    摘要： It is an object to provide an engine device in which in the engine device, which employs various types of fuels, plural fuel pipes can compactly be disposed without being thermally affected by exhaust gas. In the engine device (21) of the invention of the present invention, a gas fuel pipe (41) that supplies gas fuel to a gas injector (98), a fuel oil pipe (42) that supplies liquid fuel to a main fuel injection valve (79) are disposed to be divided on both sides of a row of head covers (40) arranged in a line. In addition, in the engine device (21), an intake manifold (67) that supplies air taken in by a main combustion chamber toward an intake valve (80) extends in parallel to the row of head covers (40) in a cylinder block (25), and the fuel gas pipe (41) and the intake manifold (67) are arranged on the same side of the row of head covers (40).

    摘要： An engine (100) is operable in a premixed combustion system and a diffusion combustion system. The engine (100) includes a main fuel injection valve (79), a pilot fuel injection valve (82), a liquid fuel tank (33), a main fuel supply path (121), a pilot fuel supply path (122), a pilot fuel filter (141), a pilot fuel high-pressure pump (56), a pilot fuel tank (171), and a pilot fuel supply pump (173). The pilot fuel tank (171) stores pilot fuel sent from the pilot fuel high-pressure pump (56) and not injected by the pilot fuel injection valve (82). This pilot fuel is sent to an automatic backwash filter (174) and a pilot fuel filter (141) while not passing through the liquid fuel tank (33).

    摘要： An engine (21) includes a main fuel injection valve (79), a pilot fuel injection valve (82), a liquid fuel supply rail pipe (42), and a pilot fuel supply rail pipe (47). The main fuel injection valve (79) supplies liquid fuel from the liquid fuel supply rail pipe (42) to a combustion chamber (110) during combustion in a diffusion combustion system. The pilot fuel injection valve (82) supplies pilot fuel from the pilot fuel supply rail pipe (47) to the combustion chamber (110) in order to ignite gaseous fuel during combustion in a premixed combustion system. The liquid fuel supply rail pipe (42) is disposed at one side of an imaginary vertical plane (PI) including an axis of a crank shaft. The pilot fuel supply rail pipe (47) is disposed at the side of the imaginary vertical plane (PI) at which the liquid fuel supply rail pipe (42) is disposed.
