A Microcomputer-Controlled System for Artificial Atmosphere in Underwater Heat Engines

研究了热动力ＡＩＰ系统在脱离大气条件下工作时，人造大气成分的在线检测与实时控制问题，提出了一种结构合理、工作可靠、控制质量好的数据采集与计算机过程控制系统．

he on-line measurement and real-time digital control of the artificial atmospheric composition in underwater heat engines are studied and a microcomputer-based data collecting and process control system has been developed. Gases are fed through the specially desigped and digitally controlled valves to a mixing chamber, and the compositions,the concentrations and the flow rates of the intake mixture are all under control. An experimental investigation with an indirect injection diesel engine under closed cycle operation shows that it is reliable in operation and capable of accurately supplying any arbitrarily specified concentration and flow rate.
