Description
Die Erfindung betrifft eine Kraftstoffversorgungsanlage, nämlich eine Common-Rail Kraftstoffversorgungsanlage, einer Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1. Des Weiteren betrifft die Erfindung ein Steuerventil einer Kraftstoffversorgungsanlage.The The invention relates to a fuel supply system, namely a Common-rail fuel supply system, an internal combustion engine according to the preamble of claim 1. Des Furthermore, the invention relates to a control valve of a fuel supply system.
Die
Die Einspritzcharakteristik eines Injektors in einen Zylinder der Brennkraftmaschine wird demnach durch das mit dem jeweiligen Injektor zusammenwirkende Schaltventil sowie Steuerventil bestimmt, wobei in das Schaltventil üblicherweise eine Zulaufdrossel und in das Steuerventil üblicherweise eine Ablaufdrossel integriert ist, durch die zur Einstellung eines Druckverhältnisses an einem Kolben des jeweiligen Schaltventils Kraftstoff fließen kann. Der Kraftstofffluss durch die Ablaufdrossel eines Steuerventils wird durch einen Ventilkörper des jeweiligen Steuerventils bestimmt, der mit einem Ventilsitz desselben zusammenwirkt.The Injection characteristic of an injector in a cylinder of the internal combustion engine is therefore by the cooperating with the respective injector Switching valve and control valve determines, being in the switching valve usually an inlet throttle and in the control valve usually a drain throttle is integrated, through which to adjust a pressure ratio can flow on a piston of the respective switching valve fuel. The fuel flow through the outlet throttle of a control valve is through a valve body the respective control valve determines that with a valve seat of the same cooperates.
Im Betrieb einer Common-Rail Kraftstoffversorgungsanlage, insbesondere im HFO-Betrieb bei Kraftstofftemperaturen bis zu 150°C, unterliegen die Schaltventile sowie Steuerventile hohen Belastungen, die zu einem Verschleiß und frühzeitigen Ausfall derselben führen können. Insbesondere die Ventilsitze sowie Ablaufdrosseln der Steuerventile sind einem hohen Verschleiß durch Kavitation, Erosion und der mechanischen Belastung durch die Schaltvorgänge ausgesetzt. Die Steuerventile einer Common-Rail Kraftstoffversorgungsanlage sind demnach besonders verschleißanfällig.in the Operation of a common rail fuel supply system, in particular in HFO operation at fuel temperatures up to 150 ° C, subject the switching valves and control valves high loads, too a wear and tear early Failure of the same lead can. In particular, the valve seats and outlet throttles of the control valves are subject to high wear Cavitation, erosion and mechanical stress exposed by the switching operations. The control valves of a common rail fuel supply system are therefore particularly susceptible to wear.
Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zugrunde, eine neuartige Kraftstoffversorgungsanlage, nämlich eine neuartige Common-Rail Kraftstoffversorgungsanlage, einer Brennkraftmaschine sowie ein neuartiges Steuerventil zu schaffen.Of these, Based on the present invention, the problem is based a novel fuel supply system, namely a novel common rail Fuel supply system, an internal combustion engine and a to create a novel control valve.
Dieses Problem wird durch eine Kraftstoffversorgungsanlage einer Brennkraftmaschine gemäß Anspruch 1 gelöst.This Problem is a fuel supply system of an internal combustion engine according to claim 1 solved.
Erfindungsgemäß ist ein Ventilsitz für einen Ventilkörper der Steuerventile von einem Einsatz gebildet, der in einem Träger des jeweiligen Steuerventils aufge nommen ist und der eine größere Härte aufweist als der Träger des jeweiligen Steuerventils.According to the invention is a Valve seat for a valve body the control valves formed by an insert, which in a carrier of the respective control valve is taken and has a greater hardness as the carrier of the respective control valve.
Im Sinne der hier vorliegenden Erfindung wird vorgeschlagen, dass der besonders verschleißanfällige Ventilsitz der Steuerventile einer Common-Rail Kraftstoffversorgungsanlage von Einsätzen mit einer relativ großen Härte gebildet wird, die in Trägern mit relativ geringerer Härte aufgenommen sind. Die Träger mit relativ geringer Härte dienen der Anbindung der den Ventilsitz bildenden Einsätze an das jeweilige Steuerventil. Da der Träger lediglich über eine relativ geringe Härte verfügt, besteht keine Gefahr, dass der Träger bei der Montage beschädigt wird. Der im Träger aufgenommene Einsatz, welcher den Ventilsitz des jeweiligen Steuerventils bildet, ist bei der Montage keinen Belastungen ausgesetzt. Lediglich im Betrieb unterliegt der Einsatz der Steuerventile Belastungen, derselbe ist jedoch deutlich weniger verschleißanfällig, da er über eine relativ große Härte verfügt. Die Steuerventile der erfindungsgemäßen Kraftstoffversorgungsanlage sind demnach einem deutlich geringeren Verschleiß ausgesetzt, wodurch sich Kostenvorteile ergeben.in the For the purposes of the present invention, it is proposed that the particularly susceptible to wear valve seat the control valves of a common rail fuel supply system of inserts with a relatively large one Hardness formed that is in straps with relatively lower hardness are included. The carriers with relatively low hardness serve the connection of the valve seat forming inserts to the respective Control valve. As the carrier only one relatively low hardness features, There is no danger that the carrier will be damaged during assembly. The one in the carrier recorded insert, which the valve seat of the respective control valve forms is exposed during assembly no loads. Only In operation, the use of the control valves is subject to loads, However, the same is much less susceptible to wear, as it has a has relatively high hardness. The Control valves of the fuel supply system according to the invention are therefore exposed to significantly lower wear, which is Cost advantages arise.
Nach einer vorteilhaften Weiterbildung der Erfindung stellt der Einsatz neben dem Ventilsitz auch eine Ablaufdrossel des jeweiligen Steuerventils bereit.To an advantageous development of the invention is the use in addition to the valve seat and a drain throttle of the respective control valve ready.
Das erfindungsgemäße Steuerventil ist in Anspruch 10 definiert.The Control valve according to the invention is defined in claim 10.
Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung. Ein Ausführungsbeispiel der Erfindung wird, ohne hierauf beschränkt zu sein, an Hand der Zeichnung näher erläutert. Dabei zeigt:Preferred developments of the invention will become apparent from the dependent claims and the following description. An embodiment of the invention will be described, without being limited thereto, with reference to the drawing. Showing:
