Abstract
A fuel injector includes a nozzle including at least one outer orifice. The at least one outer orifice selectively injects a first fuel. An outer check is disposed movably within the nozzle. The outer check includes at least one first orifice and at least one second orifice. The at least one first orifice and the at least one second orifice are disposed circumferentially spaced apart with respect to one another. Each of the at least one first orifice and the at least one second orifice selectively injects a second fuel. An inner check is disposed movably and concentrically within the outer check. The at least one outer orifice is adapted to selectively injects at least one of the first fuel and the second fuel therethrough based on a position of each of the outer check and the inner check.
