Definitions
- the present invention relates to a method for operating injectors of an injection system (rail) having an injection engine of an internal combustion engine, in particular a diesel engine, in which the needle movement of the injectors is controlled directly by an actuator.
- Injectors of internal combustion engines have manufacturing tolerances after their production. This has the consequence that each injector emits a different amount of fuel when driven with the same signal. It goes without saying that one tries to keep these deviations as small as possible.
- injectors discussed here are those in which the movement of the needle of the injector by an actuator directly, ie without servo valve, in particular via direct contact, via levers or via a hydraulic coupling, is controlled.
- Such directly controlled injectors have no switching leakage.
- Type 1 Deviation in opening and closing times
- Type 2 Deviation in the maximum rate Deviations, which consist of a combination of the two types mentioned above, are also possible.
- Various methods or strategies are known for reducing or eliminating such deviations.
- a classification of the corresponding injectors takes place.
- the injectors are measured at certain points and the corresponding deviations are coded. Subsequently, the coding on the
- Transfer control device of the internal combustion engine to use appropriate adoption functions can.
- Another method uses a closing time control to eliminate Type 1 deviations. In this case, the closing times of the injectors are detected and the deviations corrected.
- cylinder pressure indication for combustion history control and cylinder equalization is performed.
- cylinder balancing and quantity estimation occur based on a crankshaft acceleration signal.
- the present invention has for its object to provide a method of the kind described, with the deviations of the fuel levels to be metered by In ⁇ jectors determined and reduced / eliminated in a particularly simple and accurate manner.
- a method of the type specified which comprises the following steps: Determining the actual injection quantity of each injector of the injection system via the fuel quantity requested for each injector for a given time at the pump of the injection system or via the pressure loss in the pressure accumulator caused by the injection process;
- the above-mentioned object is achieved by a method of the type indicated, which comprises the following steps:
- Both embodiments of the method according to the invention take advantage of the fact that directly controlled injectors have no switching leakage.
- an injector since the removed during one cycle from the accumulator fuel amount of the A ⁇ injection quantity corresponding that has injected into the combustion chamber, an injector, a very accurate estimate of the inputs is injection volume possible, on the one hand over the loss of pressure in the pressure accumulator and secondly via the at the pump ge ⁇ demanded amount.
- the amount requested by the pump or the pressure loss in the pressure accumulator is therefore determined in the method according to the invention.
- the amount required at the pump is typically determined by its own controller also from the pressure curve in the pressure accumulator. This method works particularly well with a synchronously running piston pump, which can measure the fuel quantity individually for each cylinder.
- the ascertained requested fuel quantity or the determined pressure loss is compared with a desired fuel quantity or a desired pressure loss for each injector.
- This desired fuel quantity or this desired pressure loss are stored on the control device of the internal combustion engine.
- a control / control method for the reduction / elimination of the determined deviation is then performed.
- the determined requested fuel quantity or the determined pressure loss among the injectors of the injection system is adjusted.
- a corresponding control method for reducing / eliminating the detected deviation is performed.
- pressure control parameters are used to control and correct the injection quantities. The correlation between a volume-controlled pressure control and a leak-free injector actuation for fuel metering is exploited.
- an average or median value is formed from the determined requested fuel quantity or the pressure losses determined, and it will be intended all From ⁇ deviations of the values of the injectors from the mean or median value to perform the adjustment. A correction can then be made towards the mean or median value. In this and the previous method variant can also be determined whether a deviation is outside the correctable corridors.
- the correction of the deviation from ⁇ at the first and second embodiment of the method according to the invention via a suitable control / regulating ⁇ process is performed.
- a closing time control are performed as he STEU ⁇ / control method.
- Such a closing time control is known per se, wherein the opening and / or closing time of an injector is detected and compared with corresponding desired values. In this embodiment of the method according to the invention, such a closing time control with the determination of
- a correction is carried out via the adaptation of the activation duration of the injector.
- a correction is performed at a closing time ⁇ additionally to control a correction by adjusting the actuator energized.
- Such variants of the method can be, for example, Runaway ⁇ leads, when a deviation of type 1 (deviation in the opening and closing timings) is corrected out and the remaining process of the invention detected deviation can be uniquely assigned as a departure from type 2 (deviation in the maximum rate).
- a correction on the adjustment of the driving time of the injector takes place here, for example, a longer energization in the correction of the amount up or a shorter energization of the Actors in the correction of the amount down instead.
- an increase / reduction of energy or a modification of the drive profile can be performed.
- the method according to the invention has the particular advantage that it can be carried out as an on-board diagnosis during normal operation of the injection system. This allows automatic on-board detection of injector-to-injector deviations. This on-board implementation also includes the subsequent control procedure.
- a deviation (type 1) in the opening and / or closing timing of an injector via another method is Auskor ⁇ rigiert and the remaining deviation (type 2) is determined with the inventive method and a control / Control method reduced / eliminated.
- a deviation in the opening and / or closing time (type 1 described above) is determined and corrected.
- the deviation of the initially described type 2 (deviation in the maximum injection rate), which usually remains, is then determined using the method according to the invention
