Abstract

L'invention concerne un moteur à pistons libres qui est relié à un précompresseur (14) et à une turbine (16) de telle sorte qu'un gaz comprimé puisse circuler entre ledit moteur et ces éléments. L'objectif de l'invention est de créer un moteur de ce type qui soit compact et léger, présente une faible consommation spécifique de carburant, se compose d'un nombre réduit de composants, garantisse une longue durée de vie et ne nécessite sensiblement pas de lubrification ni d'entretien. À cet effet, le moteur à pistons libres (18) selon l'invention présente au moins un piston (20) qui peut être soumis à un mouvement alternatif dans une chambre de cylindre et sépare cette chambre en deux chambres de combustion (36, 38) et le précompresseur peut être actionné électriquement et/ou de façon assistée par gaz d'échappement.
