Nissan Armada Fuel Rail

The Fuel Rail is a pressurized pipeline responsible for delivering fuel from the pump to the injector on each cylinder of the Nissan Armada. This ensures that the engine performs strongly and with clean emissions. In earlier models, the Fuel Rail worked with port fuel injectors located in the intake manifold runners. A regulator kept pressure constant in these systems, while the PCM shortened or lengthened injector pulse width to match load. Subsequent iterations of the gasoline direct injection engines employed common rail architecture, which has much higher pressure, so the Fuel Rail feeds quick response solenoid injectors, misting finer droplets that burn more completely. The primary evolution is the shift from low pressure port systems to high pressure common systems, where the new Fuel Rail will withstand greater than 2,000 bar to enhance performance, reduce consumption, and control emissions. Both designs sit tucked under the intake so that owners of the Armada won't notice the change; it is rare, however. Each Nissan retains unique rail shapes and mounting points. A uniform supply of pressure, regardless of the driving conditions, keeps the Nissan Armada engine smooth, whether on a daily drive or towing. The Fuel Rail is essential for optimal engine performance.
