Description
Intake System, in particular for an Internal Combustion Engine of a Vehicle The invention relates to an intake system, in particular for an internal combustion engine of a vehicle.
Intake systems for internal combustion engines of vehicles are well-known from the general prior art. Conventionally, such an intake system comprises at least one pipe which is also referred to as an air pipe. The pipe bounds at least one duct through which air can flow. Said air is guided to at least one combustion chamber of the internal combustion engine by means of the pipe and, thus, the intake system.
Moreover, it is known to use at least one compressor in such an intake system, wherein the compressor is configured to compress the air. Thereby, the combustion chamber of the internal combustion engine can be supplied with compressed air so that particularly high specific torque and power of the internal combustion engine can be realized.
It is an object of the present invention to provide an intake system by means of which a particularly advantageous air supply can be realized.
This object is solved by an intake system having the features of patent claims 1.
Advantageous embodiments with expedient developments of the invention are indicated in the other patent claims.
The intake system according to the present invention comprises at least one tube which bounds at least one first duct through which air can flow. The first duct is arranged on a first side of the tube. The tube further bounds at least one second duct through which air can flow, the second duct being arranged on an opposite side of the tube. In other words, the second side is opposite of the first side so that said ducts are separated from each other by means of the tube, for example, in the radial direction of the tube.
Furthermore, the intake system comprises a fan having a plurality of blades which are arranged in the second duct. The blades are configured to convey the air flowing through the second duct, wherein the fan is rotatable in relation to the tube about a rotation axis.
Additionally, the intake system according to the present invention comprises a motor configured to drive the fan about the rotation axis thereby conveying the air by means of the blades. In other words, by driving the motor about the rotation axis the blades are moved about the rotation axis in a rotational manner thereby conveying air through the second duct by means of the blades. Thus, air flow through the intake system can be multiplied or increased by means of the fan in such a way that the fan is driven about the rotation axis by the motor.
For example, the intake system according to the present invention can be used for an internal combustion engine so as to supply at least one combustion chamber of the internal combustion engine with the air flowing through the first duct and the second duct.
The intake system according to the present invention can provide a dual type flow providing at least two air flows. One of said air flows is a conventional air flow flowing through the first duct. The second air flow flows through the second duct, wherein the air flowing through the second duct can be conveyed and, for example, pressurized or accelerated by means of the fan driven by the motor. Thus, the internal combustion engine or its combustion chamber can be supplied with a particularly high amount of air in a need-based manner since the motor can be activated and deactivated in a need-based manner. By activating the motor the fan is driven by the motor so as to convey air through the second duct thereby supplying the combustion engine with a particularly high amount of air. Thus, the overall horsepower and torque of the engine can be improved.
Moreover, a compact design of the intake system according to the present invention can be realized since the installation space required by the tube, the motor and the fan can be kept particularly low. Moreover, the intake system according to the present invention can be used for aerospace applications, automobiles or another application where an air flow multiplier is needed. The intake system according to the present invention can be beneficial for driving different ways since horse power and torque can be improved.
Moreover, the vehicle mileage can be increased.
For example, the motor is configured as an electric motor, in particular a magnetic impulsion motor or a piezoelectric-based ultra-sonic motor or a conventional induction motor. Preferably the motor is configured as an internal rotor motor so that a particularly compact design of the intake system can be realized.
Further advantages, features, and details of the invention derive from the following description of a preferred embodiment as well as from the drawing. The features and feature combinations previously mentioned in the description as well as the features and feature combinations mentioned in the following description of the figures and/or shown in the figures alone can be employed not only in the respective indicated combination but also in other combination or taken alone without leaving the scope of the invention.
The drawing shows in: Fig. 1 a schematic sectional view of an intake system, in particular for an internal combustion engine of a vehicle, the intake system comprising at least one tube bounding two ducts, a fan having a plurality of blades configured to convey air through one of said ducts, and a motor configured to drive the fan; Fig. 2 a further schematic sectional view of the intake system; and Fig. 3 a schematic exploded view of the intake system.
In the figures the same elements or elements having the same functions are indicated by the same reference signs.
Figs. 1-3 show an intake system 10 which can be used for, for example, an internal combustion engine of a vehicle. The intake system 10 comprises a tube 12 which is used as a connecting element as will be described in the following. As can be seen from Figs. 1 and 2 the tube 12 bounds at least one first duct 14 through which air can flow. The first duct 14 is arranged on a first side 16 of the tube 12. Moreover, the tube 12 bounds at least one second duct 18 through which air can flow, wherein the second duct 18 is arranged on an opposite second side 20 of the tube 12. In other words, the second side is opposite of the first side 16 or faces away from the first side 16. The second duct 18 is bounded by the tube 12 in the radial direction of the tube 12 inwardly. Moreover, the first duct 14 is bounded by the tube 12 in the radial direction of the tube 12 outwardly.
The intake system 10 further comprises a fan 21 having a carrier 22 and a plurality of blades 24 mounted on the carrier 22. As can be seen from Figs. 1 to 3, the blades 24 are arranged on an inner circumferential surface 26 of the carrier 22, wherein the surface 26 faces towards the ducts 14 and 18. The second duct 18 is bounded by the carrier 22, in particular the inner circumferential surface 26 in the radial direction of the tube 12 outwardly. The blades 24 are configured to convey the air flowing through the second duct 18. The fan 21 is rotatable in relation to the tube 12 about a rotation axis 28 extending in the axial direction of the tube 12. Moreover, the intake system 10 comprises a motor 30 configured to drive the fan 21 and, thus, the carrier 22 and the blades 24 fixed to the carrier 22 about the rotation axis 28 thereby conveying the air through the second duct 18 by means of the blades 24. Thus, the air flowing through the second duct 18 can be accelerated or pressurized by means of the fan 21 so that the internal combustion engine or at least one combustion chamber such as a cylinder of the internal combustion engine can be supplied with a particularly high amount of air by the intake system 10.
The motor 30 is configured as an electric motor and comprises first magnets in the form of permanent magnets 32 arranged on the carrier 22. As can be seen from Figs. 1 to 3, the permanent magnets 32 are arranged on an outer circumferential surface 34 of the carrier 22, the outer circumferential surface 34 facing away from the inner circumferential surface 26 in the radial direction of the carrier 22 outwardly. Moreover, the motor 30 comprises second magnets in the form of electromagnets 36 arranged on a carrier 38 of the motor 30. The carrier 38 is a fixed stator element which can not be rotated about the rotation axis 28. Thus, the carrier 38 and the electromagnets 36 are a part of a stator of the motor 30. Moreover, the fan 21 and the permanent magnets 32 are pads of a rotor of the motor 30 which is configured as an internal rotor motor since the rotor is arranged inside the stator with respect to the radial direction of the motor 30.
The intake system 10 further comprises tubes in the form of pipes 40 and 42 which are also referred to as air pipes. The pipes 40 and 42 have respective ducts 44 and 46.
Moreover, the pipes 40 and 42 are attached to the tube 12. Thus, the pipes 40 and 42 are connected with each other via the tube 12. As can be seen from Figs. 1 and 2 the duct 44 isfluidically connected to the ducts 14 and 18 which are in turn is fluidically connected to the duct 46 so hat the ducts 44 and 46 are fluidically connected which each other via the ducts 14 and 18.
Moreover, the intake system 10 comprises a fixed base element 48 on which the fan 21 is rotationally supported by means of at least roller bearing. Preferably, the roller bearing is a ball bearing so as to keep friction between the base element 48 and the fan 21 particularly low. As can be seen from Figs. 1 and 2, the base element 48 is attached to the tube 12. Moreover, the carrier 38 is attached to the base element 48so that the pipes 40, 42, the tube 12, the base element 48, the carrier 38 and the electromagnets 36 are connected with each other in a fixed manner. Thus, the fan 21 and the permanent magnets 32 attached to the carrier 22 can be rotated in relation to the pipes 40, 42, the tube 12, the base element 48, the electromagnets 36 and the carrier 38 about the rotation axis 28.
Furthermore, the intake system 10 comprises a shutter device 50 comprising a plurality of shutters 52 and 54. In Figs. 1 and 2, directional arrows illustrate the flow of the air through the ducts 14 and 18. As can be seen from Figs. 1 and 2, the shutters 54 are arranged downstream of the shutters 52 with respect to the direction of flow of the air flowing through the intake system 10. Preferably, the shutter device 50, i.e. the shutters 52 and 54 are movably arranged on the tube 12 between the open position and the closed position.
The shutter device 50, i.e. the shutters 52 and 54 are movable between a closed position for closing the second duct 18 and at least one open position for opening the second duct 18 into the tube 12. Said closed position is shown in Fig. 1, wherein said open position is shown in Fig. 2. In the closed position the second duct 18 is blocked so that the air flowing through the intake system 10 cannot flow through the second duct 18. Thus, the internal combustion engine is supplied with air by the intake system 10 in a conventional manner. In order to increase the supply of the internal combustion engine with air, the shutter device 50 is opened and the motor 30 is activated thereby driving or rotating the fan 21 and, thus, the blades 24 about the rotation axis 28. Thereby, the air is conveyed through the second duct 18 in an active manner by means of the motor 30 and the blades 24, i.e. the fan 21. Since the shutter device 50 can be opened and closed in a need-based manner and since the motor 30 can be activated and deactivated in a need-based manner the internal combustion engine can be supplied with air in a need-based manner by the intake system 10. By opening the shutter device 50 and by activating the motor 30 the intake system 10 allows more air to enter the internal combustion engine.
With an increased air flow the internal combustion engine takes in greater amounts of oxygen into its combustion chambers allowing the vehicle to run better and also improving the vehicles mileage. Conventional intake systems have several twists and chambers which limit the air flow. This problem can be avoided by the intake system 10. The main objective of the intake system 10 is to allow the regular air flow through the first duct 14 and even with the motor 30 turned on and the shutter device 50 open. The internal combustion engine should act smoothly without any interruptions.
As can be seen from Fig. 3, the fan 21 is configured as a ring type fan, wherein, preferably, the blades 24 are configured as helical blades. Due to the ring type construction of the fan 21 the construction of the intake system 10 does not restrict or interrupt the normal air flow through the duct 14. The fan 21 and the motor 30 form a so-called multiplier by means of which air flow to the internal combustion engine can be multiplied or increased by activating the motor 30 and opening the shutter device 50.
When the multiplier is activated the shutter device 50 is opened and the motor 30 is activated so as to convey air through the second duct 18 while the air can still flow through the first duct 14 thereby creating a normal air flow. This normal air flow can mix with the pressurized or conveyed air thereby creating a high air flow to the intake system 10 to the internal combustion engine. For example, the motor 30 is configured as a magnetic impulsion motor, a piezoelectric-based ultra-sonic motor or a conventional induction motor, depending on the requirement.
When the multiplier is deactivated, the motor 30 is deactivated and the shutter device 50 is closed. During this deactivated state of the multiplier, the first duct 14 is still open so that air can still flow through the first duct l4so that the internal combustion engine can be still supplied with air. By activating the multiplier the amount of air and, thus, oxygen fed to the internal combustion engine can be increased with comparison to the deactivated state of the multiplier so that particularly high torque and power of the internal combustion engine can be realized.
Preferably, the shutter device 50, i.e. the shutters 52 and 54 are rotatable between the open position and the closed position. In particular, the shutter device 50, i.e. the shutters 52 and 54 are rotatable between the open position and the closed position about the rotation axis 28. Thus, a particularly compact design of the intake system 10 or the multiplier can be realized so that the installation space required by the multiplier can be kept particularly low.
