Abstract

Un module dalimentation auxiliaire est fonctionnel pour fournir l'air prélevé à un système de véhicule. Une méthode comprend la déviation substantiellement de tout lair prélevé vers un échappement pendant une durée sélectionnée commençant à lallumage du module dalimentation auxiliaire. Après la durée sélectionnée, au moins une partie de l'air prélevé est dévié vers le système de véhicule.
