Abstract
A fuel injector () for alternate fuels (A,B) with different energy densities. Vanes (B) extend radially from a fuel delivery tube structure (B) with first and second fuel supply channels (A,B). Each vane has first and second radial passages (A,B) communicating with the respective fuel supply channels, and first and second sets of apertures (A,B). The first fuel supply channel, first radial passage, and first apertures form a first fuel delivery pathway providing a first fuel flow rate at a given fuel delivery pathway backpressure that is essentially common to both sets of fuel delivery pathway apertures. The second fuel supply channel, second radial passage, and second apertures form a second fuel delivery pathway providing a second fuel flow rate that may be at least 1 about twice the first fuel flow rate at the given fuel delivery pathway backpressure.
