Abstract
Un injecteur de carburant (62) comprend un bras d’alimentation en carburant (64) et une tête d’injecteur de carburant (66) et la tête d’injecteur de carburant (66) a un passage de carburant (84). Le bras d’alimentation en carburant (64) a un passage d’alimentation en carburant (70) en communication fluidique avec le passage de carburant (84) dans la tête d’injecteur de carburant (66). Un premier guide de lumière (110) s’étend à travers le bras d’alimentation en carburant (64) et a une extrémité distale (112) agencée pour diriger la lumière dans le passage de carburant (84) dans la tête d’injecteur de carburant (66). Une source de lumière (120) est agencée pour fournir de la lumière dans une extrémité proximale (118) du premier guide de lumière (110). Un deuxième guide de lumière (114) s’étend à travers le bras d’alimentation en carburant (64) et a une extrémité distale (116) agencée pour recevoir la lumière transmise dans le passage de carburant (84) dans la tête d’injecteur de carburant (66) et un récepteur de lumière (124) est agencé pour collecter la lumière au niveau d’une extrémité proximale (122) du deuxième guide de lumière (114).
