Abstract

Injecteur asservi. L'organe 3 commandant l'admission du carburant est conçu de façon à ouvrir lors de régimes peu élevés et lors de faibles charges du moteur d'abord un seul canal 6 ou une série de canaux et lors de régimes moyens ou en pleine charge un canal 9 ou une série de canaux d'injection supplémentaires. Moteurs à combustion interne et à injection directe
