Abstract

Appareil d'analyse. Il comprend un dispositif de contrôle pour l'application d'un programme d'essai à des organes d'alimentation en carburant, qui est ajusté par rapport à la puissance nominale du moteur considéré et le poids du véhicule dans lequel il est monté de telle sorte que les variations d'accélération du moteur soient contrôlées de manière à correspondre pratiquement aux variations de vitesse du véhicule admises suivant le programme. Application aux véhicules automobiles
