A Study Of Process Design And Production Capacity About 4G9 Engine Based On The Cycle Time

Our country's auto industry has been rapidly development since the 90s of the 20th century. Engine, as the car's heart, has a great impact on the development of automotive industry. A reasonable process for 4G9 engine is designed and the problem that how to improve the productivity of enterprises without a substantial increase in costs is studied in this paper.Firstly, the factors considered in design cycle process is analyzed and the method of calculating cycle time is introduced, then the cycle time of the 4G9 engine,187.2 seconds, is calculated according to the formula. Secondly, this paper analyzes the factors that affect the 4G9 engine process by the method of survey and the method which combines both qualitative analysis and quantitative analysis. Then the process of 4G9 engine is designed based on the cycle time. Then, the concept of capacity and methods of concurrent processes are introduced in this paper and the factors that affect the concurrent processes of 4G9 engine process are analyses, then the process of 4G9 engine is adjusted and the productivity effects after adjustment is analyzed. Finally, some safeguards of 4G9 engine production capacity are derived and it's the first time that drives sustainability and mutability of cycle time is derived.By the studying of the capacity of 4G9 engine.this paper explores the solutions of production line balancing and the practical ways of improving productivity, and the production process is optimized in this paper, and by this paper, the study area about production process of engine is enrich. The data of this paper comes from actual research, the methods used and the conclusions derived in this paper have practical significance in engine design and production capacity.
