The system consists of the following major components that are used to deliver low-pressure fuel to the unit injectors:Fuel tank - The fuel tank is used to store the fuel.Fuel priming pump - The fuel priming pump is used to evacuate the air from the fuel system. As the air is removed, the system fills with fuel.Fuel filters - The fuel/water separator is a 10 micron filter with a water separator. This filter is used to remove abrasive material and contamination from the fuel system that may be large enough to damage the fuel transfer pump. The secondary fuel filter, which is located on the secondary fuel filter base, is used to remove abrasive material and contamination. As small as 2 microns that could damage the injectors. The tertiary fuel filter is located on the secondary fuel filter base. The tertiary fuel filter is used to remove abrasive materials and contamination as small as 2 microns.Supply lines and return lines - Supply lines and return lines are used to deliver the fuel to the different components.The purpose of the low-pressure fuel supply circuit is to supply fuel that has been filtered to the fuel injectors at a rate and a pressure that is constant.Once the injectors receive the low-pressure fuel, the fuel is pressurized again before the fuel is injected into the cylinder. The unit injector uses mechanical energy that is provided by the camshaft to achieve pressures that can be in excess of 200000 kPa (30000 psi).Data from several of the engine systems is collected by the ECM and processed to manage these aspects of fuel injection control:
Injection timing
Fuel injection timing advance
Injection duration
Engine cold mode statusThe mechanical electronic fuel system relies on a large amount of data from the other engine systems. The data that is collected by the ECM will be used to provide optimum performance of the engine.Low-Pressure Fuel Supply Circuit
The flow of fuel through the system begins at fuel tank (7). Fuel that is drawn from the tank by the fuel transfer pump (11) is filtered through a fuel/water separator. The separator is a 10 micron filter with a water separator. Fuel flows from the filter to the fuel transfer pump. The fuel transfer pump incorporates a check valve (12). The fuel transfer pump will allow fuel to flow around the gears of the pump during priming of the fuel system. The fuel transfer pump also incorporates a pressure relief valve (14). The pressure relief valve is used to protect the fuel system from extreme pressure.The fuel transfer pump is engineered to produce an excess fuel flow throughout the fuel system. The excess fuel flow is used by the system to cool the fuel system components. The excess fuel flow also purges any air from the fuel system during operation. Air that can become trapped in the fuel system can cause cavitation that may damage the components of the unit injector.The fuel priming pump (10) is located on the fuel/water separators base. The fuel filter base and fuel/water separator (9) also incorporate a siphon break. The siphon break prevents fuel from draining from the fuel system when the engine is not in operation. The priming pump is an electric pump that directs the flow of fuel during the priming pump operation. The fuel flows through a secondary fuel filter base which contains the following filters: secondary and tertiary. The secondary filter (15) is a 2 micron fuel filter that is used to remove small abrasive particles that will cause premature wear to fuel system components. The tertiary filter (16) is a 2 micron filter that is used to remove small abrasive particles. The filtered fuel then flows out of the fuel filter and returns to the passages in the fuel filter base. The fuel pressure sensor and fuel temperature sensor is mounted in a manifold in the intake valley. Fuel pressure is measured both before and after the fuel flows through the filter. The fuel pressure is also measured after the filters and before fuel enters the fuel gallery. The signals that are generated by the sensors are used by the engine control to monitor the condition of the engine components. This information is also used to adjust the fuel delivery of the engine to optimize efficiency.The fuel is transferred by fuel supply lines (8) to the fuel gallery (1) in the cylinder head. Only a portion of the fuel that is supplied to the fuel injectors is used for engine operation. This unused fuel is discharged into the return passages of the fuel gallery. The fuel is returned to the fuel tank by the fuel return lines (4). A continuous flow of fuel is experienced within the low-pressure fuel system.During engine operation, fuel injectors (2) receive fuel from the low-pressure fuel system. The injector pressurizes the fuel to high pressure. The fuel is then injected into the cylinder. The excess fuel is returned to the tank. Refer to Systems Operation, "Unit Injector" for a complete explanation of the injection process.The fuel pressure regulators (3) are located in the fuel return. The pressure regulating valve allows the low-pressure fuel system to maintain a constant pressure. A flow control orifice is also located in the fuel return. The flow control orifice maintains a system back pressure that is constant. This back pressure improves priming capability of the fuel priming pump and prevents excessive heating of the fuel.Fuel cooler (5), if equipped, is typically located
