Abstract
Die Erfindung betrifft ein Verfahren zur Beeinflussung des Verbrennungsvorganges einer Brennkraftmaschine mit einem Ansaugsystem für die Luft, wobei in dem Ansaugsystem eine gesteuerte Querschnittsverengung derart durchgeführt wird, dass eine Modulation der Strömung erzeugt wird (Figur 1).The invention relates to a method for influencing the combustion process of an internal combustion engine with an intake system for the air, a controlled cross-sectional constriction being carried out in the intake system in such a way that a modulation of the flow is generated (FIG. 1).
Description
Die Erfindung betrifft ein Verfahren zur Beeinflussung eines Verbrennungsvorganges einer Brennkraftmaschine mit einem Ansaugsystem für die Luft.The invention relates to a method to influence a combustion process of an internal combustion engine with an intake system for the air.
Bei den heute bekannten Brennkraftmaschinen strömt die Luft konstant durch das Ansaugsystem. Eine variable Veränderung des Querschnitts des Ansaugsystems findet nicht statt.In the internal combustion engines known today flows the air constant through the intake system. A variable change of the cross section of the intake system does not take place.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Verfügung zu stellen, bei dem durch gezielte Veränderung der Strömung der Luft im Ansaugsystem einer Brennkraftmaschine eine Motormanagement vorgenommen werden kann.The invention is based on the object Procedures available to ask, by changing the flow of the Air in the intake system of an internal combustion engine engine management can be made.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This task is characterized by the Features of claim 1 solved.
Weiterbildungen erfolgen gemäß den Merkmalen der Unteransprüche.Further training takes place according to the characteristics of subclaims.
Gemäß der Erfindung wird durch eine gesteuerte Querschnittsverengung im Ansaugsystem eine Strömungsmodulation erzeugt. Mit dieser regel- oder steuerbaren Verengung lässt sich der Volumenstrom der Luft gezielt beeinflussen.According to the invention is by a controlled cross-sectional narrowing in the intake system a flow modulation generated. With this adjustable or controllable constriction specifically influence the volume flow of the air.
Auf diese Weise kann ein gezieltes Motormanagement vorgenommen werden. Durch die Strömungsmodulation können gleichzeitig die Ansauggeräusche gedämpft werden. Außerdem können Geräusche gezielt erzeugt bzw. gedämpft werden, so dass am Motor bzw. dem Verbrennungsprozess ein Sound-Design vorgenommen werden kann.In this way, a targeted Engine management can be made. Through flow modulation can at the same time the intake noises muted become. Moreover can Sounds specifically generated or damped be so that a sound design on the engine or the combustion process can be made.
Durch die gezielte Beeinflussung des Verbrennungsprozesses ist auch eine Verringerung des Treibstoffverbrauches möglich. Die Querschnittsverengung im Ansaugsystem kann mit einer Steuereinheit gesteuert oder mit einer Regeleinheit geregelt werden.Through targeted influencing the combustion process is also a reduction in fuel consumption possible. The cross-sectional constriction in the intake system can be done with a control unit controlled or regulated with a control unit.
Die Querschnittsverengung wird durch

Gemäß einer anderen Ausführungsform der Erfindung wird die Luft zunächst ionisiert und durch ein nachgeschaltetes Magnetfeld eine Querschnittsverengung vorgenommen.According to another embodiment the invention is air first ionized and a cross-sectional narrowing due to a downstream magnetic field performed.
Die Erfindung wird nachfolgend anhand zweier Ausführungsbeispiele näher beschrieben.The invention is described below with reference to two embodiments described in more detail.
