Definitions
- the invention initially relates to a fuel pump device for a fuel system one Internal combustion engine, especially with direct injection, with a fuel pump and one connected to it Drive motor.
- Such a fuel pump device from EP 0 725 212 A2 known.
- a fuel system is described in which a first fuel pump device fuel from a fuel tank to a second fuel pumping device and from there on over one High pressure area promotes to injectors.
- Both Fuel pump devices each include one Fuel pump and one with the fuel pump connected electric drive motor. The capacity Both fuel pumping devices can use the speed of the electric drive motor changed and adjusted become.
- the disadvantage of the known fuel pump device is of that their handling and integration into that Fuel system is difficult and therefore building the Makes the fuel system expensive. Also corresponds to the Pump performance not in all operating points of the Internal combustion engine the requirements.
- This task is carried out in a fuel pump device at the outset that the Fuel pump is a radial piston pump and the Drive motor and the fuel pump with one unit form a common fluid-tight housing.
- the design of the fuel pump as a radial piston pump enables the generation of high pressures, as in modern Fuel systems for internal combustion engines with gasoline direct injection required are.
- the fact that the Drive motor and fuel pump form one unit becomes the handling when building the fuel system considerably relieved. So the drive motor and Fuel pump existing unit are preassembled, so that when building the fuel system, for example in a motor vehicle only one common and not two separate parts must be handled.
- the housing of the drive motor and the Fuel pump in a common fluid-tight housing again improves the manageability of such designed fuel pumping device.
- There is one such a fluid-tight housing for the Fuel pump required so this is not or hardly leads to additional costs.
- the drive motor in the fluid-tight housing is housed ensures that the drive motor from contamination is protected from the outside. So less can pollution-tolerant but powerful Electric motors are used, which is again the Performance of the fuel pumping device benefits comes. Also the lifespan of the fuel pump device is improved by this measure.
- the efficiency of the fuel pump device according to the invention is also improved by the fact that otherwise required shaft seal from the Fuel pump to the drive motor can be omitted.
- a such shaft sealing is always with a certain Friction and some leakage, both of which reduces the efficiency of the fuel pump.
- the Eliminating the shaft seal also reduces costs.
- Fuel pumping device are in subclaims specified.
- the Fuel pump a drive shaft with at least one Bearing includes which is a rotor shaft of the Drive motor is.
- the drive motor is dispensed with.
- Fuel pump device is the Interior of the housing of the fuel pump and the Drive motor unit formed by fuel at least flows in the area of the drive motor. This has the Advantage that the drive motor by the fuel is cooled, which improves its efficiency.
- the flow guidance in the interior of the housing from the fuel pump and the drive motor unit is designed so that the fuel will at least drive the engine flowed through in areas and then to the fuel pump arrives, and that in the flow path between the drive motor and fuel pump a filter device, in particular a sieve, is present.
- Fuel pumping device is the high efficiency available throughout the life of the facility.
- the advanced training in which is also particularly compact the fuel pump drive shaft Has eccentric section and one around the eccentric section arranged around the ring and for each piston one with the Piston-connected slide shoe that bears against the cam ring are present, being in the radially outer peripheral surface of the cam ring a circumferential groove and in the shoe and in Pistons a radially extending channel are present.
- the Groove and the channels can be simple and inexpensive Way. Through the groove and the Channels can use less fuel Flow resistance can be performed. The bringing in complex bores, for example in a cylinder head the radial piston pump is therefore not required. This will additionally the costs are kept low.
- the fuel pumping device is aimed in the same direction, where the fuel pump is on Piston arranged suction valve comprises. This measure too reduces the dimensions of the fuel pumping device and the cost of making them.
- Valve element of the suction valve made of a ceramic Material is made.
- Such a ceramic Valve element builds relatively light, which advantages in terms on the valve dynamics.
- one is Valve element insensitive to wear, so that the service life of the fuel pump device designed in this way is high.
- Fuel pump device comprises this an electronic control unit, which drives the engine controls, with a control unit housing, which on the Housing of the fuel pump and the drive motor formed unit with at least one fastener is attached.
- An electronic control is for the most types of drive motors are required anyway the signals required for the drive in the to provide the desired way.
- the electronics are housed in a separate control section it can be optimally pre-assembled. In particular such pre-assembly conditions are adhered to, which for the error-free Operation of the control electronics are required.
- the control unit housing of the control unit on Housing of the fuel pump and the drive motor formed unit are attached. This still happens before they are installed on the internal combustion engine, the Assembly work on the internal combustion engine simplified.
- the fastener the wall of the housing of the fuel pump and the Drive motor formed unit penetrates, and that that Fasteners to the housing from the Fuel pump and the drive motor unit formed is sealed by a sealant.
- a sealant By that Fasteners the wall of the housing from the Fuel pump and the drive motor unit formed penetrates, becomes a particularly safe and stable Attachment of the control unit housing allows.
- the Sealant provided according to the invention is simultaneously ensures that fuel is in the housing is present, from this not to the control section can leak.
- a degassing duct leads to the outside. This ensures that if Fuel gases that pass or through the sealant this through from the interior of the housing of the Drive motor and the fuel pump to the outside, kept away from the sensitive control electronics and instead be derived into the environment.
- the assembly of the fuel pumping device is repeated simplified by the fact that the housing from the Fuel pump and the drive motor unit formed comprises at least two parts which are fluid-tight are connected to one another, the part of which Fuel pump and one connected to the drive shaft Rotor and part of the stator. Both parts can therefore independently of one another in different production sites can be pre-assembled. The Final assembly is still very easy.
- the invention also relates to a fuel system for a Internal combustion engine with direct injection, with a first Fuel pump, which fuel to a fuel pumping device that promotes a second fuel pump and an electric drive motor connected to it includes, and with a high pressure area in which the second Fuel pump promotes and at least one Fuel injector is connected.
