Abstract

A high efficiency reciprocating engine, nominally of the internal combustion type but alternatively of the external combustion type is disclosed. The new engine uses Hypocycloidal and alternatively Epicycloidal gear mechanisms to create differentiated compression and expansion ratios which then promote significant improvements in efficiency through lower compression losses and higher extraction of available energy. Through suitable augmentation, the engines can be made to provide higher power when needed over higher efficiency. Additionally, other parameter modifications enable realization of low side wall loads and true zero exhaust volume.
