Ausbildung des Zylinderkopfes und
der Zylinderkopfhaube von Einspritzbrennkraftmaschinen
Training of the cylinder head and
the cylinder head cover of fuel injection engines
Bei Einsprltzbrennkraftmaschinen mit hängend angeordneten Ventilen ist es "bekannt, auf dem Zylinderkopf Ventilantriebeglieder» wie Kipphebel, Druckstangen, Kipphebelwellen anzuordnen und den sog. Steuerraum nach oben hin durch eine Haube abzudecken, unter der noch die Kraftstoffleitungen, bei Dieselmaschinen die Kraftstoffzufuhrleitung (Einspritzleitung) und die Leckölleitung, zum im Zylinderkopf befestigten Einspritzdüsenkörper verlaufen. Das aus den Lagerungen und zwischen den Druck- bzw. Berührungsflächen der einzelnen Ventilantriebsglieder austretende Schmieröl sammelt sich auf dem Boden des Steuerraumes und fließt durch Bohrungen zur untenliegenden Schmierölwanne wieder ab. Beim Bruch der durch den Steuerraum verlaufenden Kraftstoffeinspritzleitung oder beim Leckwerden der in diesem Raum befindlichen Leitungeanschlüsse ergibt sich der Nachteil, daß sich dünnflüssiger Kraftstoff mit dem Schmieröl vermischt, wodurch eine ausreichende Schmierung der Lagerstellen der Brennkraftmaschine nicht mehr gewährleistet ist.In the case of injection internal combustion engines with valves arranged in a suspended manner, it is known "to have valve drive elements on the cylinder head» such as rocker arms, push rods, rocker arm shafts and to cover the so-called control room at the top with a hood, under which the fuel lines, In diesel engines, the fuel supply line (injection line) and the leakage oil line attached to the cylinder head Injector body run. That from the bearings and between the pressure or contact surfaces of the Lube oil escaping from individual valve drive elements collects on the floor of the control room and flows through bores to the lube oil pan below. When the fuel injection line running through the control chamber breaks or if the line connections located in this space leak, there is the disadvantage that low-viscosity fuel is mixed with the lubricating oil, which ensures sufficient lubrication of the bearing points Internal combustion engine is no longer guaranteed.
