Abstract

La présente invention concerne un dispositif de contrôle d'un injecteur de carburant (10) ou d'une buse d'injection de carburant (10) d'un moteur à combustion interne. Ledit dispositif comporte une pompe (12) qui génère une pression d'injection et qui permet d'amener un fluide de contrôle, notamment du carburant, conservé dans un réservoir (13), à un injecteur de carburant (10) à contrôler ou une buse d'injection de carburant (10) à contrôler. L'injecteur de carburant (10) à contrôler ou la buse d'injection de carburant (10) à contrôler fait saillie dans une chambre de contrôle (11) ou est disposée dans une chambre de contrôle (11) et injecte le fluide de contrôle dans ladite chambre de contrôle (11). La chambre de contrôle (11) reçoit une bande de test (14) qui reçoit du fluide de contrôle, injecté par ledit injecteur de carburant (10) à contrôler ou ladite buse d'injection de carburant (10) à contrôler, sous la forme d'une géométrie d'injection évaluable.
