一、概述考虑到我国能源的发展前景和交通运输现代化发展的需要,过去主要从事柴油机研究的上海船用柴油机研究所从1980年开始编制了热气机的研究规划。这项规划的一个内容是设计一台7.5千瓦试验用热气机,以便从中吸取设计和制造方面的经验,并创造必要的条件对关键性的零部件开展理论和试验研究。 2R70热气机的结构型式为两缸、双活塞、单作用式,即构成四分之一Rinia型布置的一个动力单元。通过性能计算和分析、确定的主要参数是:
First, an overview Taking into account the development prospects of China’s energy and transportation modernization needs, in the past mainly engaged in diesel research Shanghai Marine Diesel Engine Research Institute from 1980 on the preparation of the research plan of the hot air machine. An element of the plan is the design of a 7.5 kilowatts trial heat machine to draw on design and manufacturing experience and to create the conditions necessary to conduct theoretical and experimental studies on critical components. The structure of the 2R70 is a two-cylinder, dual-piston, single acting, one-power unit that forms a quarter-inch Rinia arrangement. Through the performance calculation and analysis, the main parameters are:
