ENGINE DRIVE SYSTEM AND SHIP

摘要

An engine drive system (10A) is provided with a two-stroke engine (2E) having a combustion chamber (20), and a tank (3) for storing natural gas in a liquid state. Natural gas accounting for some of the amount of fuel needed for a single combustion is injected at low pressure from fuel gas injection mechanisms (41) into the combustion chamber (20), and fuel oil accounting for the remainder of the amount of fuel needed for a single combustion is injected at high pressure from fuel oil injection mechanisms (42). Natural gas that has gasified in the tank (3) is guided to the fuel gas injection mechanisms (41) by a supply channel (6).
