The present invention relates to according to the throttling arrangement of the preamble of claim 1 and according to the internal-combustion engine of the preamble of claim 14.
Background technique
In automotive engineering, the air quantity that is used to burn that offers internal-combustion engine is controlled and/or regulated, so that can control and/or regulate the mechanical output of exporting by internal-combustion engine thus by a throttling arrangement that is arranged in the sucking pipe.On the internal-combustion engine of modern times and low oil consumption, use the little throttling arrangement of air throttling, so that further reduce fuel consumption to the input internal-combustion engine much more more and more.These internal-combustion engines for example are internal-combustion engine and/or HCCI (evenly charge compression ignition) internal-combustion engine of working method or the internal-combustion engine of stratified mixture combustion that is provided with the minification of turbosupercharger.Need low pressure to come work for the various technique devices in the automobile, for example combustion intensity booster and/or tank ventilation system.But low pressure provides more difficult under little situation that the air throttling that flows to internal-combustion engine by throttling arrangement is healed.
And use additional low pressure pump to provide low pressure system that shortcoming is arranged, because need the optional feature of low pressure pump form and the mechanical output that low pressure pump consumes internal-combustion engine.Also can in the bypass channel of the through-flow channel of the throttling flap that is provided with throttling arrangement, use independent jet pump.But this jet pump must use solenoid valve to connect and cut out unfriendly, so that do not disturb unloaded the adjusting.
But low pressure pump also electricity consumption drives, but this must provide electric current by the automobile electrical network unfriendly.This also with directly absorb mechanical energy from internal-combustion engine and drive low pressure pump and interrelate with high fuel consumption similarly.
EP 0 482 272 B1 provide the volume flow control valve of the valve chest that is provided with the band penetration channel, this penetration channel is limited by an interface, can flow along this interface, and this valve is provided with a valve body that can rotate around axle in passage, wherein valve body shows as a circumferential surface, zone on a preposition of valve body in this circumferential surface and interface be in tight contact and the tight contact on the precalculated position by this precalculated position in the face of respective shapes guarantee that wherein valve body is that a throttling flap and this passage are set in the throttling flap housing.
Summary of the invention
According to of the present invention be used for automobile be used for that to change to be that the throttling arrangement of the air quantity that imports of internal-combustion engine comprises by sucking pipe: at least one movable throttling bodies can change by the motion of at least one throttling bodies so that be used for importing the through flow cross section of through-flow channel of the air of internal-combustion engine at the throttling arrangement place; A housing, the through-flow channel that is particularly useful for receiving at least one movable throttling bodies and is particularly useful for limiting the throttling arrangement place, wherein throttling arrangement is provided with a low-voltage tube, so that-be preferably in the throttle position of at least one throttling bodies-at least one throttling bodies place forms in through-flow channel low pressure can derive by through-flow channel by low-voltage tube.
Only feed in the through-flow channel that has at least one movable throttling bodies in the housing at an additional configuration mesolow pipe.
A distance that feeds through-flow channel in the complete closed position of an additional configuration mesolow pipe at least one movable throttling bodies is less than 3cm, 2cm, 1cm or 0.5cm.
Conform with the destination, throttling arrangement has a little through-flow mouth in the complete closed position of at least one throttling bodies, for example be used for no-load running.
Low-voltage tube especially passes periphery and/or the low-voltage tube that housing leads to housing by through-flow channel and feed through-flow channel in the zone of at least one throttling bodies.
Throttling arrangement and/or internal-combustion engine have a device that is used to store low pressure in an additional configuration.
In another form of implementation when at least one throttling bodies moved by complete closed position less than 30%, 20% or 10% of the complete whole motion possibility between closed position and the fully open position reach one when partially opening the position in the increase of the through flow cross section of low-voltage tube place through-flow channel basically corresponding to the increase of the minimum through flow cross section at least one throttling bodies place.
Therefore this throttling arrangement also can provide low pressure on the bigger load area and not only in closed position fully the time.Throttling arrangement only has very little through-flow mouthful when complete closed position, and internal-combustion engine can be supplied to little air quantity in no-load running thus.In an open position, promptly through-flow mouthful of throttling arrangement when partially opening the position increases and more air can flow through throttling arrangement when at least one throttling bodies is moved to by complete closed position.Basically corresponding to the increase of the minimum through flow cross section at least one throttling bodies place, its deviation is less than 40%, 30% in other words based on the increase of the through flow cross section of the geometric profile low-voltage tube place through-flow channel of at least one throttling bodies, and 20%, 10% or 5%.Therefore as the through flow cross section at least one throttling bodies place of minimum through flow cross section basically corresponding to the through flow cross section of low-voltage tube place through-flow channel.Exert sharp equation along with the pressure on the through-flow mouth of the increase of speed air flow will reduce based on one hundred.
If minimum through flow cross section, promptly little a lot of than the through flow cross section of low-voltage tube place through-flow channel at through-flow mouthful minimum through-flow mouthful through flow cross section of the conduct at least one throttling bodies place, then at minimum through flow cross section place, promptly form a very little or minimum low pressure at least one throttling bodies place, but during this relatively little low pressure only is formed on around the big through flow cross section in low-voltage tube place very little.
Here situation is not such, because the through flow cross section of low-voltage tube place through-flow channel is basically corresponding to the minimum through flow cross section at throttling bodies place, even so that also appear at the low-voltage tube place basically and therefore big relatively when partially opening the position and on big loading range, also can provide enough big low pressure thus by this throttling arrangement in the low pressure that occurs on the minimum through flow cross section at least one throttling bodies place.Thereby by this throttling arrangement not only when the zero load or in extremely strong cutting condition, and all can provide enough low pressure in the partial load scope of very frequent appearance on the internal-combustion engine of automobile.
In an additional configuration, moved less than 30% of whole motion possibility by the direction of complete closed position to the fully open position at least one throttling bodies, 20% or 10% one partially opens that the through flow cross section in low-voltage tube place through-flow channel has basically-promptly less than 30% in the position, 20%, 10% or 5% deviation ground-corresponding to the through flow cross section of at least one throttling bodies place as minimum through flow cross section.
In an additional form of implementation throttling arrangement have two can be mutually oppositely around the throttling roller of spin axis deflection as throttling bodies.
Two throttling rollers are preferably in the next door that is positioned at a supporting surface in the throttle position mutually.
In another program at the low-voltage tube place minimum through flow cross section appears in each throttle position of two throttling rollers.
Structure has a through flow hole between two throttling rollers in a scheme, and wherein the through flow cross section of this through flow hole can change around the deflection of spin axis by two throttling rollers.
It is bigger to conform with the destination through flow hole, heals little and also anti-otherwise supporting surface is parallel to the extended length of spin axis.
To be parallel to a cross section of spin axis be that circle or ellipse and/or low-voltage tube feed through flow hole between two throttling rollers to through flow hole in another form of implementation.
Especially at least one throttling bodies is configured the throttling flap.
The throttling flap can be rotated axis around spin axis deflection and throttling flap and is divided into first and second throttling flap part in another configuration.
The throttling flap has a thickening and is formed in carrying on the side of opening sense of rotation of first and/or second throttling flap part opening on the sense of rotation for the through flow cross section first that increases throttling arrangement and/or the thickening on the second throttling flap part of throttling flap in an additional project.Since throttling flap structure have thickening at a through flow cross section that partially opens mesolow pipe place, position through-flow channel basically corresponding to the minimum through flow cross section at throttling flap place, so that on one of internal-combustion engine wide loading range, also can provide enough big low pressure partially opening in the position of throttling flap by this throttling arrangement, because minimum through flow cross section is basically corresponding to the through flow cross section at low-voltage tube place.
In another program when the throttling flap moved by complete closed position less than 30%, 20% or 10% of the complete whole motion possibility between closed position and the fully open position reach one when partially opening the position in the increase of the through flow cross section at low-voltage tube place basically corresponding to the increase of the minimum through flow cross section in throttling flap place.
Throttling arrangement is provided with a movement means that is used at least one throttling bodies in another configuration, for example a motor and/or a transmission device.
Internal-combustion engine according to the present invention is provided with an air that is used for burning usefulness and imports the sucking pipe of internal-combustion engine and throttling arrangement that is installed in sucking pipe with control and/or regulate the air quantity that can be imported by sucking pipe, and wherein this throttling arrangement is constituted as the throttling arrangement described in this patent application.
Be constituted as hole in a low pressure port or hole, the especially housing at an additional form of implementation mesolow pipe.
Throttling arrangement comprises a bearing that is used at least one movable throttling bodies in another configuration.

Through flow hole 6 increases when two throttling rollers 3 are moved to first portion open position according to Fig. 2 and 6 by the complete closed position according to Fig. 1 and 5.By complete closed position in this motion of first portion's open position in Fig. 6 the throttling roller 3 shown in the right side move in the clockwise direction and reaches that the throttling roller 3 shown in the left side moves in the counterclockwise direction in Fig. 6.Be positioned at supporting surface 5 next doors mutually at two throttling rollers 3 of this situation, so that two throttling rollers 3 carry out rotational motion around spin axis 7 on opposite sense of rotation when opening or closing.Because the geometric profile of groove 10 through flow hole 6 of air in the case increases.Here low-voltage tube 8 feeds throttle orifice having on the position of minimum through flow cross section.The whole through flow cross section (Fig. 6) that the air that guides by throttling arrangement 1 all has through-flow channel 14 in the front and the back of two throttling rollers 3.Air fed through flow cross section is reduced to minimum through flow cross section in the zone of two throttling rollers 3 of layout in through-flow channel 14, as shown in Figure 2.Then the back of two throttling rollers 3 provides the through flow cross section of air to increase to the through flow cross section of through-flow channel 14 again on the air ventilation direction.Minimum in the case or minimum low pressure appears at has minimum or on the position of narrow through flow cross section.Low-voltage tube 8 also is arranged on this position, thus by low-voltage tube 8 can be outwards with should minimum or minimum possible low pressure export in the periphery 16 of throttling arrangement 1.Therefore in the scope of the partial load of internal-combustion engine 20, also can provide enough low pressure by throttling arrangement 1.This also is applicable to the second portion open position of two throttling rollers 3 shown in Fig. 3 and 7 in a similar fashion.
The position of opening fully of Fig. 4 and two throttling rollers 3 of 8 expressions.Two throttling rollers 3 no longer reduce through-flow channel 14 in this position through flow cross section and air can flow by throttling arrangement 1 on without hindrance not throttling ground.The through flow cross section of through-flow channel 14 is preferably corresponding to the cross section (Figure 12) of sucking pipe 21 in the case.
Second embodiment of expression throttling arrangement 1 among Fig. 9 to 11.Throttling arrangement 1 only has a throttling flap 4 and is used as throttling bodies 2.Throttling flap 4 can be around spin axis 7 deflections by motor 19 and a transmission device 18 as movement means 17.Here spin axis 7 is perpendicular to the drawing of Fig. 9 to 11.Throttling flap 4 has the first throttle flap part 11 and the second throttling flap part 12.Be provided with a thickening 13 or block in first and second throttling flap part 11,12.Here thickening 13 is arranged on carrying of first and second throttling flap part 11,12 and opens on the side of sense of rotation.Opening sense of rotation in the case is the sense of rotation that is used to increase through flow cross section of throttling flap 4, promptly for example when throttling flap 4 by complete closed position shown in Figure 9 deflect into shown in Figure 10 partially open the position time sense of rotation or on the direction of the fully open position shown in Figure 11.Here through-flow channel 14 limit by the housing 15 of throttling arrangement 1 and on housing 15 structure a low-voltage tube 8 or a low pressure hole 9 are arranged.Low pressure can be exported to the periphery of throttling arrangement 1 by through-flow channel 14 by this low-voltage tube 8 or low pressure hole 9.
Expression has the very complete closed position of the throttling flap 4 of the through-flow mouth 6 of circlet shape among Fig. 9.Here low-voltage tube 8 feeds through-flow channel 14 in this wise: be in the through flow cross section that constitutes minimum between throttling flap 4 and the housing 15 at low-voltage tube 8 or low pressure hole 9.Minimum or minimum low pressure also occur at this minimum through flow cross section place, this low pressure can export to peripheral 16 by low-voltage tube 8.On low-voltage tube 8, for example can connect a unshowned flexible pipe, so that low pressure for example be offered a tank ventilation system of a combustion intensity booster or automobile 22 by this unshowned flexible pipe.
When throttling flap 4 in the clockwise direction by the complete closed position shown in Fig. 9 move to shown in Figure 10 partially open the position time increased minimum through flow cross section.Minimum through flow cross section is indicated by A in Figure 10.It minimum through flow cross section occurring corresponding to a position between first throttle flap part 11 and housing 15 on this position.
Low-voltage tube place by the B indication among this external Figure 10 also has through flow cross section.Here at this through flow cross section B at low-voltage tube 8 places corresponding at the housing 15 at low-voltage tube 8 or 9 places, low pressure hole and the through flow cross section between the first throttle flap part 11.Because structure has thickening 13 through flow cross section B only less times greater than minimum through flow cross section A on first throttle flap part 11.Therefore at the through flow cross section B at low-voltage tube place basically corresponding to minimum through flow cross section A.Thereby exert sharp equation because a little littler speed air flow only appears than minimum through flow cross section A place in only big a little the through flow cross section B of minimum relatively through flow cross section A at low-voltage tube 8 places based on one hundred.Only occur bigger a little low pressure thus at low-voltage tube 8 places, so that also also can provide enough low pressure for load in the partial load zone at internal-combustion engine 20 thus by throttling arrangement 1 with low pressure requirements partially opening in the position of throttling flap 4 than minimum through flow cross section A place.
The position of opening fully of expression throttling flap 4 among Figure 11.In this position of opening fully shown in Figure 11, do not provide low pressure basically by throttling arrangement 1 because by throttling flap 4 do not carry out basically throttling and thus the through flow cross section of through-flow channel 14 basically corresponding to the through flow cross section of throttling flap 4 place's throttling arrangements 1.
The parts of throttling arrangement 1, for example throttling bodies 2 and/or housing 15 are made by metal or plastics usually.
Each embodiment's details can make up mutually, the description of short of opposition.
The advantage that some essence are arranged that interrelates with throttling arrangement 1 according to the present invention and internal-combustion engine 20 according to the present invention taken as a whole.This throttling arrangement 1 also can provide enough low pressure in partial load zone or partially opening in the position of at least one throttling bodies 2.No longer need expensive bypass manifold thus in an advantageous manner or as the low pressure pump electricity of separating device or machinery.
