本文扼要讨论了在设计一台新型高增压中速柴油机时如何决定柴油机的冲程数问题。并试从性能、强度、使用以及增压系统和增压器等不同角度来进行分析和比较。设计一台新型高增压柴油机时,首先就碰到冲程数的选择问题。就中速高增压柴油机的现状而言,二冲程和四冲程这两种型式兼而有之。表l和表2为若干台国外中速高增压柴油机的主要性能参数。从表中可看出采用四冲程比较多。从发展的新机型来看,除个别外,也以采用四冲程
This article briefly discusses how to determine the stroke number of a diesel engine when designing a new high-pressure medium-pressure medium-speed diesel engine. And try from the performance, strength, use and supercharging system and turbocharger and other different angles to analyze and compare. When designing a new high-pressured diesel engine, you first encounter the choice of stroke number. In terms of the current status of medium-speed and high-pressure diesel engines, two types of two-stroke and four-stroke are combined. Table l and table 2 for a number of foreign medium speed high pressure diesel engine main performance parameters. It can be seen from the table using more four-stroke. From the development of new models, in addition to a few, but also to use four-stroke
