Abstract:
A fuel injection system includes a fuel supply passage configured to receive a pressurized fuel, a nozzle orifice downstream of the fuel supply passage, and an injection valve positionable to open the nozzle orifice and to close the nozzle orifice. The injection valve has a first configuration with a first lift and a second configuration with a second lift, the first lift being different than the second lift. The fuel injection system includes a fluid-actuated lift control valve configured to cause the injection valve to change from the first configuration to the second configuration.
