Vehicular system 116 may also include control system 114.Control system 114, which is shown as receiving, comes from multiple sensors The information of 117 (this document describes its various example), and sent to multiple actuators 181 (this document describes its various example) Control signal.As an example, sensor 117 may include that exhaust sensor 126 (being located in exhaust manifold 148), temperature pass Sensor 191 and pressure sensor 193 (downstream for being located at emission control equipment 170).Such as pressure sensor, temperature sensor, Other sensors of air-fuel ratio sensor and component sensor can be couple to the various positions in Vehicular system 116.Example activates Device 181 may include fuel injector (not shown), various valves, pump and air throttle 162.Control system 114 may include controller 112.Controller 112 receives the signal of the various sensors from Fig. 1, and is based on being connect using the various actuators of Fig. 1 The signal of receipts and the instruction on the memory of controller is stored in adjust power operation.For example, adjustment flow to engine Air inflow in 110 may include the position for adjusting air throttle 162, to increase or decrease by inlet manifold 144 towards engine The air inflow of 110 flowings.In another example, the actuator that the speed of compressor 152 may include to adjust compressor 152 is adjusted (for example, adjustment is fed to the amount of the electric energy of electro-motor 158), to increase or decrease the speed of compressor 152.

Fig. 2 is shown similar to the exemplary turbocharger 202 of the turbocharger 150 shown in Fig. 1 with perspective view.At one In example, the turbocharger 202 (and other turbocharger as described herein and compressor) shown in Fig. 2 can be included in In the engine system of all engine systems 118 as shown in Figure 1.Turbocharger 202 shown in Fig. 2 includes being similar to Fig. 1 The compressor 200 of shown compressor 152, wherein compressor 200 are illustrated in cross-section.Compressor 200 includes described below Housing 203, arrival end 201, flow channel 204 (it is referred to alternatively as central passage herein) and impeller 206.

The flow channel 204 of compressor 200 is configured to make air flow to positioning from the arrival end 201 of compressor 200 The port of export 213 in 206 downstream of impeller.Flow channel 204 can be couple to inlet channel (not shown in Fig. 2), all as shown in Figure 1 And inlet channel 141 described above.Impeller 206 is couple to exhaust driven gas turbine 207 via axis 209.Work as flow of exhaust through exhaust During turbine 207, impeller 206 can be forced to rotate, as described in the turbocharger 150 above with reference to Fig. 1.The rotation of impeller 206 makes Air is flowed from inlet channel and by the arrival end 201 of compressor 200.Flow channel 204 is flowed through in air inlet 211, flows through leaf Take turns 206 and flow in spiral case 215.Then the air inlet compressed can flow out compressor 200 via the port of export 213.

In the illustrated example shown in fig. 2, the housing 203 of compressor 200 is air intake duct housing case.In other words, housing 203 Including around the neighboring of flow channel 204 and setting (for example, formation) in the outer surface 241 of flow channel 204 and housing Resonance chamber 208 between 203 interior surface 242.The outer surface 241 of flow channel 204 and the interior surface of housing 203 242 couple via multiple pillars 210, the pillar 210 on the direction of the central axis 205 of flow channel 204 from interior Portion surface 242 extends to outer surface 241.In example as described herein, the central axis of flow channel is also housing and compression The central axis of machine, and can be by such as referred to herein as.

(for example, when air inlet is flow in arrival end 201 and flows through flow channel 204 during the operation of compressor 200 When), the flowing of the rotation of impeller 206 and the air inlet for passing through compressor 200 can cause noise.Including resonance chamber 208 to subtract Few noisiness produced by compressor 200.For example, when inlet air flow crosses flow channel 204, can be produced in flow channel 204 Acoustic resonance.Flow channel 204 is surrounded by using resonance chamber 208, air can be flowed via passing away 214 from flow channel 204 Move in resonance chamber 208, so as to reduce the amount of resonance in flow channel 204.In other words, passing away 214 will flow logical Road 204 is coupled with 208 fluid of resonance chamber.

However, although resonance chamber 208 reduces the amount of the sound produced by compressor 200, in resonance chamber 208 Noise (for example, acoustic resonance) can also be produced.In order to reduce the amount of the noise produced by resonance chamber 208,212 row of being couple to of hole Go out the flow channel 204 of 214 upstream of passage.Each hole 212 is relative to the logical in flowing in the radial direction of central axis 205 Road extends between 204 resonant cavity room 208, and each hole 212 couples flow channel 204 and 208 fluid of resonance chamber. In one example, resonance chamber 208 can be flow to via passing away 214 by flowing through a part for the air of flow channel 204 In.Then the air flowing in resonance chamber 208 can flow back into flow channel 204 via one or more of hole 212 In.By making air be flow to from resonance chamber 208 in flow channel 204, can reduce air pressure in resonance chamber 208 and The noise produced by resonance chamber 208.Air is set to be flow to from flow channel 204 in resonance chamber 208 via passing away 214 The noisiness produced by compressor 200 can be reduced by the first amount, and make air from resonance via one or more of hole 212 Chamber 208 flow back into the second amount of noise decrease that will can be produced in flow channel 204 by compressor 200.

Fig. 2 to Figure 17 shows the various embodiments of the part of compressor or compressor, wherein each embodiment is including multiple Hole, it is configured to permit the fluid communication between the resonance chamber of flow channel and flow channel.In some examples In, compressor may also include the flowing interference characteristic part being positioned in flow channel.In one example, interference characteristic part is flowed May include step, wherein step relative to the angle of central axis between 10 degree and 170 degree.In other examples, step can It can be formed with different configurations and by multiple surfaces.The example of step, flowing interference characteristic part and hole is described below. In alternative embodiment, the compressor shown in Fig. 2 to Figure 17 can not include flowing interference characteristic part, and alternately include Relatively straight flow channel, its mesopore are arranged between flow channel resonant cavity room.

Fig. 3 show with shown in the compressor 152 or Fig. 2 shown in Fig. 1 and compressor 200 described above is similar shows The cross-sectional view of example compressor 300.Compressor 300 includes the housing 322 with arrival end 301 and the port of export 331.Housing 322 Interior flow channel 304 is configured to air inlet 332 being passed to the port of export 331 from arrival end 301 into becoming a mandarin, and can have Substantially continuous inner surface 328 (it is referred to alternatively as interior surface herein).The central axis 330 of flow channel 304 is shown, its Middle central axis 330 extends through the center of flow channel 304.Compressor wheels 306 are located in housing 322 and including at least one A primary blades 334.Compressor wheels 306 are couple to axis 336 and are configured to rotate to compress air inlet in housing 322.Housing 322 may include to be configured to the successional flowing interference characteristic part for disturbing inner surface 328.In the example depicted in fig. 3, flow Interference characteristic part 316 is located at the leading edge 326 of at least one primary blades 334.In other words, it is opposite to flow interference characteristic part 316 It is axial in line in central axis 330 and leading edge 326.

The cross section of flow channel 304 can be almost circular, and it can be step to flow interference characteristic part 316 318, the diameter of wherein flow channel 304 reduces (for example, being reduced to Second bobbin diameter 329 from first diameter 327) suddenly.In Fig. 3 In shown example, step 318 is a part for the inner surface 328 upwardly extended in the side towards central axis 330.Step 318 enlarged view is shown and is described below by Fig. 4., can by the way that flowing interference characteristic part 316 is formed as step 318 Reduce the cross-sectional area of flow channel 304.For example, when flow channel 304 has cylinder form as shown in Figure 3 (for example, circle Shape cross section) when, step 318 reduces the flow diameter of flow channel 304, this can reduce axial entrance stream and can also or substitute The surge margin (for example, reducing the possibility of the compressor surge during compressor 300 operates) of ground increase compressor, and subtract Utter long and high-pitched sounds less (for example, reducing the amount of the noise produced by compressor 300).

The housing 322 of compressor 300 be with shown in Fig. 2 and air intake duct outer cover that housing 203 described above is similar Housing.Compressor 300 includes being formed by housing 322 and around the resonance chamber 308 of flow channel 304.In other words, such as with Described in resonance chamber 208 shown in upper reference chart 2, the resonance chamber 308 shown in Fig. 3 is formed in the outer surface of flow channel 304 Between 341 and the interior surface 340 of housing 322.By this way, resonance chamber is circumferentially about (for example, in its whole circumference Surrounding surrounds) flow channel 304.Outer surface 341 is couple to interior surface similar to the pillar 342 of the pillar 210 shown in Fig. 2 340.Resonance chamber 308 is via passing away 314, recirculation line 302 and multiple holes 312 and 304 fluid coupling of flow channel Connect.In one example, passing away 314 and recirculation line 302 are the rings formed by the inner surface 328 of flow channel 304 Shape passage, and be arranged between 304 resonant cavity room 308 of flow channel (for example, in the radial direction relative to central axis 330 Extend on direction between the inner surface 328 of flow channel 304 and outer surface 341), so as to by flow channel 304 and resonator Room 308 fluid coupling.In other words, passing away 314 and recirculation line 302 are formed by inner surface 328 and led to along flowing The inner rim extension in road 304.Passing away 314 is positioned at recirculation line 302 with respect to the air stream of flow channel 304 Downstream.In one example, passing away 314 is positioned at the downstream of the leading edge 326 of at least one primary blades 334, and again Circulation canal 302 is positioned at the upstream of leading edge 326.Passing away 314 is positioned such that when compressor wheels 306 rotate, from A part for the air that at least one primary blades 334 flow can flow through passing away 314 and flow in resonance chamber 308. Air is then can flow through resonance chamber 308 and returns to flow channel 304 via recirculation line 302 and/or hole 312, Wherein due to the size that hole 312 reduces relative to recirculation line 302, flowed via recirculation line 302 from resonance chamber 308 The air capacity for moving flow channel 304 is more than the air capacity for flowing to flow channel 304 from resonance chamber 308 via hole 312, As described below.

Compare with passing away 314 and recirculation line 302, hole 312 is not circular passage.Alternatively, at one In example, each hole 312 can relative to central axis 330 in the radial direction in 304 resonant cavity room 308 of flow channel Between extend, so as to which flow channel 304 and 308 fluid of resonance chamber are coupled.Lead to however, hole 312 is not formed around flowing The annular opening of the inner rim in road 304.Alternatively, each hole 312 can have oval or circular cross section, wherein each Hole 312 is positioned away from each other holes 312 so that each hole 312 is between 304 resonant cavity room 308 of flow channel Form cylindrical channel.In one example, each hole 312 can be in flowing relative to central axis 330 in the radial direction Extension between dynamic 304 resonant cavity room 308 of passage (for example, as shown in figure 18).In another example, each hole 312 can Extend on the angled direction relative to central axis 330 between 304 resonant cavity room 308 of flow channel (for example, such as Shown in Figure 19).For example, compressor 300 includes three different holes 312 of the arrangement similar from the hole 212 shown in Fig. 2, Two in its mesopore 312 are visible in the cross-sectional view shown in Fig. 3.Inner surface of each hole 312 from flow channel 304 328 extend to the outer surface 341 of flow channel 304.By this way, fluid (such as air) can be via every in hole 312 It is a to be flowed between 304 resonant cavity room 308 of flow channel so that flow channel 304 is via hole 312 and resonance chamber 308 It is in fluid communication.In addition, fluid can be via both passing away 314 and recirculation line 302 in 304 resonant cavity room of flow channel Flowed between 308.However, although flow channel 304 is in fluid communication via recirculation line 302 and resonance chamber 308, but pass through The air capacity being flow to by recirculation line 302 in flow channel 304 far smaller than flow to flow channel via arrival end 301 Air capacity in 304.In addition, although in addition flow channel 304 is in fluid communication via hole 312 and resonance chamber 308, but pass through The air capacity being flow to by hole 312 in flow channel 304 is less than to be flow in flow channel 304 via recirculation line 302 Air capacity.By this way, hole 312 can reduce the air pressure in resonance chamber 308.

In the example by the fluid stream of flow channel 304, air can enter compressor 300 arrival end 301 and Flowed by flow channel 304 towards compressor wheels 306.When the leading edge 326 of air towards at least one primary blades 334 flows When, a part for air can abut against flowing interference characteristic part 316 (for example, abutting against step 318) flowing, pass through so as to disturb The flow path of the air of flow channel 304.The air for passing through flow channel 304 by using the flowing interference of interference characteristic part 316 Flow path, the damping of the resonant frequency of flow channel 304 can be increased, so as to reduce the noise produced by compressor 300 Amplitude.Under some flow conditions, the entrance that the air stream from least one primary blades 334 can abut against air inlet 332 is flowed back to Stream.Flowing interference characteristic part 316 can increase the expansion of the return air into flow channel 304, so as to by return air with into Gas 332 is mixed into becoming a mandarin.

When air flows up through the leading edge 326 of at least one primary blades 334 in the side of the port of export 331, one of air Dividing can be flow in resonance chamber 308 by passing away 314.The sky in resonance chamber 308 is flow to via passing away 314 Gas can be recycled back into flow channel 304 via recirculation line 302.By making the part of air from flow channel 304 It flow in resonance chamber 308, the noisiness produced by the blade passing frequency of compressor wheels 306 can be reduced.However, when sky When gas flows through resonance chamber 308, the indoor air pressure of resonator can cause undesirable noise.In order to reduce resonance chamber The flow path for the air that air pressure amount and interference in 308 pass through resonance chamber 308, hole 312 are included to provide From resonance chamber 308 to the other inlet air flow path of flow channel 304.By this way, the sky of resonance chamber 308 is flowed through The Part I of gas can be flowed out resonance chamber 308 by recirculation line 302 and be flow back into flow channel 304, and air Part II (wherein Part II is the amount less than Part I) can by one or more of hole 312 flow out it is humorous Shake chamber 308, so as to reduce the amount of the air pressure in resonance chamber 308.Due to the positions and dimensions of hole 312, so by The amplitude for the noise that resonance chamber 308 produces reduces.
