Abstract

Conventionally, the mixture is obtained by sucking air directly through the carburettor. This air flows at speeds of 0 to 700 m/sec depending on the speed of the motor so that the mixture is either too weak or too rich. A mixture chamber is added to the inlet pipe so that operation of the carburettor is more even over the whole range of operation of the engine. The chamber can also be used for two stroke engines in which case it is mounted between the carburettor and the inlet slot. The chamber is approximately oval section so that the speed of flow of the gas mixture is first reduced and then increased again.

Ich habe die Idee, dass eine Vorkammer zwischen Vergaser und Einlassventil entscheidene Vorteile Haben kann. Angefangen damit, dass eine weniger schwankende Luftgeschwindigkeit ein gleichbleibendes Gemisch hervorbringt, da diese Vorkammer einen Unterdruckausgleich zwischen den Ansaugzeiten schafft. Dadurch saugt sich die Vorkammer1 zwischen den Ansaugzeiten wieder voll und die nächste Ansaugphase hat je nach der Zahl des über diesen Vergaser gesteuerten Zylinder mehr oder weniger fertiges Gemisch zur Verfugung. Bei guter Abstimmung wäre Ansaugresonanz mit Gemischüberdruck möglich. Weiterhin bewirkt ein gleichmässigeres Gemisch eime reinere Verbrennung und dadurch weniger Schadstoffe. Mit einer gut ausgenutzten Resonanz wäre auch eine höhere Leistungsausbeute möglich. Dadurch ist bei gleichbleibender Leistung eine Kraftstoffersparnis nicht von der Hand zu weisen.I have the idea that an antechamber between the carburetor and the inlet valve can have decisive advantages. Starting with the fact that a less fluctuating air speed produces a constant mixture, as this antechamber creates a negative pressure compensation between the intake times. As a result, the antechamber 1 sucks up again between the intake times and the next intake phase has a more or less finished mixture available, depending on the number of cylinders controlled by this carburetor. With good coordination, intake resonance with excess mixture pressure would be possible. Furthermore, a more even mixture results in cleaner combustion and therefore fewer pollutants. With a well-used resonance, a higher power output would also be possible. As a result, fuel savings cannot be disregarded with the same performance.

PatentanspruchClaim Die Erfindung ist eine Vorkammer im Ansaugkanal von Benzinmotoren.The invention is an antechamber in the intake duct of gasoline engines. Zweck: Der Zweck der Vorkammer ist die Herstellung eines gleichbleibenden Gemisches für den Motor. Die Vorkammer wird zwischen den Ansaugzeiten von dem atmosphärischen Luftdruck mit Gemisch aufgefüllt, das dann für die nächste Verbrennung zur Verfügung steht.Purpose: The purpose of the antechamber is to produce a constant mixture for the Engine. The antechamber is exposed to atmospheric air pressure between the suction times filled with mixture, which is then available for the next combustion. Stand derState of Technik: Bisher ist es so, daß der Motor sich das Gemisch direkt durch den Vergaser holen muß und das dadurch die Ansauggeschwindigkeit vom Stillstand bis zu 7OO m pro Sekunde schwankt. So wird das Gemisch teilweise zu mager und fett.Technology: So far it has been the case that the engine has to get the mixture directly through the carburetor and that as a result, the suction speed fluctuates from standstill up to 700 m per second. This is how it will be Mixture partly too lean and rich. Aufgabe: Die Erfindung hat die Aufgabe, das GemischTask: The invention has the task of the mixture gleichbleibender Herzustellen und dadurch die Schadstoffe bei der Verbrennung zu verringern.to be produced more consistently and thus to reduce the pollutants during combustion. Lösung: Die Vorkammer ist für die Gemischaufbereitung in Form und Größe so zu wählen, daß eine über die gesamte Motorlaufzeit verlängerte Vergasertätigkeit gegeben ist.Solution: The antechamber is for the mixture preparation to be selected in shape and size in such a way that carburetor activity is prolonged over the entire running time of the engine given is. Oberbegriff:Generic term: Vorkammer im Ansaugkanal für Viertakt, Zweitakt und Wankelmotoren.Pre-chamber in the intake duct for four-stroke, two-stroke and rotary engines. Kennzeichnender Teil:Identifying part: dadurch gekennzeichnet, das eine Vorkammer zwischen Vergaser und Einlassventil bzw. Einlaßschlitz vorhanden ist.characterized in that there is an antechamber between the carburetor and the inlet valve or Inlet slot is present. 6098 12/04686098 12/0468
