<P>PROBLEM TO BE SOLVED: To provide a gas-engine air supply device which supplies a mixture of outdoor air and an unpurified gas to a supercharger to be supercharged by the supercharger, can prevent start-up performance from degrading when starting a gas-engine in a cold state of the engine under a low ambient temperature, and removes impurities included in the unpurified gas so as to prevent the impurities from flowing into the engine. <P>SOLUTION: The gas-engine air supply device having the supercharger has a first intake passage through which the mixture of the outdoor air and the unpurified gas is introduced to the supercharger, and a second intake passage through which indoor air is introduced to the supercharger. In the first intake passage, a filter for removing solid impurities in the unpurified gas and a first damper capable of opening and closing the first intake passage on the downstream side of the filter are provided. In the second intake passage, a heater for heating the indoor air and a second damper capable of opening and closing the second intake passage on the downstream side of the heater are provided. A damper control device for controlling the opening degree of the first damper and of the second damper is provided. <P>COPYRIGHT: (C)2012,JPO&INPIT |
