Figure 1 shows the combustion envelope of hydrogen compared to the combustion envelope of gasoline and illustrates a goal achieved by the invention in maintaining an optimum and uniform combustion rate for hydrogen throughout the effective range of engine RPM. As used herein, the "combustion envelope" refers to the
-
With reference to Figure 1, it is an object of the invention to regulate a hydrogen fuel gas mixture that is introduced into the engine combustion chamber such that the burn rate of the hydrogen fuel gaS remains constant regardless of engine RPM. …
-
The combustion characteristics and high volatility of hydrogen can be charted with reference to an axis correlated to the running speed of an internal combustion engine, as illustrated by the narrow combustion envelope for hydrogen, shown in Figure 1 at 1 in contrast with the combustion envelope, for example, in gasoline, 2.
-
… Nevertheless, because of the wide combustion window for gasoline, optimum tuning at 60 MPH as shown at 2 in Figure 1 will allow satisfactory engine operation to other speeds. In the prior art, use of unmodulated hydrogen allowed engine operation only in the narrow envelope figuratively shown in curve l.

amplitude, pulse frequency and gated pulse frequency associated with operation of the fuel cell 7. (See U.S. Letters Patent 4,936,961, Figure 1, and U.S. Letters Patent 4,798,661.) and is operatively interconnected to the gas management module.
-
… The System of the invention modulates the hydrogen component of the overall gas mixture such that the burn rate of the hydrogen-containing fuel mixture approximates that of a fossil fuel as illustrated in Figure 1.
