PROBLEM TO BE SOLVED: To provide a gas engine capable of reducing throttle loss. SOLUTION: First and second fuel gas supply pipes 111 and 112 to which first and second flow rate control valves 81 and 82 are respectively attached are connected to first and second fuel gas tanks 71 and 72 for respectively storing hydrogen gas and methane gas. A mixed fuel gas supply pipe 113 wherein the first and the second fuel gas supply pipes are aggregated are connected to a mixer 20, the mixed fuel gas wherein first fuel gas and second fuel gas are mixed is mixed with air flowing from an air cleaner 10 in the mixer. The mixture is pressurized by a turbocharger 30, cooled by a cooler 40, and is supplied to the engine 50. A controller 90 adjusts the opening of the first and the second flow rate control valves, and controls a mixing ratio of the hydrogen gas and the methane gas. For example, the ratio of the hydrogen gas is increased at low load, and the ratio of the hydrogen gas is reduced at high load. COPYRIGHT: (C)2004,JPO&NCIPI
