Title
(EN) ENGINE WITH AT LEAST ONE OF NON-SINUSOIDAL MOTION AND EMBEDDED PISTONS
(FR) MOTEUR AVEC AU MOINS UN MOUVEMENT NON SINUSOÏDAL ET DES PISTONS INTÉGRÉS
Abstract
(EN)
Various embodiments are described herein for methods and devices that relate to a drive mechanism, and a power mechanism that can be used 5 individually or together in an engine to obtain increased efficiency are provided according to the teachings herein. The embodiments described herein generally employ at least one of drive mechanisms that provide for non-sinusoidal motion and embedded piston arrangements.
(FR)
Divers modes de réalisation selon l'invention concernent des procédés et des dispositifs qui se rapportent à un mécanisme d'entraînement, et à un mécanisme d'alimentation qui peut être utilisé 5 individuellement ou conjointement dans un moteur pour obtenir une efficacité accrue. Les modes de réalisation de la présente invention utilisent généralement au moins l'un des mécanismes d'entraînement qui assurent un mouvement non sinusoïdal et des agencements de pistons intégrés.
