Description

field of technology

[0001] The present description generally concerns exhaust systems with an exhaust component that has multiple functionalities. General state of the art

[0002] Vehicles with internal combustion engines include exhaust systems that capture gases from the combustion engine and ultimately expel them into the surrounding environment. Some exhaust systems incorporate exhaust ports that allow exhaust gases to be released into the environment. Some exhaust ports are positioned in relatively exposed locations on the vehicle. Brief description

[0003] The inventors recognized a need to increase the durability of exhaust tips and to expand the functionality of the exhaust pipe trims or areas of the vehicle surrounding them. In particular, the inventors also recognized that customers may desire the use of accessories (e.g., off-road accessories) such as towing components, brackets, and jack points. The durability of an exhaust tip can be especially desirable when the vehicle is driven in off-road environments.

[0004] In one example, the desirable properties described above can be achieved, at least partially, by an exhaust component mounted in a vehicle chassis. In this example, the exhaust component includes a hook-shaped section configured as a tow hook and / or jack point. Within the exhaust component, the hook-shaped section is positioned adjacent to an exhaust outlet and does not extend directly over the outlet. This allows the exhaust component to perform multiple functions, such as protecting the exhaust outlet, acting as a tow point, and functioning as a jack point.

[0005] As an example, the exhaust component may also include an accessory bracket for mounting accessories, such as a bar. This further enhances the functionality of the exhaust component, thereby increasing its appeal to customers. It is understood that the foregoing summary is provided to introduce, in simplified form, a selection of concepts that are described in greater detail in the detailed description. It is not intended to identify important or defining features of the claimed subject matter, the scope of which is defined solely by the claims that follow the detailed description. Furthermore, the claimed subject matter is not limited to implementations that address any of the disadvantages mentioned above or in any part of this disclosure.

[0006] The following description concerns systems with an exhaust assembly that includes an exhaust component within an exhaust assembly of an exhaust system. Fig. Figure 1 shows an internal combustion engine system with an exhaust system. Fig. Figure 2 shows an example of a vehicle system with a chassis. Fig. Figure 3 shows an example of an exhaust component positioned adjacent to the rear of a vehicle chassis. Fig. Figure 4 shows another example of an exhaust component located on a lateral side of a vehicle. Fig. Figures 5-6 show various examples of spiral devices for cooling exhaust pipes.

[0007] With reference to Fig. 1 is an internal combustion engine 10 comprising a plurality of cylinders, one of which is in Fig. Figure 1 shows that the internal combustion engine is controlled by an electronic combustion engine control unit 12. In the illustrated example, the internal combustion engine 10 is contained within a vehicle 13.

[0008] The internal combustion engine 10 consists of a cylinder head 35 and a cylinder block 33, which include a combustion chamber 30 and cylinder walls 32. A piston 36 is positioned within it and moves back and forth via a connection to a crankshaft 40. A flywheel 97 and a ring gear 99 are coupled to the crankshaft 40. A starter 96 (e.g., a low-voltage electric motor (operated at less than 30 volts)) includes a pinion shaft 98 and a pinion 95. The pinion shaft 98 can selectively advance the pinion 95 to engage the ring gear 99. The starter 96 can be mounted directly on the front or rear of the internal combustion engine. In some examples, the starter 96 can selectively supply torque to the crankshaft 40 via a chain or other suitable component. In one example, the starter motor 96 is in a basic state when it is not engaged with the internal combustion engine crankshaft.According to the illustration, the combustion chamber 30 is connected to an intake manifold 44 and an exhaust manifold 48 via a corresponding intake valve 52 and exhaust valve 54. Each intake and exhaust valve can be operated by an intake cam 51 and an exhaust cam 53. The position of the intake cam 51 can be determined by an intake cam sensor 55. The position of the exhaust cam 53 can be determined by an exhaust cam sensor 57. The intake valve 52 can be selectively opened and closed by a valve actuation device 59. The exhaust valve 54 can be selectively opened and closed by a valve actuation device 58. The valve actuation devices 58 and 59 can be hydraulic and / or electromechanical devices.

[0009] A fuel injection device 66 is positioned, as shown, to inject fuel directly into the cylinder 34, a process known to those skilled in the art as direct injection. The fuel injection device 66 delivers liquid fuel proportionally to the pulse width from the controller 12. The fuel is supplied to the fuel injection device 66 by a fuel system (not shown) comprising a fuel tank, a fuel pump, and a fuel distributor (not shown). For example, a two-stage high-pressure fuel system can be used to generate higher fuel pressures.

[0010] Additionally, the intake manifold 44 is connected to an engine air intake 42, as shown in the illustration. An optional electronic throttle 62 sets the position of a throttle valve 64 to control the airflow from the engine air intake 42 to the intake manifold 44. In some examples, the throttle 62 and the throttle valve 64 can be positioned between the intake valve 52 and the intake manifold 44 such that the throttle 62 acts as an intake port throttle. An air filter 43 cleans the air entering the engine air intake 42. A distributorless ignition system 88 provides a spark to the combustion chamber 30 via a spark plug 92 in response to the control unit 12.

[0011] The internal combustion engine 10 also includes an exhaust system 63 that receives exhaust gas from the combustion chamber 30. According to the illustration, a wideband lambda sensor (universal exhaust gas oxygen sensor - UEGO sensor) 126 is coupled to the exhaust manifold 48 upstream of a catalytic converter 70 in the exhaust system 63. Alternatively, the UEGO sensor 126 can be replaced by a binary lambda sensor.

[0012] The catalytic converter 70 can, in one example, contain multiple catalyst honeycomb bodies. In another example, multiple emission control devices, each with multiple honeycomb bodies, can be used. The catalytic converter 70 can, in one example, be a three-way catalyst. The temperature of the catalytic converter 70 (e.g., of the catalyst) can be monitored via a temperature sensor 72.

[0013] Control 12 is in Fig. Figure 1 is depicted as a conventional microcomputer comprising: a microprocessor unit 102, input / output ports 104, read-only memory 106 (e.g., persistent memory), random-access memory 108, keep-alive memory 110, and a conventional data bus. According to the illustration, the controller 12 receives various signals from sensors coupled to the internal combustion engine 10, which, in addition to the signals discussed above, include: engine coolant temperature (ECT) from a temperature sensor 112 coupled to a cooling sleeve 114; a position sensor 134 coupled to a driver-activated pedal 130 to detect a force exerted by a human foot 132;a position sensor 154, coupled to a brake caliper control pedal 150, for detecting a force exerted by a foot 152; a measurement of the combustion engine manifold pressure (MAP) from a pressure sensor 122, coupled to the intake manifold 44; a combustion engine position sensor from a position sensor 118, which detects the position of the crankshaft 40; a measurement of the mass of air entering the combustion engine from a sensor 120; and a measurement of the throttle position from a sensor 68. The air pressure can also be detected for processing by the controller 12. A position sensor 118 can generate a predetermined number of evenly spaced pulses with each revolution of the crankshaft, from which the combustion engine speed (rpm) can be determined.

[0014] During operation, each cylinder within the internal combustion engine 10 typically goes through a four-stroke cycle: The cycle includes the intake stroke, the compression stroke, the power stroke, and the exhaust stroke. During the intake stroke, the exhaust valve 54 generally closes and the intake valve 52 opens. Air is drawn into the combustion chamber 30 via the intake manifold 44, and the piston 36 moves toward the bottom of the cylinder to increase the volume within the combustion chamber 30. The position at which the piston 36 is near the bottom of the cylinder and at the end of its stroke (e.g., when the combustion chamber 30 has reached its maximum volume) is typically referred to by someone skilled in the art as bottom dead center (BDC).

[0015] During the compression stroke, the intake valve 52 and the exhaust valve 54 are closed. The piston 36 moves towards the cylinder head to compress the air within the combustion chamber 30. The point at which the piston 36 is closest to the cylinder head at the end of its stroke (e.g., when the combustion chamber 30 has its smallest volume) is commonly referred to by those skilled in the art as top dead center (TDC). In a process referred to herein as injection, fuel is introduced into the combustion chamber. In a process referred to below as ignition, the injected fuel is ignited by known ignition means, such as the spark plug 92, resulting in combustion.

[0016] During the power stroke, the expanding gases push the piston 36 back to bottom dead center (BDC). The crankshaft 40 converts the piston movement into a torque of the crankshaft. Finally, during the exhaust stroke, the exhaust valve 54 opens to release the burnt air-fuel mixture to the exhaust manifold 48, and the piston returns to top dead center (TDC). It should be noted that the above is shown only as an example and that the timing of the opening and / or closing of the intake and exhaust valves can vary, for example, to provide positive or negative valve overlap, late closing of the intake valve, or various other examples.

[0017] Vehicle 13 can be a hybrid vehicle in one example. In such an example, vehicle 13 includes an electric motor, a traction battery, and the like. In the hybrid vehicle example, the traction motor and the combustion engine can have a variety of suitable architectures.

[0018] Fig. Figure 2 shows an example of a vehicle 200 with a chassis 202. It is understood that in various embodiments at least some of the components in the vehicle 13, which is shown in Fig. Figure 1 shows that vehicle 200 may be included, which is in Fig. 2 is shown, and vice versa.

[0019] The chassis 202 can include a frame 204, axles 206 with drive wheels 208, and the like. The chassis 202 includes a front 210, a rear 212, and lateral sides 214. It is understood that in various examples, an exhaust component may be located adjacent to or coupled to the chassis. More precisely, in one example, the exhaust component may be coupled to the rear 212 of the chassis 202, or in another example, it may be located adjacent to or coupled to one of the lateral sides of the chassis. Exemplary exhaust components are shown in Fig. Figures 3-4 are shown and discussed in more detail in this document. An axis system is shown in Figures 3-4. Fig. 2 as well as Fig. Figures 3-6 are provided for reference. In one example, the z-axis can be a vertical axis (e.g., parallel to a gravitational axis), the x-axis can be a longitudinal axis (e.g., a horizontal axis), and / or the y-axis can be a lateral axis. In other examples, however, the axes may have different orientations.

[0020] Fig. Figure 3 shows an example of an exhaust assembly 300 with an exhaust component 302 coupled to exhaust pipe baffles 304 and 306. Specifically, the illustrated example includes two exhaust pipe baffles. However, it is understood that the exhaust assembly can include a single exhaust pipe baffle or more than two. In the illustrated example, the exhaust component 302 is positioned at the rear 308 of a vehicle 310. This allows easy access to the exhaust component. It is understood that the exhaust assembly 300 can be included in any of the exhaust systems or combinations of exhaust systems described above.

[0021] The exhaust component 302 includes a hook-shaped section 312. The hook-shaped section 312 allows the exhaust component to interface with a tow hook and a jack. In this way, the functionality of the exhaust assembly 300 is increased, thereby enhancing its appeal to customers.

[0022] In the illustrated example, the hook-shaped section 312 includes a central subsection 314 and side sections 316 and 318. More precisely, the exhaust component 302 can be symmetrical about an axis 320. However, asymmetrical designs for exhaust components have been considered.

[0023] In the illustrated example, an accessory bracket 322 is arranged in the central subsection 314. The accessory bracket 322 is configured to accommodate a pole 324 (e.g., a flagpole). In one example, the central axis of the accessory bracket 322 can be arranged vertically to allow the pole to be mounted vertically.

[0024] The hook-shaped section 312 is positioned at least partially vertically below outlets 326 and 328 of the exhaust pipe baffles 304 and 306. Furthermore, in the illustrated example, the hook-shaped section 312 extends outwards from the exhaust pipe baffles 304 and 306 in a reverse direction 313. This reduces the risk of blockage in the exhaust pipes, thereby improving the performance of the exhaust system.

[0025] The exhaust component 302 can be constructed from one or more metallic materials, polymer materials, combinations thereof, and the like. In the illustrated example, the exhaust component 302 and the exhaust pipe baffles 304 and 306 are positioned vertically below a bumper 330. However, in other examples, the exhaust component and the exhaust baffles can be arranged in other suitable locations.

[0026] Exhaust component 302 includes exhaust port interfaces 332 and 334, which surround exhaust port ports 304 and 306. In one example, the exhaust port interfaces 332 and 334 may not directly contact the exhaust port ports 304 and 306. More precisely, a gap may be formed between the exhaust port interfaces 332 and 334 and the exhaust port ports 304 and 306. In other examples, however, the exhaust port interfaces may be directly connected to the exhaust port ports by welding, adhesives, combinations thereof, and the like.

[0027] In the illustrated example, the hook-shaped section 312 includes an upper surface 336, a lower surface 338, and a vertical surface 340 extending between them. However, other contours for hook-shaped sections have also been considered. For example, the hook-shaped section may include one or more curved surfaces. A gap 342 may be provided between the hook-shaped section 312 and the body of the exhaust component 302 to allow a tow hook to interface with it.

[0028] The exhaust component 302 can be integrated into the bumper 330. In other examples, the exhaust component 302 can be attached to a chassis of the vehicle (e.g., the chassis 202, which is in Fig. (as shown in Figure 2). Alternatively, the exhaust component 302 can be positioned adjacent to one of the chassis frame rails. Furthermore, in other examples, the exhaust component can be formed integrally with a section of the chassis.

[0029] Fig. Figure 4 shows another example of an exhaust assembly 400 with an exhaust component 401, which in the illustrated example is arranged on a lateral side 402 of a vehicle 404. However, the exhaust component 401 can be arranged in other suitable positions, such as at the rear of the vehicle, as discussed above.

[0030] The exhaust component 401 circumferentially surrounds the exhaust pipe baffles 406 and 408, which are included in the exhaust assembly 400 in the illustrated example. Specifically, a gap 409 is formed between the exhaust component 401 and the exhaust pipe baffles 406 and 408. More precisely, the gap 409 is formed between a lower surface 440, side surfaces 442 and 444, and an upper surface 446 of the exhaust component 401 and the outer surfaces 448 of the exhaust pipe baffles 406 and 408. In other examples, however, the exhaust component 401 may be coupled to the exhaust pipe baffles. Similar to the other exhaust components described in this document, the exhaust component 401 may be attached to a chassis of the vehicle or arranged adjacent to a section of the chassis.

[0031] The exhaust component 401 again includes a hook-shaped section 410. In the example shown in Fig. As illustrated in Figure 4, the hook-shaped section 410 extends over the component in a vertical and inward-facing direction. In alternative examples, however, the hook may have other orientations. Furthermore, the hook-shaped section 410 may have a flat outer surface 412 to reduce the likelihood of the hook interacting with objects in the surrounding environment. Additionally, the hook-shaped section 410 may be located on a rear face 414 of the exhaust component 401.

[0032] In the illustrated example, the exhaust component 401 also includes an accessory bracket 416. The accessory bracket 416 is configured to receive a rod 418 and / or other suitable accessory. In the illustrated example, the hook-shaped section 410 is positioned vertically below the exhaust pipe baffles 406 and 408, and the accessory bracket 416 is positioned vertically above the exhaust pipe baffles. This arrangement facilitates access to the hook and the accessory bracket. The accessory bracket 416 may include a flat upper surface 419 and a flat lower surface 420.

[0033] The exhaust component 401 includes a rock slider 422, which in the illustrated example is positioned on a bottom surface 424 of the component. In this way, it is less likely that stone chips or other types of environmental object interaction will wear down the exhaust pipe baffles 406 and 408. The rock slider 422 can include a flat surface 425 that is angled inwards with respect to a vertical axis. Fig. Figure 5 shows an example of a spiral device 500 that can be coupled to an exhaust pipe, such as any of the exhaust pipes or combinations of exhaust pipes described above. In the example shown in Fig. As illustrated in Figure 5, the spiral device 500 comprises spiral walls 502 arranged around a central axis 504. More precisely, the spiral walls 502 can include opposing circumferential surfaces 506 and 508 that guide fluid in channels 510 formed between the spiral walls. An exhaust pipe 512 can extend through the spiral device 500. More precisely, the spiral device 500 can be coupled to an outer surface of the exhaust pipe 512. In such an example, the spiral walls 502 can terminate at the outer surface of the exhaust pipe. The spiral walls 502 guide air around the exhaust pipe 512 to dissipate heat from the exhaust gas flowing through it without increasing the exhaust back pressure.

[0034] Fig. Figure 6 shows another example of a spiral diffuser device 600, which may be at least partially enclosed within an exhaust pipe, such as any of the exhaust pipes or combinations of exhaust pipes described above. The spiral device 600, which is in Fig. Figure 6 shows a front section 602, a rear section 604, and spiral extensions 606 extending between the front and rear sections. An exhaust pipe 608 can extend from the front section 602 to the rear section 604 through the spiral device 600. The spiral extensions 606 direct an airflow around the exhaust pipe 608 to dissipate heat from the exhaust gas flowing through it without increasing the exhaust back pressure.

[0035] The spiral devices described in this document can be constructed using various methods, including additive manufacturing, casting, and / or machining. Additive manufacturing of these spiral devices allows for the dissipation of a greater amount of heat from the exhaust gas with less back pressure.

[0036] Fig. Figures 3-6 are shown approximately to scale.

[0037] Fig.Figures 1-6 show exemplary configurations with a relative positioning of the various components. If it is shown that such elements are directly touching or directly coupled, such elements may be described as directly touching or directly coupled, at least in one example, unless otherwise noted. Likewise, elements shown as connected or adjacent to each other may be described as connected or adjacent, at least in one example. As one example, components that are in surface-dividing contact with each other may be described as being in surface-dividing contact. As another example, elements that are positioned separately from each other, with only a gap between them and no other components, may be described as such in at least one example.As another example, elements shown above / below each other, on opposite sides of each other, or to the left / right of each other can be described in this way relative to one another. Furthermore, as shown in the figures, a topmost element or the highest point of an element can be referred to as the "top" of the component in at least one example, and a bottommost element or the lowest point of the element can be referred to as the "bottom" of the component. In the sense used here, top / bottom, upper / lower, and above / below can refer to a vertical axis of the figures and be used to describe the arrangement of elements of the figures in relation to one another. Thus, in one example, elements shown above other elements are positioned vertically above the other elements.As another example, the shapes of elements depicted within the figures can be described as having these shapes (such as circular, straight, planar, curved, rounded, beveled, angled, or the like). Furthermore, elements shown intersecting each other can, in at least one example, be described as intersecting elements or as intersecting each other. Even further, an element shown within another element or shown outside another element can, in one example, be described as such.

[0038] In one embodiment, an exhaust component is provided comprising: a hook-shaped section configured as a tow hook and / or jack interface; wherein the hook-shaped section is positioned adjacent to an exhaust pipe baffle; and wherein the hook-shaped section does not extend directly over the exhaust pipe baffle.

In yet another example, the exhaust component may further include a spiral device coupled to the exhaust pipe baffle and configured to dissipate heat from an exhaust flow through the exhaust pipe. In still another example, the spiral device may be additively manufactured.
