Abstract:
A near adiabatic engine has four stages in a cycle: (1) a means of adiabatically expanding the working fluid during the downstroke from a high pressure/temperature level to a low level; (2) a means of cooling the working fluid at Bottom Dead Center (BDC); (3) a means of adiabatically compressing that fluid from a low pressure/temperature level at BDC to the higher level at Top Dead Center (TDC); and finally, (4) a means of passing that working fluid back to the high pressure/temperature source in a balanced pressure environment so as to minimize the resistance of that flow. This disclosure teaches the means of achieving (2) and (3) as follows: (2) a means is disclosed of BDC cooling of the expanded working fluid in the working chamber, and (3) a means is disclosed of adiabatically compressing the working fluid into the pump chamber before cycling the fluid.

Claim (Index 2):
An adiabatic cycle heat engine, comprising:\n a piston chamber; a power piston moveable within the piston chamber for running on working fluid fed by a high pressure state receivable from a heating exchanger; and a power piston moveable within the piston chamber, comprising:\n a means of balancing the quantity of said working fluid in said pump volume to be equal to the quantity of said working fluid that was initially injected into said piston chamber by balancing the density ratio between said pump volume and said cooling exchanger volume so as to maximize the isothermal heat absorption in said cooling exchanger and the adiabatic compression in the said pump volume; \n a means of controlling said quantity and said density in the said pump volume by sizing the internal volume of said cooling exchanger; \n a means of gaining additional time for heat absorption inside said cooling exchanger; and \n a means of momentarily increasing the volume inside said cooling exchanger during said compression of said fluid so as to gain additional time for heat removal during said containment of said fluid in said cooling exchanger before its said release.
