摘要： An expander of the piston (2) and cylinder (3) type is inverted from normal orientation, with the crankshaft (4) upper most and the cylinder “head” (5) lower most. The cylinder head has a pair of liquid injectors (6, 7) oriented for respective liquids pentane and glycerine to be injected as mists into contact with each other at the bottom of the cylinder. The pentane is vaporised by transfer of latent heat to it from the glycerine. Respective injector valves (9, 10) from high pressure rails (11, 12) fed by pumps (14, 15) are provided. An exhaust valve (16) is opened by a cam (17) driven at crankshaft speed by a chain drive.

摘要： The engine has a thermodynamic expander (21) for extracting work from a vaporised working fluid (22) that is fed to a feed for it. There is also a condenser (26) downstream of the expander for condensing expanded vaporised working fluid that is exhausting from the expander. A liquid tank (28) is downstream from the condenser, and pump means (29) is located downstream from the liquid tank for pumping out condensed working fluid (38). Further, there is a means for heating (50) and at least partially vaporising working fluid pumped to it from the pump and feeding the heated working fluid to the expander. The heating means itself has at least one inlet for the working fluid pumped to it, and at least one output from which the working fluid is fed to the expander.
