After years of technological innovation and accumulation, the company has formed a set of flexible engine parts production technology with independent intellectual property rights. The company and its subsidiaries own and share more than 50 patents. The company's technology research and development is mainly based on independent research and development, and has successfully developed multiple complete core technology systems, which have been successfully applied in large-scale production. For example, for the cylinder head of engine parts, the company has successfully developed a variety of flexible production lines for cylinder heads, and developed various types of CNC processing modules for flexible automatic lines. When the flexible automatic line is transformed from one of the types of processing variants to processing In the case of another kind of workpiece, the CNC program can be changed to adapt to variable and multi-variety processing, which greatly improves production efficiency and equipment utilization. This production line can also be borrowed when developing similar products, which greatly improves the development speed. For engine parts and cylinder blocks, the company has successfully developed the offset design technology for cylinder bores and crankshafts. The offset and misalignment layout design of cylinder bores and crankshafts reduces the side pressure and friction of the pistons, and extends the length of the cylinder liners and pistons. The service life reduces the subsequent maintenance cost of the engine; on the other hand, it saves the space of the crankshaft and piston movement, reduces the size of the engine, saves the installation space of the vehicle, and reduces the loss of transmission power. In addition, for connecting rods, flywheel housings, main bearing caps, gear chambers, exhaust pipes and other products, the company has respectively mastered the expansion and vibration chip removal device technology and the small head bushing hot pressing technology, automatic centering expansion fixture, Core technology systems such as tile groove error-proofing device, permanent magnet non-deformation device, and nozzle vertical plus car device.
