In a gas engine 1 that uses a gas having a lower specific gravity than air and has a pre-mixing device before a turbocharger, a pre-mixed gas mixture compressed by a turbocharger 3 is cooled by an intercooler 4 located downstream of the turbocharger 3 in the intake system. Condensed water produced as the gas is cooled and the pre-mixed gas mixture discharged with the condensed water are separated into condensed water, air, and fuel gas in a vapor-liquid separator 7. The fuel gas is returned to the intake system upstream of the turbocharger 3, while the condensed water is discharged to atmosphere. |
