Abstract
A system is described that extends the driving range provided in prior art by compressed gas fuel systems and that thereby reduces the need for bi-fuel operating capability in most applications. The system can typically more than double the energy density of a compressed gas fuel storage system. The system includes apparatus for metering the fuel supplied to the engine to minimize noxious emissions.
Claims13
A dual fuel storage system, which comprises at least two fuels in a common pressurized container, wherein at least one of said fuels has a critical temperature below 20.degree. centigrade hereafter referred to as a low critical temperature fuel (LCT), and wherein at least one of said fuels in said duel fuel system has a critical temperature at or above 20.degree. centigrade hereafter referred to as high critical temperature fuel (HCT) such that a portion of said LCT fuel is dissolved in the second of said fuels.
