Description
本発明は内燃機関の作動方法、殊に内燃機関の噴射弁を駆動制御する方法に関する。本発明はさらに内燃機関の作動の制御装置並びにこの種の制御装置のためのコンピュータプログラムに関する。 The present invention relates to a method for operating an internal combustion engine, and more particularly to a method for driving and controlling an injection valve of an internal combustion engine. The invention further relates to a control device for the operation of the internal combustion engine and to a computer program for such a control device.
従来技術では、例えばドイツ連邦共和国特許第10011690号明細書またはドイツ連邦共和国出願公開第10012025号公報から、内燃機関の噴射弁の量誤差を補償する方法が基本的に公知である。これらの文献から公知の方法は殊に、内燃機関の層状モード(λ>1)時の燃料高圧噴射弁での量許容差の適合に関する。これらの方法は普遍的である。すなわち異なる構造様式および作用を有する燃料噴射弁に適用可能である。
In the prior art, for example, from
最適化されたスプレーガイドを伴う将来的な内燃機関を考慮して、燃料高圧噴射弁が開発されている。ここでは流量ないし内燃機関の燃焼室内に噴射されるべき燃料量が、噴射弁iの噴射時間tiおよび/またはニードルストロークNHを介して制御される。所望のニードルストロークNHはこのような高圧噴射弁において所望の噴射時間tiに対して、相応する必要な電気量が加えられることによって設定調整される。所望の駆動制御に必要な電気量は個々のケースにおいて、噴射弁を駆動制御する制御装置内に格納されている基準特性曲線に基づいて計算される。このような基準特性曲線では、流量Dは加えられるべき電気量(Ladung)Qを横軸にしてあらわされる。 In view of future internal combustion engines with optimized spray guides, high pressure fuel injectors have been developed. Here, the flow rate or the amount of fuel to be injected into the combustion chamber of the internal combustion engine is controlled via the injection time ti of the injection valve i and / or the needle stroke NH. The desired needle stroke NH is set and adjusted in such a high-pressure injection valve by adding the corresponding required quantity of electricity to the desired injection time ti. The quantity of electricity required for the desired drive control is calculated in each case on the basis of a reference characteristic curve stored in a control device for controlling the injection valve. In such a reference characteristic curve, the flow rate D is represented by the electric quantity (Ladung) Q to be added on the horizontal axis.
このようなD(Q)基準特性曲線NHRefは、図2に示されている。格納されているこの基準特性曲線は、選択された基準弁の特性または製造された同じタイプの多数の高圧噴射弁の平均特性をあらわす。従ってこの基準特性曲線は、製造および使用される同じタイプの個々の噴射弁の特性とは異なる。このような異なる特性曲線は図2において参照符号NH1またはNH2であらわされている。高圧噴射弁での量公差を適合する、冒頭で挙げた文献に記載された方法では、高圧噴射弁の平均的特性と個々の特性との間の上述した相違は考慮されない。この相違は同じように燃料調量時の不正確さの原因になり得る。
本発明の課題は、内燃機関での高圧噴射弁による燃料調量時に高い精度を実現する、内燃機関の作動方法、制御装置およびコンピュータプログラムを提供することである。 An object of the present invention is to provide an operation method, a control device, and a computer program of an internal combustion engine that realize high accuracy when fuel is metered by a high-pressure injection valve in the internal combustion engine.
上述の課題は、作動中に、使用されている噴射弁の個々の特性をあらわす流量−電気量特性曲線に応じて内燃機関の少なくとも1つの噴射弁を駆動制御することを特徴とする、内燃機関の作動方法、およびこの方法によって補正された勾配(ki)を有する個々のDi(Qi)特性曲線に基づいて内燃機関を制御することを特徴とする制御装置、および殊にこの制御装置に割り当てられた計算装置、例えばマイクロプロセッサ上で作動され、上述の方法を実行するのに適したプログラムコードを有していることを特徴とするコンピュータプログラムによって解決される。 An object of the invention is to provide an internal combustion engine characterized in that, during operation, at least one injection valve of the internal combustion engine is driven and controlled in accordance with a flow-electricity characteristic curve representing the individual characteristics of the used injection valve. And a control device for controlling an internal combustion engine on the basis of individual D i (Q i ) characteristic curves having a gradient (k i ) corrected by this method, and in particular this control device The invention is solved by a computer program running on a computing device, for example a microprocessor, assigned to the computer program and having program code suitable for performing the method described above.
このような個々の特性曲線を考慮することによって、同じタイプの噴射弁の平均的な特性のみをあらわす特性曲線が使用されていた従来技術と比較して、燃料調量時の精度が格段に改善される。向上されたこのような調量精度によって、将来的に計画されている、内燃機関の作動に対するスプレーガイド式燃焼方法の使用も可能になる。この燃焼方法は、従来方法と比べて排気ガスエミッションがより少なく、消費がより少ない点において傑出している。本発明による制御装置およびコンピュータプログラムの利点は、本発明の方法に関連して上述した利点に相応する。 By taking into account such individual characteristic curves, the accuracy at the time of fuel metering is remarkably improved compared to the conventional technology in which a characteristic curve representing only the average characteristic of the same type of injection valve was used. Is done. Such improved metering accuracy also allows the use of a spray-guided combustion method for the operation of internal combustion engines, which is planned in the future. This combustion method is distinguished by lower exhaust gas emissions and lower consumption compared to conventional methods. The advantages of the control device and the computer program according to the invention correspond to the advantages described above in connection with the method of the invention.
本発明による方法の有利な構成は従属請求項に記載されている。 Advantageous configurations of the method according to the invention are described in the dependent claims.
本発明を以下で種々の実施例の形において図を参照にして詳細に説明する。 BRIEF DESCRIPTION OF THE DRAWINGS The invention is explained in more detail below in the form of various embodiments with reference to the drawings.
詳細には、図1には内燃機関の個々の使用されている高圧噴射弁に対する流量−電気量特性曲線の勾配を計算する方法が示されている。ここで勾配kiは、流量と、所望のニードルストロークNHないし流量を得るために噴射弁に加えられるべき電気量との割合を示している。このような勾配を求めるために、内燃機関はまずいわゆる均質モード、すなわち例えばλ=1で作動される(ステップa))。 In particular, FIG. 1 shows a method for calculating the slope of the flow-electrical characteristic curve for the individual high-pressure injection valves of an internal combustion engine. Here gradient k i represents the flow rate, the ratio of the amount of electricity to be added to the injection valve in order to obtain the desired needle stroke NH or flow rate. To determine such a gradient, the internal combustion engine is first operated in a so-called homogeneous mode, ie, for example, λ = 1 (step a)).
その後、後続のステップb)において、いわゆる適合領域(Adaptionsbereich)が定められる。この適合領域内では基準作動点が適切に選択される。このような適合領域が定められない限り、本発明の方法は先へ進まず、その代わりにステップa)へ繰り返し戻る。 Then, in a subsequent step b), a so-called adaptation area (Adaptionsbereich) is defined. A reference operating point is appropriately selected within this adaptation region. Unless such a matching area is defined, the method of the invention does not proceed, but instead returns to step a) repeatedly.
適合領域に首尾良く達した後、このような適合領域内で基準作動点が設定調整される。この基準作動点は殊に、内燃機関の回転数並びに内燃機関に供給された各相対的なエアマスが静的(quasistationaer)であるという特徴を有している。さらに例えばλ=1およびこの基準作動点に属する噴射時間tiRefおよび噴射弁に加えられるべき属する電気量QRefが駆動制御される(ステップc))。 After successfully reaching the adaptation region, the reference operating point is set and adjusted in such an adaptation region. This reference operating point is characterized in particular by the fact that the rotational speed of the internal combustion engine and the respective relative air masses supplied to the internal combustion engine are quasistationers. Further, for example, λ = 1 and the injection time ti Ref belonging to this reference operating point and the belonging electric quantity Q Ref to be added to the injection valve are drive-controlled (step c)).
このような基準作動点が設定調整されるとすぐに、内燃機関で単独シリンダ−ラムダ測定がアクティブであるか否かが検査される(ステップd))。アクティブでない限り、本発明による方法は待機ループに移行する。これはステップc)に戻ることによって実現される。しかし単独シリンダ−ラムダ測定がアクティブである場合、噴射弁に加えられるべき電気量が、基準作動点の設定調整のために加えられるべき電気量QRefに対して、予め設定された値ΔQだけ調整される。このように電気量をΔQだけ調整することによって、まず値Δλだけラムダが変化する。この場合に基準作動点は実質的に変化しない。なぜなら均質モードでモーメント形成は、燃焼ラムダによってわずかにしか影響されないからである。 As soon as such a reference operating point has been set, it is checked whether the single cylinder-lambda measurement is active in the internal combustion engine (step d). As long as it is not active, the method according to the invention goes into a waiting loop. This is achieved by returning to step c). However, if single cylinder-lambda measurement is active, the quantity of electricity to be applied to the injector is adjusted by a preset value ΔQ with respect to the quantity of electricity Q Ref to be applied for the setting adjustment of the reference operating point. Is done. By adjusting the quantity of electricity by ΔQ in this manner, first, the lambda changes by the value Δλ. In this case, the reference operating point does not substantially change. This is because in homogeneous mode the moment formation is only slightly affected by the combustion lambda.
ここに記載された前提条件の下で、すなわち相対的なエアマスrlも噴射持続時間tiもそれぞれ静的なままであるという前提条件の下で、識別されたこのようなラムダ変化分は、噴射弁を流れる燃料量の特定の変化分ΔDに相当する。2つの量ΔλおよびΔQないしΔDおよびΔQから、使用されている噴射弁iの個々の勾配が以下の式に従って計算される:
ki=Δλ:ΔQ=ΔD:ΔQ (1)
このような個々の勾配kiによって、修正ファクタfkoorが計算される。この修正ファクタは、同じタイプの製造された多数の噴射弁の平均特性をあらわす所定の基準特性曲線の勾配に対する個々の勾配kiの偏差である。修正ファクタfkoorの計算は、以下の式に従って計算される:
fkoor=ki:kRef (2)
電気量の調整によって結果として生じた量λの変化を識別すること、および、修正ファクタの計算は、図1のステップf)において行われる。修正ファクタの計算が首尾良く行われない場合、本発明による方法はステップd)のスタートに戻るようにされている。
Under the prerequisites described here, that is, under the premise that both the relative air mass rl and the injection duration ti each remain static, such an identified lambda change is defined by the injection valve Corresponds to a specific change ΔD in the amount of fuel flowing through the fuel cell. From the two quantities Δλ and ΔQ or ΔD and ΔQ, the individual gradient of the injector i used is calculated according to the following formula:
k i = Δλ: ΔQ = ΔD: ΔQ (1)
With such individual gradients k i , a correction factor f koor is calculated. This correction factor is the deviation of the individual slopes k i from the slope of the predetermined reference characteristic curve which represents the average characteristic of a number of manufactured injection valves of the same type. The calculation of the correction factor f koor is calculated according to the following formula:
f koor = k i: k Ref (2)
The identification of the change of the quantity λ resulting from the adjustment of the quantity of electricity and the calculation of the correction factor are performed in step f) of FIG. If the calculation of the correction factor is not successful, the method according to the invention is adapted to return to the start of step d).
しかしこれに対して、修正ファクタの計算が首尾良く実行されると、これは、ステップg)において、使用噴射弁iに対して個々のDi/Qi特性曲線を計算するのに用いられる。既に上述したように、本発明に相応して計算された修正ファクタfkoorは、D(Q)特性曲線の勾配を噴射弁の実際の特性に整合させるためにのみ用いられる。生じ得るオフセット誤差は、本発明の方法では考慮されない。 However, on the other hand, if the calculation of the correction factor has been carried out successfully, it is used in step g) to calculate the individual D i / Q i characteristic curves for the used injector i. As already mentioned above, the correction factor f koor calculated according to the invention is only used to match the slope of the D (Q) characteristic curve to the actual characteristic of the injector. Possible offset errors are not taken into account in the method of the invention.
内燃機関の後の作動時に、本発明と相応に計算されて整合されたDi(Qi)特性曲線は、図1においてステップg)からステップa)への帰還によってあらわされているように、有利には、場合によっては生じ得るオフセット誤差が、基準特性曲線に対する使用されている噴射弁の特性曲線の勾配における本発明によって補償された誤差と比較して、無視できる場合、または同じように適切な方法によって補正される場合にのみ使用される。 During subsequent operation of the internal combustion engine, the D i (Q i ) characteristic curve calculated and matched correspondingly with the present invention, as represented by the return from step g) to step a) in FIG. Advantageously, if possible offset errors are negligible, or equally appropriate, as compared with the errors compensated by the invention in the slope of the characteristic curve of the injector used with respect to the reference characteristic curve. It is used only when it is corrected by an appropriate method.
図3には、上述の方法に従って内燃機関の噴射弁を駆動制御する制御装置100が示されている。
FIG. 3 shows a
