Series 4000Common Rail Fuel System • Two Fuel Pumps In Series • Electronic Pilot Injection • Engine Mounted Fuel Filters Between Fuel Pumps • Full Electronic Controlof Individual Cylinders • Complete Injection Timing Control • Beginning of Injection • Injection Duration • No Injector Cam Limitations Low PressureSensor Rail Pressure Regulator Control Connector High PressureSensor

  4. Series 4000Common Rail Fuel System Rail Pressure Sensor Pressure Limiting Valve Common Rail Flow Limiter Fuel Tank Injectors Filter ECM Controlled High Pressure Pump with Pre-Supply Pump Sensors

  5. Series 4000Common Rail Benefits • Reduced Emissions • Reduced Fuel Consumption • Reduced Noise Levels • Fewer Moving Parts • No Mechanical Adjustments Required

  6. Series 4000Fuel Injection SERIES 4000 CYLINDER PRESSURE • STANDARD INJECTION • Long ignition delays result in large quantities of • fuel being injected before beginning of combustion • It results in high rate of pressure rise, leading to • shorter life and increased noise 1450 1350 Normal Injection • ELECTRONIC PILOT INJECTION (EPI) • Small quantity of fuel is injected in advance of normal • injection • It reduces the rate of pressure rise, thereby improving life • and reducing noise & vibrations Optimized Injection 750 650 550 s) 450 2 4 6 8 350 250 0 -8 -6 -4 -2 10 12 14 16 18 20 22 24 26 28 30 -20 -18 -14 -12 -10 -16
