Abstract

Conventional turbo compressors for internal combustion engines are driven by a mechanical connection. Compression of the intake air takes place downstream of the air filter. The solution according to the invention relates to an axial untreated air compressor having an electrical drive. The device can be positioned in an independent installation position to the internal combustion engine in the driving direction. The ram air flowing in through the air inlet (1) is compressed between the compressor (2) and the compressor housing (3) and is directed through the air filter (8) into the air outlet (12). A cover (6), which presses a pressure plate (5) against a reset force (7) in a diffusor (4), controls the charging pressure and enables the charge air to escape through the air slot (11). An electromagnetic converter (10) which is connected to a holder (9) regulates the speed of the rotors. The device is suitable for compressing untreated air and can be used in the automobile industry, especially in motorsports.

Description

[2.] Einrichtung zur Verdichtung der Ansaugluft vor dem Luftfilter einer Brennkraftmaschine.  [2.] Device for compressing the intake air in front of the air filter of an internal combustion engine.
[2.1.] Aufladeeinrichtungen für Brennkraftmaschinen erhöhen den Luftdurchsatz eines [2.1.] Charging devices for internal combustion engines increase the air flow rate of a
Verbrennungsmotors durch Vorverdichtung der zur Verbrennung des Kraftstoffs benötigten Luft. Durch den Einsatz von Aufladeeinrichtungen lassen sich höhere Leistungsdichten von Internal combustion engine by pre-compression of the air required for combustion of the fuel. Through the use of charging devices can be higher power densities of
Brennkraftmaschinen bei gleichbleibendem Hubraum, verbesserten Kraftstoffverbräuchen und niedriger liegenden Abgasemissionen erzielen. Achieve internal combustion engines with constant displacement, improved fuel consumption and lower exhaust emissions.
[2.1.1.] Bei mechanischen Ladern besteht eine mechanische Kopplung zwischen Lader und der Kurbelwelle der Verbrennungskraftmaschine. Die erforderliche Verdichtungsleistungeines mechanischen Laders wird folglich von der Leistung der Brennkraftmaschine abgezweigt. Bei den ferner als Ladern eingesetzten Abgasturboladern wird die zur Verdichtung der Luft erforderliche Verdichtungsleistung aus dem Abgas der Brennkraftmaschine gewonnen. Es besteht eine strömungstechnische Kopplung zwischen der Brennkraftmaschine, d. h. deren Auslasstrakt und dem Turbinenlaufrad des Abgasturboladers, welches seinerseits die Verdichterstufe des Abgasturboladers im Ansaugtrakt der Brennkraftmaschine antreibt. Bei Druckwellenladern, die einen elektrischen Antrieb zur besseren individuellen Ansteuerung in allen Betriebspunkten der Brennkraftmaschine aufweisen können, wird die zur Verdichtung der zur Verbrennung erforderlichen Luft nötige Verdichterleistung ebenfalls aus dem Abgas der [2.1.1.] Mechanical loaders have a mechanical coupling between the supercharger and the crankshaft of the internal combustion engine. The required compression capacity of a mechanical supercharger is consequently diverted from the power of the internal combustion engine. In the exhaust gas turbochargers also used as superchargers, the compaction power required for compressing the air is obtained from the exhaust gas of the internal combustion engine. There is a fluidic coupling between the internal combustion engine, d. H. the exhaust tract and the turbine wheel of the exhaust gas turbocharger, which in turn drives the compressor stage of the exhaust gas turbocharger in the intake tract of the internal combustion engine. In pressure wave superchargers, which may have an electric drive for better individual control in all operating points of the internal combustion engine, the required for compression of the air required for combustion air compressor power is also from the exhaust gas of the
Verbrennungskraftmaschine gewonnen. Internal combustion engine won.
[2.1.2.] Mit den erwähnten Aufladeeinrichtungen lässt sich grundsätzlich das Drehmoment kleinerer Verbrennungskraftmaschinen auf das Drehmomentniveau von Brennkraftmaschinen mit größerem Hubraum anheben. Abgasturbolader bieten durch den höheren effektiven Mitteldruck und durch Nutzung der Energie des Abgasstromes der Brennkraftmaschine zudem deutliche Verbrauchsvorteile. [2.1.2.] With the mentioned charging devices, in principle, the torque of smaller internal combustion engines can be increased to the torque level of larger displacement internal combustion engines. Exhaust gas turbochargers also offer significant fuel consumption advantages due to the higher effective mean pressure and the use of the energy of the exhaust gas flow of the internal combustion engine.
[2.1.3.] Es sind ferner elektrisch betreibbare Ladeluftverdichter bekannt, zum Anschluss an eine Brennkraftmaschine, welche einen Elektromotor mit einem Stator und einen Rotor zum Antrieb des Verdichterrades des Ladeluftverdichters umfassen. Das Verdichterrad ist in einem mit wenigstens einem Lufteinlass und einem Luftauslass versehenen Verdichterradgehäuse angeordnet. Der Lufteinlass und der Luftauslass sind über einen im Verdichtergehäuse verlaufenden Strömungskanal miteinander verbunden. Durch Drehung des Verdichterrades in einem Verdichtungsabschnitt des Strömungskanales wird eine Verdichtung der Ladeluft erzielt (EP1 520089 Bl). [2.1.3.] Furthermore, electrically operable charge air compressors are known, for connection to an internal combustion engine, which comprise an electric motor with a stator and a rotor for driving the compressor wheel of the charge air compressor. The compressor wheel is in one with arranged at least one air inlet and an air outlet Verdichterradgehäuse. The air inlet and the air outlet are connected to each other via a flow channel extending in the compressor housing. By rotating the compressor wheel in a compression section of the flow channel, a compression of the charge air is achieved (EP1 520089 Bl).
[2.1.4.] Außerdem ist ein Luftfilter für eine Brennkraftmaschine bekannt mit einem Gehäuse in dem ein Filtermitteleinsatz angeordnet ist, das Gehäuse weist einen Rohlufteinlaß und einen Reinluftauslaß auf. In dem Gehäuse ist ein von der Mündung des Reinluftauslasses her in den Reinluftraum sich erstreckendes Reinluftdämpferrohr vorgesehen, dieses weist an seiner [2.1.4.] In addition, an air cleaner for an internal combustion engine is known with a housing in which a filter medium insert is arranged, the housing has an unfiltered air inlet and a clean air outlet. In the housing a from the mouth of the clean air outlet forth in the clean air space extending pure air damper tube is provided, this points at his
Wandung Bohrungen auf. Das Reinluftdämpferrohr hat die Aufgabe, die Pulsationsschwingungen der Ansaugluft zu verringern. Da das Reinluftrohr einen bestimmten Durchmesser und eine bestimmte Länge aufweisen muß, um den gewünschten Effekt zu erzielen, ist der Bauraum für diese Anordnung erheblich. Gerade bei Anwendung einer Brennkraftmaschine in einem Fahrzeug ist es erforderlich den Bauraum des Ansaugtraktes möglichst gering zu halten. Wall holes on. The purpose of the clean-air damper tube is to reduce the pulsation vibrations of the intake air. Since the clean air tube must have a certain diameter and a certain length in order to achieve the desired effect, the installation space for this arrangement is considerable. Especially when using an internal combustion engine in a vehicle, it is necessary to keep the space of the intake system as low as possible.
[2.1.5.] Die Dl zeigt in der Figur 1 eine Brennkraftmaschine mit einem mehrstufigen Verdichter, der, wie aus Absatz [0030] bekannt, auch als Axialverdichter ausgeführt sein kann. [2.1.5.] The Dl shows in Figure 1 an internal combustion engine with a multi-stage compressor, which, as known from paragraph [0030], can also be designed as an axial compressor.

[2.1.6.] Aus der D2 ist aus der Figur 1 eine Brennkraftmaschine mit einem elektrisch [2.1.6.] From the D2 is from the figure 1, an internal combustion engine with an electric

[2.1.7.] Aus der D3 ist aus der Figur 1 eine Brennkraftmaschine bekannt, welche einen elektrisch angetriebenen Verdichter (12) und einem zweiten stromabwärts liegenden durch eine [2.1.7.] From the D3 of the figure 1, an internal combustion engine is known which an electrically driven compressor (12) and a second downstream by a

[2.1.8.] Aus D4 ist aus der einzigen Figur einen Anordnung bekannt, bei der ein Verdichter über einen Halter (17) mit dem Verdichtergehäuse (10) verbunden ist. (DE 10 2005 059 438 B3) [2.1.9.] Die Erfindung ist eine Einrichtung zum Verdichten der Ansaugluft, die sich vor dem Luftfilter einer Brennkraftmaschine befindet. Die innovative Lösung besteht darin, einen von der Brennkraftmaschine unabhängigen im Ansaugbereich hegenden Ansaugluftverdichter zu integrieren, der direkt vor einem konisch runden Luftfilter positioniert ist. Der mehrstufige Axialverdichter wird von einem Elektromotor angetrieben. Die Drehzahl wird in Abhängigkeit der Ansaugeschwindigkeit über eine Drehmomentregeier gesteuert. Um ein Stillstehen des Verdichters bei geschlossener Drosselklappenstellung zu verhindern, sorgt ein zusätzlicher Drehzahlschalter für ein Minimum an Drehzahl, damit kein Strömungsabriß an den [2.1.8.] From D4 is known from the single figure an arrangement in which a compressor via a holder (17) to the compressor housing (10) is connected. (DE 10 2005 059 438 B3) [2.1.9.] The invention is a device for compressing the intake air, which is located in front of the air filter of an internal combustion engine. The innovative solution is to integrate an intake-air compressor, independent of the engine, in the intake area, which is positioned directly in front of a conically round air filter. The multi-stage axial compressor is driven by an electric motor. The speed is controlled as a function of the intake speed via a torque vane. To prevent the compressor from stopping when the throttle position is closed, an additional speed switch ensures a minimum speed so that no stall occurs
Verdichterschaufeln entsteht. Der dabei entstehende Überdruck kann über eine Druckplatte, die gegen eine Rückstellkraft in das konisch runde Diffüsorgehäuse gedrückt wird, durch die Compressor blades is created. The resulting overpressure can via a pressure plate, which is pressed against a restoring force in the conically round Diffüsorgehäuse, through the
Lüftungsschlitze eines sich dahinter befindenden Deckel entweichen. Der Deckel ist mit dem Diffüsorgehäuse fest verbunden, der mit ringförmig angeordneten Lüftungsschlitzen ausgestattet ist. Auf diese Weise kann sicher gestellt werden, daß zu jedem Zeitpunkt und unabhängig der Drehzahl der Brerinkraftmaschine ausreichend Staudruck zur Verfügung steht. Die Steuerung der gesamten Einheit ist vom Steuergerät der Brennkraftmaschine unabhängig. Die Einrichtung kann daher nachträglich eingebaut werden und ersetzt den Luftfilterkasten. Die Stromzuführ für den Elektromotor erfolgt über den Generator der Brennkraftmaschine. Air vents escape a lid located behind it. The lid is firmly connected to the diffuser housing, which is equipped with ring-shaped ventilation slots. In this way it can be ensured that at any time and regardless of the speed of the Brerinkraftmaschine sufficient back pressure is available. The control of the entire unit is independent of the control unit of the internal combustion engine. The device can therefore be retrofitted and replaces the air filter box. The power supply for the electric motor via the generator of the internal combustion engine.
[2.2.] Die Ansaugluft wird direkt ausgehend vom Lufteiniass in den mehrstufigen Verdichter geleitet. Der Verdichter ist direkt vor dem konisch runden Luftfilter positioniert und erzeugt einen Staudruck. Mit dem im Anschluß des Verdichtergehäuse sich befindenden konisch runden Diffusorgehäuses wird die angestaute Ansaugluft beschleunigt und durch den Luftfilter in den Luftauslass geleitet. Ein weiterer Effekt, der genutzt werden kann, ist der durch den Fahrtwind entstehende Staudruck. Er addiert sich zum Ansaugluftdruck des in den Verdichter strömenden Luftflusses und steigert den Wirkungsgrad bei zunehmender Geschwindigkeit. Der [2.2.] The intake air is fed directly from the air aisle into the multi-stage compressor. The compressor is positioned directly in front of the conically round air filter and generates a back pressure. With the conical round diffuser housing located in the connection of the compressor housing, the accumulated intake air is accelerated and passed through the air filter into the air outlet. Another effect that can be used is the dynamic pressure created by the wind. It adds to the intake air pressure of the airflow flowing into the compressor and increases the efficiency with increasing speed. Of the
Drehmomentregler des Elektromotors regelt die Drehzahl proportional zur Ansauggeschwindigeit und des durch den Fahrtwind zusätzlich entstehenden Staudruckes. Dieser Effekt wird im Bereich des Motorsports genutzt. [2.2.1.] Die oben beschriebene und erfindungsgemäß vorgeschlagene Lösung eignet sich für aufgeladene und nicht aufgeladene Brennkraftmaschinen. Sie kann als Ergänzung dienen und den Wirkungsgrad der Brennkraftmaschine über den gesamten Drehzahlbereich verbessern. Ein weiterer Vorteil der vorgeschlagenen Lösung besteht darin, dass das Ansprechverhalten der Brennkraftmaschine beibehalten wird. Bei nicht aufgeladenen Brennkraftmaschine wird kein „Turboloch" erzeugt, lediglich das Drehmoment und die Leistung über den gesamten Torque controller of the electric motor regulates the speed proportional to the Ansauggeschwindigeit and the additional wind pressure due to the back pressure. This effect is used in the field of motorsport. [2.2.1.] The solution described above and proposed according to the invention is suitable for supercharged and non-supercharged internal combustion engines. It can serve as a supplement and improve the efficiency of the internal combustion engine over the entire speed range. Another advantage of the proposed solution is that the response of the internal combustion engine is maintained. When not supercharged engine no "turbo lag" is generated, only the torque and the power over the entire
Drehzahlbereich konstant erhöht. Bei aufgeladenen Brennkraftmaschinen werden die Speed range constantly increased. In supercharged internal combustion engines, the
Anfahrschwächen durch das höhere Drehmoment ab Leerlaufdrehzahl reduziert und das Starting weakness reduced by the higher torque from idle speed and the
Drehmoment so wie die Leistung über das gesamte Drehzahlband erhöht. Torque as the power increases over the entire speed range.
[2.2.2.] Ein weiterer Vorteil der Erfindung ist der entstehende Staudruck zwischen Verdichter und Verdichterghäuse. Der Staudruck hat eine dämpfende Wirkung auf die Ansaugluft und reduziert die Pulsationschwingung der Luftsäule im Ansaugtrakt. Die Statoren und Rotoren des Axialverdichters reduzieren zusätzlich die Pulsation der Ansaugluft durch die zugeführte Energie der Verdichterschaufeln. Ein weiterer Pulsationschwingungsabbau wird durch die bewegliche Druckplatte erzeugt, die einen Rückstau der Ansaugluft verhindert. Der Ansaugvorgang wird selbst bei geschlossener Drosselklappenstellung fortgeführt. Der dabei entstehende Überdrück im Diffusorgehäuse wird über die Druckplatte und den dahinter liegenden Deckel abgebaut. Die verdichtete Ansaugluft kann durch die ringförmigen Lüftungsschlitze des Deckels kontrolliert entweichen. [2.2.2.] Another advantage of the invention is the resulting dynamic pressure between compressor and compressor housing. The back pressure has a damping effect on the intake air and reduces the pulsation vibration of the air column in the intake. The stators and rotors of the axial compressor additionally reduce the pulsation of the intake air by the supplied energy of the compressor blades. Another Pulsationsschwingungsabbau is generated by the movable pressure plate, which prevents backflow of the intake air. The suction process is continued even when the throttle position is closed. The resulting overpressure in the diffuser housing is reduced via the pressure plate and the lid behind it. The compressed intake air can escape in a controlled manner through the annular ventilation slots of the lid.
[2.2.3.] Anhand der Zeichnung wird die Erfindung eingehender beschrieben. [2.2.3.] The invention will be described in more detail with reference to the drawing.

Die Verbinder zwischen Halter (9) und Verdichtergehäuse (3) sind in Einströmrichtung mit einem Leitwerksprofil versehen. Das Verdichtergehäuse ragt zu etwa 1/7 in das Diffüsorgehäuse (4) und ist am Ende mit einer Abrißkante ausgebildet.

Bewegungsrichtung der Ansaugluft sich verjüngt, kann sich die Ansaugluft nur zum Luftfilter (8) hin ausdehnen. Dadurch wird die Ansaugluft durch den Luftfilter gepresst und der Widerstand im Luftfilter (8) veringert sich dadurch relativ. Es entsteht ein Aufladeeffekt, der den Wirkungsgrad der Brennkraftmaschine steigert. Den Abschluß bilden die Druckplatte (5) mit dem Direction of movement of the intake air tapers, the intake air can only extend to the air filter (8) out. As a result, the intake air is forced through the air filter and the resistance in the air filter (8) is thereby reduced relatively. The result is a charging effect that increases the efficiency of the internal combustion engine. The conclusion form the pressure plate (5) with the
dahinterliegender Deckel (6), welcher mit dem konisch runden Diffüsorgehäuse (4) verbunden ist. Der Deckel( 6) weist am Rand ringförmig angeordnete Lüftungsschlitze (11) auf. Die Druckplatte (5) ist am äußeren Rand mit einem Konus versehen und wird über eine behind lid (6), which is connected to the conical round Diffüsorgehäuse (4). The lid (6) has at the edge annularly arranged ventilation slots (11). The pressure plate (5) is provided on the outer edge with a cone and is over a
Rückstellkraft (7) in das konisch runde Diffüsorgehäuse (4) gedrückt. Bei normalen Ansaugtakt wirkt der Konus der Druckplatte (5) wie eine Dichtung. Die Druckplatte (5) ermöglicht einen sofortigen Druckabbau im Diffüsorgehäuse (4) bei geschlossener Drosselklappenstellung. Ein Rückstau der Ansaugluft wird so verhindert. Die Ansaugluft entweicht durch die ringförmig angeordneten Lüftungsschlitze (11) des Deckels (6). Der Luftauslass (12) ist mit dem Deckel (6) verbunden und ist zugleich Halter für den Luftfilter(8) und dient ebenso als Führung für die Druckplatte (5). Durch den Luftauslass (12) wird die Ansaugluft als Reinluft schematisch durch zwei Pfeile dargestellt und zur Brennkraftmaschine geleitet. Restoring force (7) pressed into the conically round Diffüsorgehäuse (4). In normal intake stroke, the cone of the pressure plate (5) acts like a seal. The pressure plate (5) allows immediate pressure reduction in Diffüsorgehäuse (4) with closed throttle position. A backflow of the intake air is thus prevented. The intake air escapes through the annularly arranged ventilation slots (11) of the cover (6). The air outlet (12) is connected to the cover (6) and is at the same time a holder for the air filter (8) and also serves as a guide for the pressure plate (5). Through the air outlet (12), the intake air is shown as clean air schematically by two arrows and directed to the engine.
