Fuel Injectors

Fuel injectors, located in the intake manifold, spray atomized fuel directly toward associated intake valves. All injectors are supplied with fuel from a common fuel manifold. A signal from the fuel injection ECM controls injection pulse duration. On all models except 9000 Series Turbo, injectors open simultaneously once per engine revolution, except during cold starting. 9000 Series Turbo uses sequential port fuel injection. During cold starting, injectors open twice per revolution.
