Abstract:
A fuel delivery system for a direct injection internal combustion engine having two fuel rails and a plurality of fuel injectors attached to and fluidly connected with each fuel rail. A first fuel pump has its output connected with the first fuel rail while a second fuel pump has its output connected with the second fuel rail. A crossover pipe fluidly connects the outlets of both the first and second pumps. Both the first pump and the second pump each have an intake stroke and a pumping stroke. Furthermore, the intake stroke of the first pump coincides with the pumping stroke of the second pump and vice versa.
