Abstract

Le piston comporte une chambre de combustion dans laquelle est formé un tourbillon. L'injection est effectuée pendant que l'air suit une rotation. Il en résulte une amélioration de la puissance de la combustion (réduction de la pollution). De façon plus générale, la période de refoulement du combustible est adaptable aux paramètres du moteur.
