Abstract
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.
Claims13
A thermodynamic engine comprising:
- a thermodynamic expander for expanding a working fluid combined with a second fluid;
- a separator connected to an exhaust of the expander for separating second fluid from the working fluid;
- means for passing the second fluid to a heater to heat/reheat the second fluid, and then to a vaporising region;
- a condenser for condensing the working fluid from gaseous form to a volatile liquid form;
- and
- means for passing the condensed working fluid in liquid form to the vaporising region from a first collection tank to contact with the heated/reheated second fluid within the vaporising region to volatise the working fluid to produce work during expansion in the expander.
