Fuel Charging and Controls–3.2LDuratorq-TDCi(148kW/200PS) 303-04C-2 303-04C-2 - Puma DESCRIPTION AND OPERATION Fuel Charging and Controls Overview 1 6 4 5 3 E129822 Item Description 1 Fuel rail 2 Fuel injector(s) 3 Fuel pressure (FRP) sensor 4 Fuel metering valve 5 Fuel temperature sensor 6 Fuel pump General A common rail fuel injection system is used on the 3.2L Duratorq-TDCi (Puma) diesel engine. Within the fuel pump there is an integral fuel transfer pump which draws the fuel from the fuel tank to the fuel pump. A fuel metering valve is located in the supply port to the high-pressure chamber of the fuel pump. The fuel metering valve varies the quantity of fuel 2 supplied to the fuel rail and fuel injector(s), in relation to the driving conditions. The fuel is supplied at high-pressure to the fuel rail and to the fuel injectors ready for injection. Depending on engine operating conditions, the fuel injection pressure varies between 230 bar and 1600 bar. Fuel system pressure is measured using an FRP sensor located in the fuel rail. The FRP sensor converts the fuel system pressure into a voltage signal. This voltage signal acts as an input signal to the powertrain control module (PCM) for calculation of the fuel injection quantity. The power train control module (PCM) calculates the time of fuel injection and the fuel injection quantity depending on various input variables. The specified quantity of fuel is injected into the respective combustion chamber through the solenoid actuated fuel injector(s). In doing so, a pre-injection and a main injection occur each time. The excess fuel is returned to the fuel tank through the fuel return line.

The fuel pump has three pump elements, each offset from each other by 120 degrees. The fuel transfer pump is incorporated into the fuel pump and is located on the drive flange. The fuel transfer pump is a cycloid type pump. The fuel metering valve is actuated by the PCM using pulse width modulation. 4 5 6 7 8

The fuel rail is made from forged steel and is retained by a support bracket located on the camshaft carrier. The fuel is delivered by one high-pressure fuel supply line from the fuel pump to the fuel rail. From the fuel rail, the fuel travels through the high-pressure fuel supply line(s) to the fuel injector(s). Fuel injectors 1 6 2 3 5 4 E129444 Item Description 1 Fuel injector electrical connector 2 Fuel injector fuel return line clip 3 Fuel injector 4 Fuel injector sealing washer 5 Fuel injector nozzle 6 Fuel injector high-pressure fuel supply line union The fuel injector(s) are located centrally on the cylinder head upper section and are attached by means of retaining clamps. The fuel injector(s) are sealed from the combustion chamber by means of a copper sealing washer located between the fuel injector and the cylinder head. A new sealing washer must always be installed when carrying out installation work. The fuel injectors are controlled directly by the PCM. The fuel return line(s) are attached to the top of the fuel injector and are connected in series.

Highly flammable mixtures are always present and may ignite. Failure to follow these instructions may result in personal injury. Do not carry out any repairs to the fuel injection system with the engine running. The fuel pressure within the system can be as high as 1600 bar. Failure to follow this instruction may result in personal injury. Eye protection must be worn at all times when working on or near any fuel related components. Failure to follow this instruction may result in personal injury. CAUTIONS: Make sure that the workshop area in which the vehicle is being worked on is as clean and dust-free as possible. Areas in which work on clutches, brakes or where welding or machining are carried out are not suitable in view of the risk of contamination to the fuel system. Make sure that clean non-plated tools are used. Clean tools using a new brush that will not lose its bristles and fresh suitable evaporative cleaning agent, prior to starting work on the vehicle. Use a steel topped workbench and cover it with clean, lint-free non-flocking material. Make sure that all parts removed from the vehicle are placed on the lint-free non-flocking material. Make sure that any protective clothing worn is clean and made from lint-free non-flocking material. Make sure that any protective gloves worn are new and are of the non-powdered latex type. Before using the suitable evaporative cleaning agent, protect all electrical components and connectors with lint-free non-flocking material. 1. For additional information, refer to: Solvents, Sealants and Adhesives (100-00 General Information, Description and Operation) / Diesel Fuel System Health and Safety Precautions (100-00 General Information, Description and Operation). 2.
