Abstract
A fuel delivery system for a multi-fuel internal combustion engine and an approach for operating the fuel delivery system are provided. The fuel delivery system can be operated in two or more different fuel delivery modes according to operating conditions of the engine or fuel delivery system. A first example mode can be performed to concurrently deliver two or more fuels to the engine. A second example mode can be performed to transfer fuel from a first fuel storage tank to a second fuel storage tank. A third example mode can be performed to supply a fuel from a first fuel storage tank to at least two fuel injectors of each cylinder of the engine. In some embodiments, the various modes of operation may be selected by varying a fuel pressure that is provided by the fuel delivery system.
