    摘要: A gas engine system includes: a gas engine; an exhaust pipe through which exhaust gas discharged from the gas engine flows; a turbocharger connected to the exhaust pipe; a catalyst that oxidizes uncombusted fuel gas in the exhaust gas of the gas engine; a temperature sensor configured to measure a temperature of the catalyst; a catalyst activating device configured to supply an activation promoting agent that promotes activation of the catalyst to a passage extending from the exhaust pipe to the catalyst; and an engine controller. The activation promoting agent contains a hydrocarbon that has a less activation energy value for a catalytic reaction catalyzed by the catalyst than the fuel gas of the gas engine.
