The eighth place, Shandong Huayuan Laidong Internal Combustion Engine Co., Ltd., located in Yantai City, is a high-tech enterprise specializing in the development, design, and production of engines and their parts as a major domestic production base for small and medium-sized diesel engines.

The company was founded in 1943 and began researching the production of internal combustion engines in 1953. In April 2008, it merged into China Hengtian Group and became a member of Hengtian Group.

Ranked ninth is the Dalian Diesel Engine Factory of China FAW Automobile Group, which was founded in 1951. It is one of the earliest diesel engine manufacturers in my country.

Ranked tenth, Dongfeng Chaochai Power Co., Ltd. is a large-scale backbone enterprise integrating product development, production and sales of automotive diesel engines. It is the first research and development base for the production of high-speed automotive diesel engines in China. It is a pity, now Production has been discontinued. The reason for the suspension of Chaochai’s engine is that on the one hand, it has not been able to meet the needs of today’s society, on the other hand, the engine is prone to loopholes. This requires us to always pay attention to product quality. pregnancy
