Le groupe technologique W\u00e4rtsil\u00e4 a annonc\u00e9 une augmentation de la puissance de son moteur \u00e0 4 temps fonctionnant au carburant ammoniac. Cette am\u00e9lioration porte la puissance du moteur \u00e0 ammoniac „W\u00e4rtsil\u00e4 25“ \u00e0 315 kW par cylindre \u00e0 900 tr\/min et \u00e0 345 kW par cylindre \u00e0 1 000 tr\/min, selon l’entreprise. Ainsi, le moteur atteint le niveau de performance du moteur „W\u00e4rtsil\u00e4 25DF“ fonctionnant au GNL. Un avantage central de ce d\u00e9veloppement est la r\u00e9duction du nombre de cylindres n\u00e9cessaires tout en maintenant les besoins de puissance. Cela conduit, selon les informations du fabricant, \u00e0 une installation et \u00e0 une maintenance simplifi\u00e9es.<\/p>\n

Flexibilit\u00e9 dans le choix du carburant<\/h3>\n

Le nouveau niveau de puissance du moteur \u00e0 ammoniac „W\u00e4rtsil\u00e4 25“, qui couvre une plage de 1,9 \u00e0 3,1 MW, convient \u00e0 diverses applications, tant en tant que moteur principal qu’en tant que moteur auxiliaire. L’adaptation au niveau de puissance du „W\u00e4rtsil\u00e4 25DF“ fonctionnant au GNL am\u00e9liore \u00e9galement la possibilit\u00e9 de r\u00e9trofit du moteur. Cela devrait offrir aux propri\u00e9taires de navires une plus grande flexibilit\u00e9 en mati\u00e8re de choix de carburant. L’augmentation de la puissance a \u00e9t\u00e9 test\u00e9e \u00e0 l’automne 2025 sous la supervision de repr\u00e9sentants des soci\u00e9t\u00e9s de classification.<\/p>\n
