本文介绍了一种超长行程的高速柴油机的设计与研制。该型发动机的原机是增压型。采用超长行程的主要目的是用增大排量的方法使发动机获取足够的动力以取代原机采用的增压系统。这样做不仅降低了发动机的制造成本 ,而且提高了使用可靠性。本文主要介绍了超长行程发动机的设计思想和研制过程中涉及到的一些重要环节。目前该机已投入正式生产。
This article describes the design and development of a long-stroke high-speed diesel engine. The original engine is supercharged type. The main purpose of using long travel is to increase the displacement of the engine to get enough power to replace the original machine using the booster system. Doing so not only reduces the manufacturing costs of the engine, but also improves the reliability of use. This article mainly introduces the design idea of long stroke engine and some important steps involved in the development process. The aircraft has been put into formal production.
