<p>Some engines employ a fuel for purposes other than for combusting in motoring. These engines take longer to start and have reduced efficiency in certain operating modes. An improved fuel system for an internal combustion engine comprises a fuel supply in fluid communication with and supplying a fuel for motoring the internal combustion engine. A fuel employer is in fluid communication with the fuel supply and employs the fuel for purposes other than as a source of energy for combusting in the internal combustion engine. There is a valve for selectively enabling fluid communication between the fuel supply and the fuel employer. The valve is closed to disable the fuel employer when not needed to reduce the demand on the fuel supply.</p> |
