Brief Introduction of General Motors Wuhan Base and SAIC-GM Wuhan Engine Factory Assembly Line

Is SAIC-GM Wuhan base in Wuhan? Motor city? Jiangxia District is the fourth passenger car production base of SAIC-GM after Shanghai Jinqiao, Yantai Dongyue and Shenyang Beisheng. Since it was put into operation, many hot-selling cars have been produced, such as Buick Hideo (check the transaction price | model details) and Chevrolet Explorer. Today, the three-cylinder engine production line has just been started and put into production in Wuhan base. Buick Xinyinglang/Lang Yue /GL6? Core? It was born here. Compare to? Delivery room? Is the most suitable.

The general situation of engine factory is few, but the automation rate is extremely high. Can you hardly see that the engine factory of SAIC-GM Wuhan base is fully digital? Delivery room? This paper adopts the digital development mode of product and process synchronization, and applies Siemens PLM/PDM platform products to carry out digital three-dimensional design, digital virtual analysis and simulation, so as to realize the integrated management of product development and process development. At present, this factory is producing GM's new 1.3T/ 1.0T Ecotec twin-injection turbocharged engine and Buick Hideo/Lang Yue /GL6 engine.

This three-cylinder machine with 95% automation rate? Delivery room? Not only the industry-leading intelligent technology and sophisticated equipment are adopted, but also the workshop temperature is controlled all the year round under the HVAC intelligent control system, which can meet the requirements of engine processing parts? Grade (0.00 1mm) machining and assembly accuracy requirements. Moreover, its machining center adopts high-precision five-axis linkage technology, which can automatically complete the whole manufacturing process from feeding, machining, cleaning, testing, assembly, detection to final blanking. So the quality and quality of the three-cylinder engine born here are at the same excellent level.

The 1.0T engine code-named LJI adopts manifold double injection technology, intake and exhaust VVT variable valve timing technology, integrated exhaust manifold, double thermostat and small inertia turbine design, which has a good balance between fuel consumption and power performance.

The code name of 1.3T engine is LI6, which is similar to 1.0T engine in technology, but this engine has an additional balance shaft on the basis of 1.0T engine. We will mainly take it as an example to illustrate this factory visit. Both products were developed by GM to replace some of its existing naturally aspirated/turbocharged engines.

There are three production lines in the machining workshop of Wuhan Engine Factory, which process cylinder block, cylinder head and crankshaft respectively, as well as camshaft, piston and valve production lines.

In order to ensure zero defect production, the finished engine needs 100% cold start test. (That is, the engine is filled with oil, but not with fuel)

In the whole milling manufacturing process of three engine parts, aluminium scrap and iron filings are all decompressed in the factory, which can not only greatly improve the recycling rate of cooling liquid, but also reduce the pollution to the environment.
