摘要： An automatic start-up system for a Rankine cycle engine provides start-up from a single actuation; for example, the closing of a switch. The start-up system initiates operation of a vapor generator for vaporizing working fluid which is admitted to an expander to produce work and a pumping system which supplies working fluid in the liquid state to the vapor generator. When the vaporized working fluid from the vapor generator begins to operate the expander at a predetermined running speed, the startup system is deenergized to terminate start-up operation. The engine then continues in a running mode. The engine may have a valve between the vapor generator and the expander for controlling admission of vaporized working fluid to the expander. When such a valve is present, a control means responsive to an appropriate engine operating condition is provided for establishing the proper valve setting.
