ピストンの信頼性とコスト改善を狙った最適化

抄録

The demand of passenger cars equipped with small direct injecting diesel engines is rapidly increasing because such engines have high heat efficiency and low carbon dioxide emisson. To improve the durability of piston performance, it is important to stabilize and lower the temperature of the piston lip. In this study, parameter design was conducted to find the optimum condition for durability improvement followed by tolerance design for cost reduction.
