Abstract
Piston en métal léger pour moteurs Diesel à chambre de turbulence. Ledit piston est Caractérisé par le fait que la distance entre le bord inférieur de la pièce annulaire rapportée de la chambre de turbulence et la surface du fond du piston, par rapport à la distance entre les surfaces principales du fond du piston et de la culasse, est augmentée de 0,15 à 0,7 % du diamètre du piston dans les régions situées latéralement au canal d'injection, en dehors des cavités de combustion, et qui sont recouvertes par ladite pièce annulaire. Applications aux moteurs Diesel.
