Definitions
- the invention is based on a device for delivering fuel and a method for pressure detection according to the preamble of claims 1 and 4 respectively.
- a device is already known from DE 100 43 688 AI, with a feed pump, a pressure line leading from the feed pump to the internal combustion engine, a check valve arranged in the pressure line downstream of the feed pump and a pressure sensor connected to the pressure line downstream of the check valve.
- the pressure sensor is provided on a so-called fuel distributor and detects the pressure in the fuel distributor and in the pressure line.
- an additional pressure sensor in the storage container is necessary in order to be able to detect a leak in the storage container.
- the device according to the invention and the method according to the invention with the characterizing features of claims 1 and 3 has the advantage that simple and In this way, the manufacturing costs of the device can be reduced by the pressure sensor being operatively connected to the pressure line downstream of the feed pump and upstream of the check valve. In this way, both the pressure in the pressure line and in the storage container can be detected at different times with a single pressure sensor. The additional pressure sensor in the storage container can be saved.
- the pressure sensor has a temperature sensor r since the temperature of the fuel drawn from the storage container is additionally determined in this way.
- the pressure sensor is used for the pressure detection in the pressure line and for the pressure detection in the storage container.
- the measurement signal of the pressure sensor is used as a control variable for regulating the feed pump and / or for leak diagnosis in the pressure line and / or for a tank leak diagnosis.
- the pressure sensor can take over one or more of the aforementioned functions. No additional components are required.
- time pressure curve in the reservoir is measured in the tank leak diagnosis, since a tank leak in the reservoir can be detected in this way.
- the tank leak is diagnosed as a leak in the storage container closed if, after a predetermined diagnosis time, a pressure change is measured which is greater than a predetermined pressure change, an overpressure or underpressure being present in the storage container before the tank leak diagnosis begins.
- a leak in the storage container can advantageously also be inferred if, after a predetermined diagnosis time, a pressure change is measured which is smaller than a predetermined pressure change, with atmospheric pressure prevailing in the storage container before the tank leak diagnosis begins.
- a leak in the pressure line downstream of the check valve is concluded in the pressure line leak diagnosis when the measurement signal of the pressure sensor drops below a predetermined value.
- the drawing shows a device for conveying fuel according to the invention.
- the device according to the invention has a storage container 1 with, for example, a storage container 2 arranged therein, in which a feed pump 3 is arranged, which sucks the fuel stored in the storage container 1, for example via a prefilter 4 and an intake line 5, from the storage container 2 and increases the pressure via a pressure line 8 promotes, for example, to a fuel distributor 9 of an internal combustion engine 10.
- the fuel rail 9 is defined as part of the pressure line 8.
- the fuel distributor 9 is connected to a plurality of injection valves 11, which inject the fuel into an intake manifold or cylinder of the internal combustion engine 10 in a manner not shown.
- the pressure line 8 can, however, also be connected downstream to a high-pressure pump of a so-called gasoline direct injection or a diesel injection system, which injects the fuel under high pressure into the fuel distributor and, via injection valves, into cylinders of the internal combustion engine 10.
- a high-pressure pump of a so-called gasoline direct injection or a diesel injection system which injects the fuel under high pressure into the fuel distributor and, via injection valves, into cylinders of the internal combustion engine 10.
- the storage container 2 provided, for example, stores sufficient fuel to ensure that the internal combustion engine 10 is supplied with fuel by the feed pump 3, even if no fuel is conveyed into the storage container 2, for example due to cornering and the resulting sloshing movements of the fuel in the storage container 1.
- the storage tank 2 is filled in a known manner via a suction jet pump, not shown, which is fed by the feed pump 3 and which feeds fuel from the storage tank 1 into the storage tank 2.
- the storage container 2 is arranged with its pot bottom 12 near a container bottom 15 of the storage container 1.
- the feed pump 3 is, for example, a flow pump that is driven electrically by an actuator, for example an armature of an electric motor, but can also be any other pump.
- the pre-filter 4 protects the device downstream of the pre-filter 4 from coarse dirt particles contained in the fuel.
- a check valve 16, for example, is arranged in the pressure line 8 downstream of the feed pump 3, which prevents fuel from flowing back from downstream of the check valve 16 to the upstream of the check valve 16 and in this way the excess pressure built up in the pressure line 8 by the feed pump 3 in the pressure line 8 is maintained downstream of the check valve 16 even after the feed pump 3 has been switched off.
- a main filter 17 is provided downstream of the check valve 16, for example, which filters out the fine dirt particles contained in the fuel.
- a branch line 18 branches off from the pressure line 8 downstream of the main filter 17.
- the branch line 18 is connected to a pressure regulator 19, which opens at a pressure in the pressure line 8 which is greater than a predetermined opening pressure, and fuel from the pressure line 8 via the branch line 18, the opened pressure regulator 19 and a return line 22 into the storage tank 2 can run back. In this way, the pressure in the pressure line 8 is kept at a constant value.
- the device has a pressure sensor 23, which is operatively connected via a connecting line 24 to the pressure line 8 downstream of the feed pump 3 and upstream of the check valve 16, for example in a flow connection.
- the pressure sensor 23 measures, for example, a differential pressure to the atmosphere or an absolute pressure.
- a measurement signal of the pressure sensor 23 corresponding to the measured pressure is sent via a signal line 26 to an electronic engine control 29.
- the pressure sensor 23 is used for the pressure detection in the pressure line 8 and for the pressure detection in the storage container 1.
- the measurement signal of the pressure sensor 23 serves, for example, as a so-called control variable for regulating the feed pump 3, so that only the amount of fuel that is required in the respective operating state of the internal combustion engine 10 is delivered to the fuel distributor 9. Therefore, the feed pump 3 requires less electrical power than an uncontrolled feed pump 3 that runs at full power regardless of the operating state of the internal combustion engine 10. This leads to significant fuel savings.
- the branch line 18 with the pressure regulator 19 and the return line 22 can be omitted.
- the measurement signal of the pressure sensor 23 can also serve as a so-called control variable for controlling a high-pressure pump arranged in the pressure line 8 downstream of the check valve 16 with the same advantages mentioned above.
- the pressure sensor 23 can also be used for leak diagnosis in the pressure line 8, 9.
- a leak in the pressure line 8, 9 is concluded when the measurement signal of the pressure sensor 23 falls below a predetermined value when the feed pump 3 is switched on.
- the pressure sensor 23 is used according to the invention for a tank leak diagnosis.
- tank leak diagnoses work in such a way that the time course of an overpressure or underpressure present in the storage container 1 is measured.
- the overpressure or underpressure in the storage container 1 can be generated by means of a pump.
- the natural heating of the storage container 1 after switching off the internal combustion engine 10 of a vehicle can also be used in a known manner, which causes a slight increase in pressure in the storage container 1.
- the tank leak diagnosis is carried out, for example, after the internal combustion engine 10 has been switched off, when the storage container 1 is hermetically sealed from the environment.
- the feed pump 3 is switched off, the check valve 16 is closed and a tank ventilation line (not shown) leading from the storage container 1 to the internal combustion engine 10 is closed by closing a tank ventilation valve provided in the tank ventilation line.
- An activated carbon canister for example, is arranged in the tank ventilation line upstream of the tank ventilation valve and is connected to the atmosphere via a ventilation line, a further valve being provided in the ventilation line, which valve is also closed before the tank leak diagnosis is carried out.
- the pressure sensor 23 measures the pressure in the pressure line 8 downstream of the feed pump 3 and upstream of the check valve 16.
- the check valve 16 When the feed pump 3 is switched on, the check valve 16 is opened because of the fuel delivery in the direction of the internal combustion engine 10, so that the pressure in the pressure line 8 downstream of the feed pump 3 and upstream of the check valve 16 minus pressure losses of the check valve 16 and the pressure line 8, the pressure in the pressure line 8 downstream of the check valve 16 and the pressure in the fuel rail 9 corresponds.
- the pressure in the pressure line 8 downstream of the check valve 16 and the pressure in the fuel distributor 9 is referred to below as the system pressure. Because the system pressure is the desired one Is the controlled variable, the motor controller 29 corrects the measurement signal of the pressure sensor 23 by the pressure loss of, for example, the check valve 16, the main filter 17 and / or the pressure line 8, 9.
- the check valve 16 When the feed pump 3 is switched off, the check valve 16 is closed and the excess pressure built up by the feed pump 3 in the pressure line 8 upstream of the check valve 16 has dropped to a lower pressure which, since the pressure line 8 upstream of the check valve 16 via the feed pump 3, the suction line 5 and the prefilter 4 is in flow communication with the storage container 2, composed of a pressure component, hereinafter referred to as gas pressure, of a gas formed from fuel vapors and air above a liquid level 25 in the storage container 1 and storage container 2 and a hydrostatic pressure component, which is dependent on a fill level in the storage container 1 and in the storage container 2 and by the pressure of a so-called liquid column above the branch line 24 is formed.
- gas pressure a pressure component
- hydrostatic pressure component which is dependent on a fill level in the storage container 1 and in the storage container 2 and by the pressure of a so-called liquid column above the branch line 24 is formed.
- the pressure sensor 23 Since the time course of the gas pressure is considered for the tank leak diagnosis, it is irrelevant that the pressure sensor 23 does not measure the gas pressure when the feed pump 3 is switched off, but rather a pressure which is composed of the gas pressure and a hydrostatic pressure component which is dependent on the fill level. It is not necessary to correct the measurement signal of the pressure sensor 23 by the hydrostatic pressure component, since the fill level in the storage container 1 and in the storage container 2 remains constant during the tank leak diagnosis and only the pressure change in the storage container 1 is monitored.
- the tank leak diagnosis can be started according to any criterion become.
- the engine control 29 monitors the time course of the measurement signal of the pressure sensor 23. If the overpressure or underpressure in the reservoir 1 is already present before the start of the tank leak diagnosis, for example generated by a pump or by natural, temperature-related pressure build-up, a leak is concluded if after a predetermined one Diagnosis time a pressure change is determined that is greater than a predetermined pressure change. This conclusion arises from the fact that the overpressure or underpressure in the storage container 1 is reduced by a leak, as a result of which a pressure change occurs which is greater than the predetermined pressure change.
- a leak is concluded if after a predetermined diagnosis time a pressure change is determined which is smaller than a predetermined pressure change. This conclusion arises from the fact that, in the presence of a leak in the storage container 1, no or only a slight overpressure can occur in the storage container 1.
