Patent ID: 6923168

Claim:
A power generating system, comprising: an internal combustion engine; a starter/generator operatively coupled to the engine, the starter/generator adapted to start the engine from a standstill condition and bring the engine to an operational speed sustainable by the engine alone whereupon said starter/generator supplies back-up electrical power to a load; a plurality of redundant fuel tanks each containing fuel at a respective initial pressure level; and a fuel delivery system operatively coupling a selected one of said plurality of fuel tanks to said engine to supply said fuel thereto, said fuel delivery system supplying said fuel to said engine at a first reduced pressure level relative to the initial pressure level of said selected one of said plurality of fuel tanks while said starter/generator is starting said engine from said standstill condition, and supplying said fuel to said engine at a second reduced pressure level lower than said first reduced pressure level when said engine reaches said operational speed; wherein, supply of said fuel to said engine at said first reduced pressure level promotes fast start of said engine from said standstill condition.
