【Abstract】 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.更多还原
