摘　　要：介绍了两种385气缸体的结构特点,分析了气缸体常用的传统铸造工艺方案的不足及两种385气缸体采用一箱一件生产方案成本高的缺点,较详细地阐述了两种385气缸体一箱两件生产方案的特点及应用工艺研究所获得的新技术使铸件最终合格率达到85%以上。Construction porticulars of two types 385 engine blocks are introdcted. The shortcomings of often used traditional casting project for engine blocks and high production cost for two types of 385 engine blocks under casting condition of one flask one casting are analyzed. Production features of two types 385 engine blocks under condition of one flask-two castings are described in detail. The application of such new technique developed through investigation brings about final qualified casting rate higher than 85%.
