Stand der TechnikState of the art
Für Kraftfahrzeuge ist ein schneller Wiederstart ihrer Verbrennungskraftmaschine nach deren Stopp, wie er für ISS (Instant Start System) und HEV (Hybrid Electric Vehicle) Anwendungen typisch ist, von hoher Bedeutung. Für direkteinspritzende, selbstzündende Verbrennungskraftmaschinen ist es dabei wichtig, in einem Common-Rail-System in möglichst kurzer Zeit so viel Raildruck bereitzustellen, dass eine Zündung eines Kraftstoff-Luftgemisches in einem Kolben mindestens auf den zweiten, besser aber auf den ersten auf einen Startwunsch folgenden oberen Totpunkt (OT) des Kolbens erfolgen kann. Verbrennungskraftmaschinen mit ZME-sauggedrosselten Hochdruckkraftstoffpumpen (ZME = Zumesseinheit) stellen einen schnellen Druckaufbau sicher, da die Hochdruckkraftstoffpumpe nach Drehbeginn bereits mit dem ersten möglichen Förderhub Kraftstoff fördert. For motor vehicles, a rapid restart of their internal combustion engine after the stop, as is typical for ISS (Instant Start System) and HEV (Hybrid Electric Vehicle) applications, is of great importance. For direct injection, self-igniting internal combustion engines, it is important to provide in a common rail system in the shortest possible time so much rail pressure that ignition of a fuel-air mixture in a piston at least on the second, but better on the first following a start request top dead center (TDC) of the piston can be done. Internal combustion engines with ZME suction-throttled high-pressure fuel pumps (ZME = metering unit) ensure rapid pressure build-up, since the high-pressure fuel pump delivers fuel already after the start of rotation with the first possible delivery stroke.
Dies kann beispielsweise dadurch erreicht werden, dass die Hochdruckkraftstoffpumpe befüllt abgestellt wird, mechanisch-hydraulische Rückschlagventile besitzt und deshalb für das Fördern von Kraftstoff nicht auf eine Synchronisation bzw. eine Erkennung der Position der Verbrennungskraftmaschine angewiesen ist.This can be achieved, for example, by the fact that the high-pressure fuel pump is turned off, has mechanical-hydraulic check valves and is therefore not dependent on a synchronization or detection of the position of the internal combustion engine for conveying fuel.
Die
Offenbarung der ErfindungDisclosure of the invention
Das erfindungsgemäße Verfahren zur Steuerung und Regelung einer mit einem Einlassventil mit elektromagnetischem Aktor versehenen Hochdruckkraftstoffpumpe einer Verbrennungskraftmaschine umfasst ein Bestromen des elektromagnetischen Aktors gemäß einer vorgegebenen Bestromungsstrategie, sodass während eines Förderzyklus eines Förderkolbens der Hochdruckkraftstoffpumpe der elektromagnetische Aktor die Förderleistung der Hochdruckkraftstoffpumpe nicht beeinflusst, wenn keine Erkennung der Position der Verbrennungskraftmaschine erfolgt ist, und ein Bestromen des elektromagnetischen Aktors in Abhängigkeit von der Position der Verbrennungskraftmaschine, nachdem eine Erkennung der Position der Verbrennungskraftmaschine erfolgt ist. Das erfindungsgemäße Verfahren stellt ab dem Start der Verbrennungskraftmaschine die Förderung von Kraftstoff ab dem ersten Förderhub der Hochdruckkraftstoffpumpe sicher. Sobald eine Erkennung der Position der Verbrennungskraftmaschine bzw. eine Synchronisation erfolgt ist, wird auf die für eine Hochdruckkraftstoffpumpe, welche über ein mit einem elektromagnetischen Aktor versehenes Einlassventil als Saugventil verfügt, übliche positionsabhängige Ansteuerung des elektromagnetischen Aktors umgeschaltet. The method according to the invention for controlling and regulating a high pressure fuel pump of an internal combustion engine provided with an inlet valve with electromagnetic actuator comprises energizing the electromagnetic actuator in accordance with a predetermined energization strategy such that during a delivery cycle of a delivery piston of the high pressure fuel pump the electromagnetic actuator does not affect the delivery of the high pressure fuel pump, if no detection the position of the internal combustion engine has been carried out, and an energizing of the electromagnetic actuator in dependence on the position of the internal combustion engine, after a detection of the position of the internal combustion engine is carried out. The inventive method ensures from the start of the internal combustion engine, the promotion of fuel from the first delivery stroke of the high-pressure fuel pump. As soon as a detection of the position of the internal combustion engine or a synchronization has taken place, the usual position-dependent control of the electromagnetic actuator is switched to that for a high-pressure fuel pump, which has a provided with an electromagnetic actuator inlet valve as a suction valve.
In einer Ausführungsform des erfindungsgemäßen Verfahrens ist bevorzugt, dass die vorgegebene Bestromungsstrategie eine Bestromung des elektromagnetischen Aktors in Intervallen vorsieht. Besonders bevorzugt erfolgt die Bestromung in Intervallen mit einer Frequenz die höher als die Förderfrequenz der Hochdruckkraftstoffpumpe ist. Während eine Dauerbestromung des elektromagnetischen Aktors zu einer dauerhaft auftretenden hohen Verlustleistung in einer Spule des Aktors und im Steuergerät der Hochdruckkraftstoffpumpe und der Verbrennungskraftmaschine führt, können durch Bestromungsimpulse ein Schließen des Einlassventils und ein frühzeitiger Förderhub der Hochdruckkraftstoffpumpe mit geringerer Verlustleistung erzielt werden. Wenn sich das Einlassventil der Hochdruckkraftstoffpumpe dabei schließt, so bleibt es aufgrund seines Aufbauprinzips geschlossen.In one embodiment of the method according to the invention, it is preferred that the predetermined energization strategy provides for energization of the electromagnetic actuator at intervals. Particularly preferably, the energization takes place at intervals with a frequency which is higher than the delivery frequency of the high-pressure fuel pump. While a continuous current of the electromagnetic actuator leads to a permanently occurring high power loss in a coil of the actuator and in the control unit of the high-pressure fuel pump and the internal combustion engine can be achieved by Bestromungsimpulse closing the intake valve and an early delivery stroke of the high-pressure fuel pump with less power loss. If the inlet valve of the high pressure fuel pump closes, it remains closed due to its construction principle.
In einer anderen Ausführungsform der Erfindung ist es bevorzugt, dass die vorgegebene Bestromungsstrategie eine Dauerbestromung des elektromagnetischen Aktors vorsieht. Dadurch wird ein Kolben des Einlassventils nicht mehr in eine geöffnete Position gedrückt. Das Einlassventil ist dann in der Lage, wie ein konventionelles Einlassventil mechanisch-hydraulisch zu öffnen und zu schließen. Die Hochdruckkraftstoffpumpe fördert dadurch im dauerbestromten Zustand bereits eine hohe Menge Kraftstoff, die sich aber nicht regeln lässt.In another embodiment of the invention, it is preferred that the predetermined energization strategy provides a continuous energization of the electromagnetic actuator. As a result, a piston of the intake valve is no longer pressed into an open position. The inlet valve is then able to mechanically-hydraulically open and close like a conventional inlet valve. The high-pressure fuel pump thereby promotes a high amount of fuel in the steady-state condition, which can not be regulated.
Das erfindungsgemäße Computerprogramm führt alle Schritte des erfindungsgemäßen Verfahrens aus, wenn es auf einem Rechengerät oder Steuergerät abläuft. Um eine Implementierung des erfindungsgemäßen Verfahrens in einem vorhandenen Steuergerät zu ermöglichen, ohne daran bauliche Veränderungen vornehmen zu müssen, ist das erfindungsgemäße Computerprogrammprodukt mit Programmcode vorgesehen, der auf einem maschinenlesbaren Träger gespeichert ist und zur Durchführung des erfindungsgemäßen Verfahrens dient, wenn das Programm auf einem Computer oder Steuergerät ausgeführt wird. Durch Aufspielen des erfindungsgemäßen Computerprogramms auf ein Steuergerät wird das erfindungsgemäße Steuergerät erhalten, das dazu ausgebildet ist, eine mit einem Einlassventil mit elektromagnetischem Aktor versehene Hochdruckkraftstoffpumpe einer Verbrennungskraftmaschine mittels des erfindungsgemäßen Verfahrens zu steuern und zu regeln.The computer program according to the invention performs all the steps of the method according to the invention when it runs on a computing device or control unit. In order to enable an implementation of the method according to the invention in an existing control unit without having to make structural changes, the computer program product according to the invention is provided with program code which is stored on a machine-readable carrier and serves for carrying out the method according to the invention when the program is on a computer or control unit is running.
