ピストンオイル保持機能を通したエンジン開発上流工程における品質工学の適用

抄録

Simulation by computer-aided engineering has been used since the 1980s to shorten development time and reduce the cost of prototyping in automobile engine development. The results have improved the initial quality of components,reduced the amount of redesign, and improved the efficiency of the development process. However, making the development process more efficient is not enough; the manufacturer must also provide products that meet customer expectations and are robust under use by various types of customers in various market environments. In the present study, quality engineering was therefore applied in the early development phase, the piston oil retention function was optimized, and the effect was confirmed in a prototype.
