales in 2021 were 6.1084 million units (including 238,300 units for passenger vehicles, 2.9675 million units for commercial vehicles, 1.0481 million units for engineering machinery, 1.4648 million units for agricultural machinery, and 1.4648 million units for marine machinery. 40,200 units, 317,500 units for power generation, and 31,900 units for general use). In 2022, my country’s total diesel engine sales were 4,286,600 units (including 188,700 units for passenger vehicles, 1,670,100 units for commercial vehicles, and 837,200 units for engineering machinery. 1.2223 million units were used for agricultural machinery, 39,700 units were used for marine use, 311,700 units were used for power generation, and 16,900 units were used for general purpose). The main reason is that the sales of diesel engines for commercial vehicles dropped rapidly.
