Abstract
A fuel injector includes a first fuel path, a second fuel path, and an air path. The first fuel path is independent from the second fuel path. The ratio of a first outlet area of the first fuel path, a second outlet area of the second fuel path, and a third outlet area of the air path is constant. A fuel system includes a first fuel source, a second fuel source, an air source, and the injection. The first fuel source is fluidly connected to the first fuel path. The second fuel source is fluidly connected to the second fuel path. The air source is fluidly connected to the air path.
