Abstract
Several embodiments of gaseous fuel supplying systems for an internal combustion engine used to power a portable generator. In each embodiment, heat is supplied to the fuel so as to maintain the fuel pressure if the fuel pressure falls below a predetermined pressure. In some embodiments, the heat supply is on-off and in other embodiments it is variable. In certain embodiments, the heat is supplied electrically and in another embodiment, the heat is extracted from the engine. In addition, one embodiment incorporates a cold starting arrangement wherein fuel is supplied to the engine for cold starting at full container pressure.
