Abstract
A fuel feed device for a gas engine includes a thermally insulated cartridge case for receiving therein a disposable gas cylinder or cartridge. The cartridge case has a built-in temperature sensor for detecting the temperature of the gas cartridge, and a built-in electric heater for heating the gas cartridge. The electric heater is controlled such that the temperature detected by the temperature sensor is kept within a predetermined temperature range. A working machine driven by the gas engine is also disclosed.
