Abstract

L'invention concerne l'alimentation d'un moteur à combustion interne en carburant gazeux liquéfié. Elle se rapporte à un circuit d'alimentation en carburant gazeux liquéfié contenant au moins un composant principal. Le moteur à combustion interne est un moteur à injection (40) qui comporte au moins un injecteur (36) introduisant le carburant dans le circuit d'admission, et la canalisation (32) comporte, entre le réservoir et le moteur, une pompe (34) de carburant gazeux liquéfié destinée à mettre le carburant à une pression qui, pendant le fonctionnement, est constamment supérieure ou égale à la pression de vapeur du composant principal le plus volatil à la température la plus élevée atteinte par l'injecteur (36). Application aux moteurs à combustion interne.
