Yuchai Machine Qingdao Zhongke Yinghua Technology Research Institute is located in Chengyang District. It is an applied technology R&D institution jointly established by the Changchun Yinghua Institute of the Chinese Academy of Sciences and the Qingdao Municipal Government. It has now completed a series of tungsten aluminum alloy reinforced aluminum matrix composite materials (9 series aluminum alloy). 5000 tons/year industrialization project. Guangxi Yuchai Group is a large modern enterprise group that integrates the engine industry chain and the petrochemical industry chain. It has the most complete and complete internal combustion engine manufacturing base in China. The two sides jointly built an advanced auto parts R&D center to promote the transformation and upgrading of the industrial structure of China's auto industry, and actively responded to the national energy-saving and emission-reduction policies to achieve a lightweight vehicle. The R&D center will carry out research and development of advanced auto parts based on new materials and actively promote the industrialization of achievements, vehicle and engine accessories for new energy vehicles and new commercial vehicles, including knuckles, swing arms, connecting rods, crankshafts, pistons, etc. Design, experiment and production.
On the day of the completion of the Advanced Auto Parts R&D Center, the first joint development project between the two parties was initiated. The aluminum alloy connecting rod project of the diesel engine jointly developed by Qingdao Zhongke Yinghua Technology Research Institute and Guangxi Yulin Chengxin Machinery Co., Ltd. was launched. It is reported that the connecting rod is an important part of the engine to connect the piston and the crankshaft. It is subject to alternating load such as compression and tension, and must have sufficient fatigue strength and structural rigidity. The explosion pressure of diesel engines is high. At present, the connecting rods are all made of Steel, and ordinary aluminum alloys cannot meet the requirements for use. The 9 Series aluminum alloy of Qingdao Zhonghua Yinghua Technology Research Institute has high strength, high corrosion resistance and high temperature resistance, and its main performance has reached the world's cutting-edge level. The successful development of the 9-series high-strength aluminum alloy diesel engine connecting rod will be our country. A major breakthrough in engine research and development.
