ABSTRACT:
A fuel supply and glow plug arrangement for a portable electrical power supply fueled by a gaseous fuel internal combustion engine. The gaseous fuel flow to the engine is controlled by a solenoid valve having its duty cycle varied to vary engine speed. In addition, the solenoid valve is shut off when the engine speed falls below a predetermined speed so as to prevent fuel leakage. The engine is fired by a flow plug which is supplied with power at a high power level during cranking and at a lower power level during running.
