Abstract
An efficient thermal engine is disclosed. In some embodiments, a remainder of energy remaining after an expansion cycle is used to power a subsequent compression cycle. In other embodiments, novel configurations for a larger expansion volume than compression volume are provided. In addition, work of compression may be reduced in a compression cycle, and recovered in an expansion cycle.
