Abstract

Bei einer Brennstoffeinspritzvorrichtung für Brennkraft­ maschinen mit einer Brennstoffzufuhrsteuereinrichtung und einem Einspritzventil, das einen an eine Brennstofförderein­ richtung über eine durch eine Brennstoffabsperrvorrichtung absperrbare Brennstoffzuleitung angeschlossenen Brenn­ stoffvorlageraum und eine mittels einer elektrohydraulischen Steuereinrichtung taktweise in Öffnungs- und Schließ­ stellung bewegbare Düsennadel aufweist, ist zur Über­ wachung der Tätigkeit und Feststellung eines Störungsfalles derselben erfindungsgemäß eine Düsennadelhub-­ Kontrolleinrichtung vorgesehen. Diese besteht aus einem mit der Düsennadel zusammenwirkenden Nadelhubindikator mit Steuerschaltung sowie einer daran angeschlossenen, ihrer­ seits mit einer Alarmeinrichtung und oder der Brennstoffab­ sperrvorrichtung verbundenen, elektronische Auswertor­ gane aufweisenden Überwachungseinrichtung. Die Überwa­ chungseinrichtung ist dabei in der Lage, praktisch alle an der Düsennadel und deren Bewegungsablauf möglicherweise entstehende, durch den Nadelhubindikator signalisierte Stö­ rungsfälle auszuwerten und im Störungsfalle ein Notstopp-­ Signal abzugeben, durch das entweder nur der oder die Zylin­ der mit dem eine defekte Düsennadel aufweisenden Ein­ spritzventil oder alle Zylinder der Brennkraftmaschine abschaltbar sind. Außerdem wird durch das Notstopp-Signal eine nachgeschaltete Alarmeinrichtung aktiviert, die exakt den Ort der Störung signalisiert und somit eine rasche Scha­ densbehebung vor Ort ermöglicht. In a fuel injector for internal combustion machines with a fuel supply control device and an injector that connects one to a fuel feed direction via a fuel shut-off device lockable fuel supply connected Brenn fabric storage room and one by means of an electro-hydraulic Control device cyclically in opening and closing position movable nozzle needle is for over monitoring of the activity and detection of a malfunction same according to the invention a nozzle needle stroke Control device provided. This consists of a with the needle stroke indicator interacting with the nozzle needle Control circuit and one connected to it partly with an alarm device and or the fuel locking device connected electronic evaluator gane having monitoring device. The monitor chungseinrichtung is able to practically all of the Nozzle needle and its sequence of movements possibly resulting disturbances signaled by the needle stroke indicator to evaluate cases of emergency and in the event of a malfunction an emergency stop Emit signal through which either only or the Zylin the one with a defective nozzle needle spray valve or all cylinders of the internal combustion engine can be switched off. In addition, the emergency stop signal a downstream alarm device activates the exact the location of the fault signals and thus a rapid Scha Eliminating the on-site enables.
