Definitions
- the invention relates to an intake system, in particular for the intake air of an internal combustion engine, with a filter insert and a plurality of intake ports, at least one of which can be closed with a flap, according to the preamble of the patent claim
- JP 6-159072 discloses an air filter system for an internal combustion engine, which has a plurality of intake ports 22, 24, 26 (cf. FIG. 1 of this document).
- the intake manifolds each open into further channel sections 44, 46, 48, in each of which air filter elements 50 are installed.
- flaps 62, 64, 66, 68, 70, 72 depending on the operating state of the internal combustion engine, the individual air filters and their associated intake ports can be switched on or off. This in particular allows the intake noise of the associated internal combustion engine to be reduced.
- the otherwise necessary volumes of the suction system, e.g. Shunt resonators can be omitted, which means that a smaller installation space is required for the intake system.
- the proposed solution also has disadvantages.
- the large number of flaps that can be switched individually and the use of several air filters means a high outlay on individual components, which makes the proposed solution problematic with regard to economical production.
- the different air filter elements are treated differently with filtrate depending on the switching of the flaps. This results in a different service life for each filter element, which means that they have to be replaced at different times. This also increases the operating costs of the intake system, which has a disadvantage for the operator.
- the object of the invention is to provide an intake system with a filter which has a small flow resistance in a small space, the
- the intake system according to the invention has several intake ports that open into the inlet of the filter housing. These can be at least partially closed with flaps, which can influence the acoustics of the intake system depending on the operating condition.
- the inlets all open into the same inflow space, the inflow space directly connecting to the filter insert of the Intake system adjoining
- a filter insert can be arranged in the inflow space.
- the common inflow space advantageously reduces the number of components used. Flow losses can also be reduced, since partition walls can be saved in the area of the common inflow space. Regardless of the flap position, that is, the number of closed intake ports, the fluid to be filtered can Distribute the inflow space freely so that it can then pass through the filter insert. A more even loading of the filter insert is possible, which means that the load of separated particles can be statistically distributed over the entire area of the filter insert. This increases the service life, since the one caused by the limit load Pressure drop at the filter element can be delayed. Due to the smaller number of components and the increased filter service life, the proposed solution is therefore particularly economical both in production and during operation
- the inflow space is wedge-shaped.
- the filter insert which in this case is flat, forms one side of the inflow space. This therefore narrows in accordance with the decrease in the volume flow that flows past the filter insert.
- This geometry is therefore particularly flow-efficient the fluid can flow through the intake system largely without detachment, which minimizes flow losses and the intake noise.
- such a geometry is also particularly space-saving because at all points the minimally necessary cross-section is made available in the inflow space, so that no unused volumes arise
- a further improvement in the flow properties in the intake system can be achieved if the inlets are all housed in the same housing wall section of the inflow space. These are then essentially parallel in their alignment, as a result of which a rectified flow of the fluid in the inflow space is achieved
- the said housing wall section can be rectangular, the inlets almost completely occupying the area of this wall section.
- the inlets are usefully also rectangular and arranged next to one another, except for the end faces of the inlets forming the inlets Walls of the intake manifold, the housing wall section is thus completely dissolved by the inlets.
- the filter insert is then at least essentially arranged opposite the inlets, so that the flow of the fluid is unhindered by d
- the filter insert can flow. This arrangement can be achieved in particular through the wedge-shaped inflow space mentioned above. In the case of a wedge-shaped inflow space, the filter is inclined to the inlets
- the intake manifold can contain connections which enable the filter housing to be connected to further channel structures, the channel structures forming the intake openings for the sucked-in fluid. These connections are preferably circular.
- sensors for the flap control on the intake system can detect the operating states of the intake system, from which the optimal flap position for the current operating state is determined. If the intake system is used for an internal combustion engine, the data for the flap position are made dependent on engine parameters These engine parameters, such as the engine speed, are determined outside the intake system.
- the flaps can be used for other auxiliary functions of the intake system.
- intake systems generally contain a warm air duct through which warm air can be drawn in at low temperatures. Branches in the intake system are usually provided for this purpose, which are usually actuated by mechanical thermal switches Effort can be saved if the duct system according to the invention, which is basically provided for generating acoustic effects, additionally fulfills these functions
- the individual intake openings of the different intake ports are led into different areas of the engine compartment.
- an intake opening can be provided in the area of the exhaust manifold from where warm air can be drawn in.
- the problem of undesired intake of rainwater or snow can be prevented if intake openings be provided in largely dry areas of the engine compartment, which can be used in the event that the filter insert becomes too moist or iced up
- a prerequisite for the function of the intake system according to the invention is that the entirety of the intake ports provides at least the cross section required for the maximum air requirement of the internal combustion engine.
- the inlets can be gradually closed off reduce the intake noise considerably
- the intake port that must always remain open can be designed without a flap
- the intake opening can be accommodated in different areas of the engine compartment from an acoustic point of view. This allows the intake noise to be changed depending on the switching of the flaps thus an increase in the intake noise as well as in operating conditions in which the driver cannot feedback via the engine noise
- the flaps In order to be able to produce the drive of the flaps economically, according to a special embodiment of the invention, they can be equipped with the properties of a permanent magnet, an electrical coil body being arranged in the area of influence of this magnetic field. The flaps can then be switched by current pulses in the coil body Complicated drives, such as, for example, electric motors or vacuum sockets, are eliminated. When using several flaps, the potential for saving this solution is considerable.
- the switching flaps used can be designed in accordance with DE 44 01 585 C 2
- the intake acoustics can be achieved if the intake system is provided with corresponding cavities in a manner known per se. These can be designed, for example, as shunt resonators and lead to a damping of the intake noise at certain frequencies or over a broadband range. The combination of all acoustic measures also allows this with limited installation spaces, the design of acoustically effective intake systems
- the modularity of the system supports the creation of modular systems.These can consist of identical parts, which can be combined depending on the application at hand.After the construction of an internal combustion engine has been completed, this structure can also be used to carry out acoustic measures which may be necessary if unexpected disturbing intake noises occur Certain frequency ranges occur Modules can be formed by different intake manifolds, the switching flaps, the filter inserts and different housing covers, which form acoustic cavities of different dimensions
- FIG 1 shows the schematic arrangement of an intake system in the engine compartment
- FIG. 2 shows a perspective view of the intake system with an air filter
- FIG. 1 an application for an intake system is shown schematically. It contains a housing 10 which is attached to an engine block 11 of an internal combustion engine. Hoses 12 a, b, c lead to inlets 13 on the housing and thus form intake manifolds
- Hose 12 a mouths in the upper part of the engine compartment in a splash-proof area, so that dry intake air can be sucked through this even in damp weather conditions
- Hose 12 b extends into the lower area of a bumper 16 of a vehicle
- the housing 10 is of modular construction. It has a cuboid basic shape, a filter insert 19 being installed along a diagonal of the interior of the housing body. This divides the interior into an inflow space 20 and an outflow space 21
- the combustion air flows through three inlets 13, one of which can be seen in the cut intake 14, into the inflow space 20, which corresponds to After the decrease in the volume flow from the inlets towards the opposite side of the housing 10 tapered in a wedge shape, the volume flow decreases there because the filter insert 19 is traversed by the intake air, which in this way arrives in the wedge-shaped discharge space 21.
- the air masses increase - flows in the direction of an outlet 22 and leaves the housing 10 through it
- All inlets 13 are arranged in a housing wall section 23, which at the same time forms the end face of the wedge-shaped inflow space 20.
- the flow of the intake air can therefore reach the inflow space 20 without a diversion directly into the inflow space 20.
- the two outer intake ports are provided with flaps 24, with the latter Help they can be opened or closed
- the flap drive consists of bobbin 25, which surround the suction port 14 provided with a flap and are connected to a power supply 26.
- the middle intake manifold has no flap. In the event that the other two intake manifolds are closed by the flaps, the flow of the intake air is thus directed through the central intake manifold. From there it can be distributed in the inflow space 20 without significant flow losses
- the intake manifolds consist of a fixed part integrated into the housing 10, which has a connection 27. As shown on the central intake manifold, this part can be used as a suction opening 15. Another possibility is to plug a hose 12a onto the connection, which is a The intake opening 15 is then formed by the hose end. Alternatively, of course, additional duct structures made of plastic can also be adapted to the connection.
- the system thus has a modular structure and can be adapted to engine compartments of different dimensions
- the modular construction of the housing 10 also permits the adaptation of further acoustic devices, for example shunt resonators 28.
- shunt resonators 28 each consist of covers 29 which, with the interposition of a partition wall 30, form the bottom surfaces of the housing 10.
- the partition walls have openings 31 of different geometry, in order to influence the acoustic behavior of the shunt resonators. sen.
- the resonator volume and thus its acoustic behavior can also be influenced by providing different covers, which pay particular attention to the installation space for the housing.
- inflow chamber 20 there is also a water sensor 32, the signal of which can be used to close inlets 13 in damp weather conditions, in which the risk of water being sucked in is particularly great.
