Definitions
- the invention is based on a diagnostic method according to the type of the main claim.
- the working behavior of the internal combustion engine is influenced by variations in the intake / exhaust valve control and / or by variations in the intake manifold or intake tract geometry.
- the intake / exhaust valve control takes place either between two actuator options, e.g. B. in the camshaft changeover, instead of or the intake / exhaust valve control takes place continuously such.
- the resonance charging of the combustion chambers in the respective operating state of the internal combustion engine is optimized by variations in the intake manifold or intake tract geometry, whereby an increased air supply into the combustion chambers of the internal combustion engine is made possible with the other unchanged position of other actuators, in particular the throttle valve.
- other actuators in particular the throttle valve.
- the variations occur either discontinuously, e.g. B. by actuating resonance flaps in the intake manifold or intake tract, or the variations take place continuously by controlling a number of actuating options of one or more actuators.
- EP-A 170 018 a method for self-diagnosis of an actuator of an idle charge control in internal combustion engines is known.
- an arbitrary actuator control for diagnosis is used for diagnosis of the actuator, i. H. that instead of the controls of the actuators to be diagnosed which optimize the other operational sequences, one or more defined actuator controls take place and their effects on other operating data of the internal combustion engine are analyzed.
- the diagnosis can therefore only take place during certain, in particular stationary, operating states, since otherwise the program-specific, ie. H. would be disturbed by further actuators optimized operation of the internal combustion engine in its process.
- the diagnostic method according to the invention enables diagnosis of the actuators for varying intake / exhaust valve control and / or for varying the intake manifold or intake tract geometry in the case of actuator controls which take place within the framework of the programmable controls of the internal combustion engine which optimize the operating sequence , without additional hardware effort, e.g. B. in the form of position indicators to require.
- the data already present during normal operation of the internal combustion engine can be used for diagnosis for the diagnostic method presented here. It is particularly advantageous that the area accessible to diagnosis is not limited to the control device of the actuating device and the actuator itself. Rather, the diagnosed Area extended by this method according to the invention to all elements of the chain of effects with the variable intake manifold or intake tract geometry and / or the intake / exhaust valve control.
- the diagnostic method for checking actuators for controlling an internal combustion engine is to be shown on the basis of a block diagram.
- the actuators to be diagnosed are those for variations in the intake manifold or intake tract geometry and / or for variations in the intake / exhaust valve control.
- position 1 denotes an internal combustion engine, to which the air required for combustion is supplied through an intake manifold 2 or an intake tract.
- Position 3 summarizes actuators for varying the intake manifold or intake tract geometry and position 4 controls for varying the intake / exhaust valve control.
- the actuators to be diagnosed are controlled by control units, which are summarized in position 5 for the sake of clarity.
- B the measured by an air flow meter or air mass meter 6 air volume or air mass QL supplied.
- the control of both the variations in the intake manifold or intake tract geometry 3 and the variations in the intake / exhaust valve control 4 cause the operating point of the internal combustion engine 1 to change. This changes a or Several operating data that can only be attributed indirectly to this actuator control of the actuators 3 and 4. So changes z. B. the amount of air or air mass QL sucked in through the suction pipe or the intake tract 2, which is measured by the air flow meter or air mass meter 6.
- the control device 5 controls depending on the operating parameters of the internal combustion engine 1, in particular the speed n and / or the load L, the actuators for varying the intake manifold or intake tract geometry 3 and / or the actuators for varying the intake / exhaust valve control 4. It can now two methods of diagnosis can be used:
- control signals of the actuators to be diagnosed which are within the scope of the program, ie. H. the controls that optimize the operating sequence of the internal combustion engine take place, fed to the diagnostic unit 7.
- the air volume or air mass QL measured by the air flow meter or air mass meter 6 is stored as actual values and compared with stored target values. Either individual actuator variations are compared with corresponding setpoints, or the entire actuator variations are compared with stored function profiles.
