Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Es sind Einblaseluftsteuerungen bekannt, bei welchen zwei oder mehrere Brennstoffdüsen vorhanden sind. Bei vorliegender Erfindung sind die Brennstoffdüsen mit je einem besonderen Brennstoffkanal in Verbindung, und diese Brennstoffkanäle sind alle direkt oder durch Bohrungen mit einem einzigen am Zylinderkopf oder in einem an diesem befestigten Einsatzstück gelagerten Einblasefrischluftventil verbunden, so daß beim Eröffnen dieses Einblaseventils die Luft durch alle Bohrungen zu den Brennstoffkanälen und durch diese zu den Düsen und in den Zylinder strömen kann. Man kann nun durch ein Absperrorgan zeitweilig einen Brennstoffkanal oder die Bohrung zum Kanal absperren oder öffnen, um bei großer Belastung oder beim Anlassen der Maschine oder wenn es sonst als nötig erachtet wird, mit einem, zwei oder mit mehreren Brennstoffkanälen und Düsen arbeiten zu können.Injection air controls are known in which two or more fuel nozzles available. In the present invention, the fuel nozzles are each with one particular fuel channel in connection, and these fuel channels are all direct or through holes with a single one on the cylinder head or in one attached to it Insert connected to the intake fresh air valve, so that when it is opened this injection valve the air through all holes to the fuel channels and can flow through this to the nozzles and into the cylinder. You can now temporarily open a fuel channel through a shut-off device or the hole to the channel to shut off or open to in case of heavy load or when starting the machine or when there is otherwise deemed necessary with one, two or more fuel channels and Nozzles to be able to work.

Die Zeichnung stellt z. B. eine derartige Einrichtung mit zwei Einspritzdüsen dar. b bezeichnet das Einblaseluft ventil, α die zweiThe drawing represents z. B. represents such a device with two injection nozzles. B denotes the air injection valve, α the two

25· Düsen, f die zwei Brennstoffkanäle, welche jeweils mittels einer Bohrung e mit dem Einblaseluftventil in Verbindung stehen. Das Einblaseluftventil wird von der Steuernocke c angetrieben. Beim Eröffnen des Ventils b strömt die Einblaseluft durch die Bohrungen e nach den Brennstoffkanälen f, wo sie hinter den Brennstoff tritt und diesen durch die Düsen α nach dem Verbrennungsraum treibt.25 · Nozzles, f the two fuel channels, which are each connected to the air injection valve by means of a bore e. The air injection valve is driven by the control cam c. When the valve b is opened , the injection air flows through the bores e to the fuel channels f, where it passes behind the fuel and drives it through the nozzles α to the combustion chamber.

Bei kleinen Belastungen oder Betriebsverhältnissen, wo nur eine Brennstoffdüse nötig ist, werden durch ein Absperrventil d die anderen Kanäle abgesperrt, so daß diese eine Düse nur während der Inbetriebsetzung oder nur dann in Wirkung tritt, wenn es als erforderlich erachtet wird.In the case of low loads or operating conditions where only one fuel nozzle is required, the other channels are shut off by a shut-off valve d so that this one nozzle only comes into effect during start-up or only when it is deemed necessary.

Die Düsen α können derart schräg zueinander gebohrt werden, daß sich die beiden Brennstoffstrahlen im Verbrennungsraum treffen, wodurch eine bessere Zerstäubung des Brennstoffes und daher auch eine bessere Verbrennung herbeigeführt wird.The nozzles α can be drilled at an angle to one another in such a way that the two fuel jets meet in the combustion chamber, which results in better atomization of the fuel and therefore also better combustion.

Bei dieser Einrichtung können zwei oder auch mehrere Brennstoffkanäle von einem einzigen Einblasefrischluftventil bedient werden.In this device, two or more fuel channels can be from a single one Injection fresh air valve can be operated.
