PROBLEM TO BE SOLVED: To provide an engine device for multiple fuels, capable of being disposed in compact while preventing a plurality of fuel pipes from being thermally affected by an exhaust gas.SOLUTION: In an engine device 21, a gas fuel pipe 41 for supplying a gas fuel to a gas injector 98, and a liquid fuel pipe 42 for supplying a liquid fuel to a main fuel injection valve 79 are disposed while distributed at both sides of a head cover 40 row arranged in one row. A lubricant cooler 58 and a lubricant strainer 59 are arranged in series on one side face at a gas fuel pipe 41 side, of a cylinder block 25. A first cooling water pipe 60 for supplying cooling water to the lubricant cooler 58 is extended along the lubricant cooler 58 in a state of separating from one side face of the cylinder block 25 at a position between the gas fuel pipe 41 and the lubricant cooler 58. A second cooling water pipe 46 connected with the cylinder head 26, is extended in parallel with the head cover 40 row at a position between the head cover 40 and the gas fuel pipe 41. |
