Abstract

L'invention concerne un ensemble d'un piston et d'un cylindre à système de refroidissement limite pour moteurs à combustion interne. Le piston comporte un système de refroidissement interne, son fond étant isolé pour limiter la transmission de chaleur de la zone de combustion au piston et par son intermédiaire au segment et à la paroi du cylindre. Les canaux de refroidissement de la paroi du cylindre sont alors limités à la région qui entoure la zone de combustion. L'huile lubrifiante peut être utilisée comme agent de refroidissement du piston qui l'atteint par l'intermédiaire de canaux ménagés dans la bielle. Application aux moteurs à combustion interne.
