Abstract
A system is provided for generating an alarm when the fuel surface level of an engine driven generator becomes smaller than a predetermined value, and stopping the engine after a predetermined time lapse from generating the alarm. Fuel shortage is detected by a fuel caution unit to cause an alarm unit to operate and further cause an engine stop unit to operate. The fuel caution unit causes the engine stop unit to stop after a short time lapse if the engine is restarted after the detection of fuel shortage. The system further includes an oil caution unit, overload caution unit, battery caution unit and power monitor accessories unit.
Claims7
A fuel shortage detection system for an engine driven generator comprising:
- means for detecting a fuel shortage condition depending on measuring of the level of fuel in a fuel tank and for producing a level signal;
- alarm means responsive to said signal from said detection means for generating an alarm;
- timer means for providing time lapse signal when said signal from said detection means lasts for a predetermined time;
- restart detection means for detecting that said engine is caused to restart and for providing a restart signal;
- output means responsive to said signal from said restart means for outputting a signal after a time lapse shorter than said predetermined time lapse;
- and
- engine stop means responsive to said signal from said timer means and said output means for stopping said engine.
