FUEL SUPPLY UNIT

摘要

A fuel supply unit including injectors to adjust a flow rate and a pressure of fuel gas and an outflow passage of which the fuel gas injected from the injectors will flow out, wherein the fuel supply unit further includes: a branch passage that branches off from the outflow passage and communicates with an injection port of the injector; a specified injector defined as N−1 or less pieces of the injectors when N pieces of the injectors are provided, in which N denotes an integer more than 1; and a pressure reduction member provided in the branch passage that communicates with an injection port of the specified injector, only the specified injector is operated during idling, and the pressure reduction member is configured to decompress injection pressure of the fuel gas which will be injected from the specified injector.
