GRAND MOTEUR À COMBUSTION INTERNE À ALLUMAGE PAR COMPRESSION ET À DEUX TEMPS COMPORTANT UN SYSTÈME D'INJECTION DE CARBURANT À FAIBLE POINT D'INFLAMMABILITÉ ET SOUPAPE D'INJECTION DE CARBURANT ASSOCIÉE

摘要

A large two-stroke turbocharged compression-ignited internal combustion crosshead engine with a plurality of cylinders (1), at least one pressure booster (40) for each cylinder for boosting fuel pressure, two or more electronically controlled fuel valves (50) for each cylinder with an inlet of said two or more electronically controlled fuel valves (50) being connected to an outlet of said at least one pressure booster (40), an electronic control unit (25) operably connected to said at least one pressure booster (40) and said two or more electronically controlled fuel valves (50). The electronic control unit (25) is configured to: - determine a start time for a fuel injection event, - activate said at least one pressure booster ahead of the determined start time, - open the two or more electronically controlled fuel valves at the determined start time.
