(FR) SOUPAPE D'ADMISSION DE GAZ ACTIONNÉE PAR CAME AVEC COMMANDE DE COMPENSATION ÉLECTRO-HYDRAULIQUE
Abstract
(EN)
A gas engine is disclosed. The gas engine may include a combustion cylinder. The combustion cylinder may include an intake with an intake valve. The combustion cylinder may include an exhaust with an exhaust valve. The gas engine may include a gas admission valve assembly coupled to the intake. The gas admission assembly may include a trimmable electro-hydraulically actuatable gas admission valve to control a gas flow into the intake.
