Abstract
Ein bekannter Drallklappenflansch für Brennkraftmaschinen weist ein aus einer Drosselwelle und Klappen gebildetes Abgasrückführsystem auf. Dieses ist sehr aufwendig herzustellen und weist eine Luft-Ausgleichströmung zwischen Luftansaugkanälen auf, die Leistungsverluste bewirkt. Hiergegen sieht die Erfindung vor, dass jedes Steuerventil (4) von einem Drehschieber (6) gebildet ist, der an seiner Außenstirnfläche (7) einen Hebelzapfen (8) aufweist, und daß jeder Hebelzapfen (8) in eine gemeinsame Betätigungsstange (9) eingehängt und durch ein Verstellelement (10) gemeinsam verstellbar ist. Der neue Drallklappenflansch ist preiswert und wirkt leistungssteigend.A known swirl flap flange for internal combustion engines has an exhaust gas recirculation system formed from a throttle shaft and flaps. This is very expensive to produce and has an air-compensating flow between air intake ducts, which causes power losses. Against this, the invention provides that each control valve (4) by a rotary valve (6) is formed, on its outer end face (7) has a lever pin (8), and in that each lever pin (8) mounted in a common operating rod (9) and by an adjusting element (10) is adjustable together. The new swirl flap flange is inexpensive and has a higher performance.
Description
Die Erfindung betrifft einen Drallklappenflansch für eine Anordnung an einem Zylinderkopf einer Brennkraftmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a swirl flap flange for an arrangement on a cylinder head of an internal combustion engine according to the preamble of patent claim 1.
Es ist bereits bekannt (
Insbesondere beim Dieselmotor oder Benzindirekteinspritzmotor haben sich neue Möglichkeiten der Abstimmung von Drall und Zylinderfüllmengen ergeben, wobei sich bei bisher üblichen Abgasrückführsystemen grosse Volumina ihrer Abgasrückführkanäle als störend erwiesen haben.Especially in the case of the diesel engine or gasoline direct injection engine, new possibilities have been found for the coordination of swirl and cylinder charge quantities, with large volumes of their exhaust gas recirculation passages having proved to be troublesome in previously customary exhaust gas recirculation systems.
Es waren daher Massnahmen aufzufinden, mit denen ein gattungsgemässes Abgasrückführsystem im Zusammenhang mit einem Luftansaugkanalsystem für Diesel- oder Benzindirekteinspritzmotoren betrieben werden kann, wobei sich die Anforderungen an niedrige Schadstoffemissionen erfüllen lassen müssen.It was therefore to find measures with which a generic exhaust gas recirculation system can be operated in conjunction with an air intake duct system for diesel or gasoline direct injection engines, which must meet the requirements for low pollutant emissions.
Aus der nicht vorveröffentlichten
Diese Ausführung ist technisch aufwendig und es besteht ein erheblicher Teile- und Montageaufwand. Darüber hinaus wurde festgestellt, daß über die Lagerabschnitte der Drosselwelle eine durch die Ansaugfolge in den einzelnen Luftansaugkanälen verursachte Luft-Ausgleichsströmung erfolgt, die das Leistungsverhalten der Brennkraftmaschine negativ beeinflußt.This design is technically complex and there is a considerable part and assembly costs. In addition, it has been found that over the bearing portions of the throttle shaft caused by the intake in the individual Luftansaugkanälen air-compensating flow takes place, which adversely affects the performance of the internal combustion engine.
Hiervon ausgehend ist es daher Aufgabe der Erfindung, einen Drallklappenflansch mit einem Abgasrückführsystem zu gestalten, der gegenüber dem Stand der Technik mit geringerem Aufwand herstellbar ist und die Leistungsabgabe der Brennkraftmaschine nicht beeinflußt.On this basis, it is therefore an object of the invention to design a swirl flap with an exhaust gas recirculation system, which can be produced with less effort compared to the prior art and does not affect the power output of the internal combustion engine.
Diese Aufgabe ist durch die im Kennzeichen des Patentanspruchs 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterizing part of patent claim 1.
