There is provided a biomass gas-fired engine 1 which can prevent start stall, reduce the frequency of maintenance work, and enhance the operational efficiency. Biomass gas is generated in a gasification furnace 2 and supplied to an engine 4 through a zero governor unit 3. The zero governor unit 3 is connected with an air supply path 32 for purging residual gas out of a zero governor 30 with air. After supply of the biomass gas from the gasification furnace 2 has ended, residual gas is purged out of the zero governor 30 with air. A control section 10 provides control for extending a normal operation time S1 of a starter motor 49 by a time S3 to recharge biomass gas in an amount corresponding to an amount of residual gas expelled by the air purge, only when the engine 4 is started for a first time FS after the gasification furnace 2 starts to supply the biomass gas. |
