发动机制造厂,特别是重型柴油机厂,常由于受产量的限制不能采用最先进的工艺;但零部件专业厂,由于可以供给几个发动机和汽车制造厂的新机零件和维修配件,其产量可以成倍地增加,往往可以采用最现代化的工艺。这样,它们的产品可以质高,价低;专业厂还必需有研究机构和设施以不断改进它们的产品和工艺。本文作者基于以上观点,论述发动机的生产形式专业化问题,还叙述了铸造、锻造、冲压等工厂和加工厂在发动机制造中的作用。最后对发动机标准化系列问题提出建议。 Engine manufacturers, especially heavy-duty diesel engines, are often unable to adopt the most advanced technologies due to production constraints; however, parts and components specialists can produce new engine parts and maintenance parts for several engines and automobile manufacturers. Multiplied, often the most modern process can be used. In this way, their products can be of high quality and low prices; specialized plants also need to have research institutions and facilities to continuously improve their products and processes. Based on the above points of view, the author of this article discusses the issue of specialization in the production of engines, and also describes the role of casting and forging and stamping factories and processing plants in the manufacture of engines. Finally, it proposes a series of engine standardization issues.
