Abstract

Selon l'invention, un dispositif de combustion à impulsions hautement résistant aux interférences comprend: un mécanisme de réglage par impulsion, une chambre de combustion (4) et un tuyau arrière (5). Le mécanisme de réglage par impulsion communique avec le tuyau arrière (5) par la chambre de combustion (4). Le mécanisme de réglage par impulsion comprend deux ensembles de réglage par impulsion. L'ensemble de réglage par impulsion comprend un dispositif de réglage par impulsion (1), une vanne (3) et un tuyau (2). La vanne (3) est disposée sur le tuyau (2). La vanne (3) est raccordée électriquement au dispositif de réglage par impulsion (1). Le dispositif de réglage par impulsion (1) comprend un module de réglage par impulsion. La vanne (3) disposée sur le tuyau (2) est commandée par le dispositif de réglage par impulsion (1), assurant ainsi une entrée stable du carburant et de l'air, ainsi qu'une combustion complète du carburant dans la chambre de combustion (4). Lorsqu'un commutateur est débranché, un circuit intégré dans le module de réglage par impulsion est forcé à se réinitialiser, ce qui améliore la résistance aux interférences et la fiabilité du dispositif.
