[0058] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 5 The following describes an engine 100 according to an embodiment of the first aspect of the present invention. In the following description, the engine 100 is used in a vehicle (not shown) as an example for detailed description.

[0059] like Figure 1 As shown, the engine 100 according to the first embodiment of the present invention comprises a main body 1, an exhaust manifold 2 and a plurality of heat insulating members 3. In the description of the present invention, "plurality" means two or more.

[0060] Specifically, a heat loss component 11 is connected to the main body 1, the exhaust manifold 2 is arranged above the main body 1, at least part of the exhaust manifold 2 is opposite to the heat loss component 11, and at least one thermal insulation member 3 is arranged between the exhaust manifold 2 and the heat loss component 11.

[0061] For example, in Figure 1 and Figure 2 In the example, the four inlets of the exhaust manifold 2 are connected to the main body 1, and the peripheral side and lower side of the exhaust manifold 2 are opposite to the heat loss component 11. Among them, when the power generation assembly 200 of the vehicle is working, the exhaust gas flows along the exhaust manifold 2, and the inner wall temperature of the exhaust manifold 2 can reach above 1000°C. The components around the exhaust manifold 2 are faced with a poor thermal environment, and the components are easily damaged in the thermal environment. In this application, the above-mentioned easily damaged components can be referred to as heat loss components 11. With such a configuration, the heat insulation member 3 can block the heat radiation received by the heat loss component 11 in the thermal environment, reduce the amount of heat received by the heat loss component 11, and avoid the risk of heat damage to the heat loss component 11, so that the heat loss component 11 can be used normally for a long time, thereby extending the service life of the engine 100. In addition, the position of the heat insulation member 3 is reasonably set, and the heat insulation member 3 can shield and protect the heat loss component 11, thereby improving the thermal insulation effect, thereby further insulating protection, and further avoiding damage to the heat loss component 11.

[0062] In the engine 100 of the present invention, the thermal insulator 3 blocks heat radiation, reducing the amount of heat received by the heat-damaging component 11 and preventing damage to the heat-damaging component 11. This allows the heat-damaging component 11 to function properly for extended periods of time, extending the service life of the engine 100. Furthermore, the thermal insulator 3 is strategically positioned, enhancing the insulation effect and further preventing damage to the heat-damaging component 11.

[0063] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The heat loss component 11 includes a cooling group 111, and the cooling group 111 includes a cooling pipe 1111. The cooling pipe 1111 is located above the main body 1 and is spaced apart from the exhaust manifold 2. The plurality of heat insulating members 3 include a first heat insulating member 31, which is provided between the exhaust manifold 2 and the cooling pipe 1111. The shape of the first heat insulating member 31 is adapted to the outer peripheral surface shape of the cooling pipe 1111. For example, in Figure 2 and Figure 3 In the example, the cooling pipe 1111 and the exhaust manifold 2 are arranged in a first direction (eg Figure 2 The exhaust manifolds 2 are arranged in a spaced manner along the second direction (as shown in the left and right directions). Figure 2 The cooling pipe 1111 extends in the front-to-rear direction as shown, and is located between the exhaust manifold 2 and the main body 1.

[0064] With such an arrangement, the first thermal insulation member 31 can insulate the cooling pipe 1111, preventing the heat from the exhaust manifold 2 from causing heat loss to the cooling pipe 1111, thereby extending the service life of the cooling pipe 1111. In addition, the shape of the first thermal insulation member 31 is compatible with the shape of the outer peripheral surface of the cooling pipe 1111, which facilitates the compact arrangement of the first thermal insulation member 31 and the cooling pipe 1111, thereby reducing the space occupied by the first thermal insulation member 31 and facilitating the arrangement of the first thermal insulation member 31. Moreover, the shielding effect of the first thermal insulation member 31 on the cooling pipe 1111 is also improved, effectively shielding the heat source and the heat damage risk area, improving the thermal insulation effect, thereby improving the protection of the cooling group 111 and preventing the cooling group 111 from being damaged. In addition, the first thermal insulation member 31 has a compact and beautiful structure, which is easy to design and install. The cooling group 111 further includes an oil cooler 1112 and a thermostat 1113. The cooling pipe 1111 is located between the oil cooler 1112 and the thermostat 1113. The oil cooler 1112 is connected to the front end of the cooling pipe 1111, and the thermostat 1113 is connected to the rear end of the cooling pipe 1111. Thus, the cooling pipe 1111, the oil cooler 1112, and the thermostat 1113 cooperate with each other to cool the engine 100. It should be noted that if the minimum spacing between the cooling group 111 and the exhaust manifold 2 is less than 10 mm, for example, if the minimum spacing is 5 mm, there is a thermal risk. The cooling water temperature in the cooling pipe 1111 may be too high, leading to surface material failure.

[0065] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 The first heat insulating member 31 has a flange 311 on one side away from the main body 1, and the free end of the flange 311 is bent and extended in a direction away from the cooling pipe 1111. For example, Figure 2 and Figure 3 In the example, the upper end (i.e., the free end) of the flange 311 bends and extends upward. In this way, the flange 311 can shield components such as the oil cooler 1112 and the thermostat 1113, reducing the heat loss caused by the heat of the exhaust manifold 2 to the cooling pipe 1111, the oil cooler 1112, and the thermostat 1113, thereby extending the service life of the cooling group 111. In addition, the convective air can also flow along the bottom or top of the first thermal insulation member 31 to avoid the formation of a flow dead zone on the envelope surface, thereby facilitating the smooth discharge of heat with the air and reducing the heat inside the engine 100. Figure 1 , the direction indicated by arrow A is the direction of air flow.

[0066] According to some embodiments of the present invention, the first thermal insulation member 31 is connected to the main body 1. This arrangement enhances the connection stability of the first thermal insulation member 31, prevents shaking of the first thermal insulation member 31, and thus reduces vibration of the first thermal insulation member 31. It should be noted that the first thermal insulation member 31 and the main body 1 can be connected directly or indirectly via other components. Multiple connection points are provided between the first thermal insulation member 31 and the main body 1, further enhancing the stability of the first thermal insulation member 31.

[0067] According to some embodiments of the present invention, referring to Figure 1 and Figure 4 The heat loss component 11 includes a supercharger 112, which is connected to the outlet of the exhaust manifold 2. The supercharger 112 is located along the first direction (such as Figure 1 The plurality of heat insulating members 3 include a second heat insulating member 32, which covers the top surface of the supercharger 112 and the side surface of the supercharger 112 facing the exhaust manifold 2. For example, Figure 1 and Figure 4 In the example shown, the inlet of supercharger 112 is connected to the outlet of exhaust manifold 2, and supercharger 112 is located on the left side of main body 1. This arrangement allows second thermal insulator 32 to insulate supercharger 112, preventing heat damage to supercharger 112 from exhaust manifold 2, thereby extending the service life of supercharger 112. Furthermore, second thermal insulator 32 shields and protects supercharger 112, providing significant insulation and preventing damage.

[0068] According to some embodiments of the present invention, referring to Figure 4 , the shape of the second thermal insulation member 32 is adapted to the shape of the outer peripheral surface of the supercharger 112. As a result, the second thermal insulation member 32 and the supercharger 112 can be arranged compactly, thereby reducing the space occupied by the second thermal insulation member 32 and facilitating the arrangement of the second thermal insulation member 32. Moreover, the second thermal insulation member 32 is designed along the volute of the supercharger 112, which can achieve complete shielding of the supercharger 112 components, effectively shielding the heat source and the heat damage risk area, and has a good heat insulation effect, thereby further improving the protection of the supercharger 112 and further avoiding the risk of heat damage to the supercharger 112. In addition, the second thermal insulation member 32 has a compact and beautiful structure and is easy to design and install. Among them, the second thermal insulation member 32 is connected to the supercharger 112, and there are multiple connection points between the second thermal insulation member 32 and the supercharger 112, thereby reducing the vibration of the second thermal insulation member 32.

[0069] According to some embodiments of the present invention, referring to Figure 5 The exhaust manifold 2 includes a first body layer 21 and a second body layer 22 arranged at intervals along the radial direction of the exhaust manifold 2, and the second body layer 22 is arranged on the outer peripheral side of the first body layer 21. Figure 5In the example, the second body layer 22 wraps the first body layer 21. With this arrangement, the exhaust manifold 2 itself can have a heat-insulating effect, that is, it insulates from the heat source, so that the heat insulation effect is obvious, which reduces the heat generated by the exhaust manifold 2 to the surrounding environment and reduces heat damage. In addition, the first body layer 21 and the second body layer 22 are consistent with the configuration of the exhaust manifold 2 itself. While reducing the radiation temperature of the outer surface of the exhaust manifold 2, no additional space and installation are required. The structure is compact and easy to install, thereby improving the installation efficiency of the exhaust manifold 2. Moreover, the arrangement of the first body layer 21 and the second body layer 22 also makes the exhaust manifold 2 have good sound insulation and vibration isolation effects, thereby improving the performance of the exhaust manifold 2.

[0070] Further, refer to Figure 5 , a heat insulation layer 23 is provided between the first body layer 21 and the second body layer 22. For example, Figure 5 In the example, the exhaust manifold 2 has a sandwich-like insulation structure. With this configuration, the insulation layer 23 has a heat-insulating effect, thereby further improving the insulation effect of the exhaust manifold 2 itself, reducing the heat damage caused by the exhaust manifold 2 to the heat-damaging component 11, and thereby increasing the service life of the engine 100. In addition, the insulation layer 23 also further improves the sound insulation and vibration isolation effects, further improving the performance of the exhaust manifold 2. The insulation layer 23 can be a hydrogel member or a glass fiber member, but is not limited thereto. It should be noted that the thickness of the first body layer 21, the second body layer 22, and the insulation layer 23 can be determined according to space and performance requirements.

[0071] According to some embodiments of the present invention, the first body layer 21 and / or the second body layer 22 are metal components. For example, the first body layer 21 and the second body layer 22 may be configured as follows: First, the first body layer 21 is a metal component. Second, the second body layer 22 is a metal component. Third, the first body layer 21 and the second body layer 22 are metal components. This configuration provides excellent mechanical properties for the metal components, thereby improving the structural strength of the first and second body layers 21, 22, preventing deformation of the first and second body layers 21, 22, and extending the service life of the exhaust manifold 2.

[0072] According to some embodiments of the present invention, the outer peripheral surface of the second body layer 22 is coated with a thermal insulation coating (not shown). As a result, the thermal insulation coating further improves the thermal insulation effect of the exhaust manifold 2 itself, that is, further reduces the temperature around the exhaust manifold 2, thereby improving the thermal environment of the heat loss component 11 and reducing the thermal damage to the heat loss component 11. The thermal damage risk is determined by combining the temperature of the exhaust manifold 2, the temperature resistance requirements of the heat loss component 11, and the distance between the two. The thermal damage point is designed with a single thermal insulation member 3 that matches the contour of the heat loss component 11. The thermal insulation member 3 and the heat loss component 11 are contoured and evenly arranged with several connection points. The thermal insulation is stable and efficient, and is conducive to air circulation without forming a flow dead zone that causes heat accumulation.

[0073] According to the second embodiment of the present invention, the power generation assembly 200, Figure 6 and Figure 7 , including the engine 100 according to the above-mentioned first aspect embodiment of the present invention.

[0074] According to the power generation assembly 200 of the present invention, by adopting the above-mentioned engine 100, thermal insulation is performed from multiple angles of heat source and heat transfer process, and the thermal insulation effect is significant, thereby avoiding damage to the heat loss component 11, thereby extending the service life of the power generation assembly 200.

[0075] According to some embodiments of the present invention, referring to Figure 6 and Figure 8 The power generation assembly 200 further includes a motor 201 and a motor heat insulation member 202. The motor 201 is located on the main body 1 of the engine 100 along the first direction (such as Figure 6 The motor 201 is located on one side of the main body 1 and is adjacent to the supercharger 112 of the engine 100. The motor heat insulation member 202 covers at least one side surface of the motor 201 facing the supercharger 112 and one side surface of the motor 201 away from the main body 1.

[0076] For example, in Figure 6 、 Figure 8 and Figure 9In the example, the motor 201 is located on the left side of the main body 1, and the motor 201 is located in front of the supercharger 112. Thus, the motor heat insulation 202 shields the motor 201, which can shield the heat from the supercharger 112 and the exhaust manifold 2, and isolate the heat transfer of the motor 201 close to the heat source. That is, the motor heat insulation 202 can isolate the heat radiation and heat convection of the external heat source of the motor 201, protect the internal components of the motor 201, and avoid heat loss of the motor 201, thereby reducing the failure rate of the motor 201 during operation and increasing the service life of the motor 201. In addition, a portion of the motor heat insulation 202 covers the side surface of the motor 201 away from the main body 1 (that is, the left side surface of the motor 201), preventing the motor 201, which has heated up after working for a certain period of time, from dissipating heat to the adjacent components, which is beneficial to the normal use of the motor 201 and the components adjacent to the motor 201.

[0077] According to some embodiments of the present invention, referring to Figure 10 and Figure 11 The power generation assembly 200 further includes an oil pump 203 connected to the side of the motor 201. The motor heat insulation member 202 has an extension portion 2021, which is located between the motor 201 and the main body 1 and at least blocks the side of the oil pump 203 facing the main body 1.

[0078] For example, in Figure 10 and Figure 11 In the example, the oil supply pump 203 is located on the lower side of the motor 201, and the oil supply pump 203 is connected to the lower side of the motor 201. The extension portion 2021 is located on the right side of the oil supply pump 203, and the extension portion 2021 covers at least the right side of the oil supply pump 203. With this arrangement, the motor thermal insulation component 202 includes the motor 201 and the oil supply pump 203, achieving full wrapping of the heated surface, reducing the temperature of the environment in which the oil supply pump 203 is located, meeting the thermal insulation requirements of the oil supply pump 203, and thus extending the service life of the oil supply pump 203. In addition, the motor thermal insulation component 202 is stamped and formed in a fully wrapped manner to isolate the heat radiation and heat convection of external heat sources, thereby improving the heating condition of the motor 201 and facilitating the normal use of the motor 201 for a long time.

[0079] According to some embodiments of the present invention, referring to Figure 10 The portion of the motor heat insulation member 202 that covers the surface of the motor 201 facing the supercharger 112 is formed into an arc surface. Figure 10In the example, the motor heat insulation member 202 is located between the supercharger 112 and the motor 201 on one side and has an arc surface. This configuration allows the motor heat insulation member 202 to match the shape of the motor 201, effectively saving assembly space and insulation materials. It is easier to integrate while meeting the insulation requirements, making the arrangement more compact, reducing the space occupied by the motor heat insulation member 202, and providing flexible layout. It also increases the insulation area of the motor heat insulation member 202 for the motor 201, thereby improving the protection effect. In addition, it reduces the accumulation of heat on the above-mentioned arc surface and improves eddy currents. Moreover, it has a guiding effect on the surrounding heat.

[0080] Alternatively, as Figure 8 As shown, the end of the supercharger 112 away from the exhaust manifold 2 is connected to a catalyst 207. The curved surface of the motor heat insulator 202 is semi-enclosed around the rear side and bottom of the motor 201, which can insulate the heat from the supercharger 112 and the catalyst 207, further effectively preventing heat damage to the motor 201. The outer surface of the curved surface of the motor heat insulator 202 is smooth, which acts as a guide for heat transfer from the supercharger 112. It should be noted that the distance between the outlet flange of the exhaust manifold 2 and the connection surface between the motor 201 and the engine 100 is less than 10mm. For example, if the distance is 5mm, there is a risk of failure of components at the connection surface between the motor 201 and the engine 100 (such as bolts and seals). The minimum distance between the catalyst 207 and the side of the motor 201 is less than 30mm. For example, if the minimum distance is 22mm, there is a risk of heat damage. The minimum distance between the supercharger 112 and the side of the motor 201 is less than 30mm. For example, if the minimum distance is 25mm, there is a risk of heat damage.

[0081] According to some embodiments of the present invention, referring to Figure 8 and Figure 11 , a plurality of first mounting holes 2022 are formed on the motor thermal insulation 202, and the power generation assembly 200 further includes a fastener 204, and the plurality of fasteners 204 are respectively connected to the motor 201 through the plurality of first mounting holes 2022. Thus, the motor thermal insulation 202 is connected to the motor 201 through the corresponding cooperation of the plurality of fasteners 204 and the plurality of first mounting holes 2022, which improves the use stability of the motor thermal insulation 202 and reduces the vibration of the motor thermal insulation 202, thereby improving the rigidity of the installation of the motor thermal insulation 202 and improving the noise, vibration and harshness (NVH) characteristics, thereby improving the use performance of the motor thermal insulation 202. In addition, the plurality of first mounting holes 2022 do not interfere with other components, and the structure is simple while ensuring the vibration level of the insulation structure. It should be noted that the fastener 204 can be a bolt. The number and arrangement of the first mounting holes 2022 are specifically set according to actual usage.

[0082] According to some embodiments of the present invention, referring to Figure 12The power generation assembly 200 further includes an electric control box 205 and an electric control box heat insulation member 206. The electric control box 205 is located on the main body 1 of the engine 100 along the first direction (eg Figure 12 The electric control box 205 and the supercharger 112 of the engine 100 are respectively connected to the main body 1 along the second direction (as shown in the left and right directions). Figure 12 The electric control box heat insulation member 206 is located between the electric control box 205 and the exhaust manifold 2 of the engine 100. For example, Figure 12 In the example shown, the electrical control box 205 is located on the left side of the main body 1 of the engine 100. The electrical control box 205 is connected to the front end of the main body 1, while the supercharger 112 of the engine 100 is connected to the rear end of the main body 1. This arrangement protects the electrical control box 205 from the effects of heat radiation from the exhaust manifold 2, minimizing damage to the electrical control box 205. This improves the performance of the electrical control box 205 and extends its service life.

[0083] According to some embodiments of the present invention, referring to Figure 13 and Figure 14 The electrical control box insulation 206 includes an insulation section 2061, a first fixing section 2062, and a second fixing section 2063. The insulation section 2061 is in contact with the side of the electrical control box 205 facing the exhaust manifold 2. The first fixing section 2062 is connected to one side of the insulation section 2061 and extends along the thickness of the insulation section 2061. The first fixing section 2062 is connected to the top surface of the electrical control box 205. The second fixing section 2063 is connected to the other side of the insulation section 2061 and extends along the thickness of the insulation section 2061 away from the first fixing section 2062. The second fixing section 2063 is connected to the main body 1.

[0084] For example, in Figure 13 In the example shown in FIG, the right end of the first fixing section 2062 is connected to the upper side of the thermal insulation section 2061, and the left end of the first fixing section 2062 extends away from the thermal insulation section 2061. The left end of the second fixing section 2063 is connected to the lower side of the thermal insulation section 2061, and the right end of the second fixing section 2063 extends away from the thermal insulation section 2061.

[0085] This arrangement ensures that the insulation of the electric control box insulation 206 is insulated, facilitates the connection of the electric control box insulation 206 to the electric control box 205 via the first fixing section 2062, and facilitates the connection of the electric control box insulation 206 to the main body 1 via the second fixing section 2063. This reduces the difficulty of assembling the electric control box insulation 206, improves the installation efficiency of the power generation assembly 200, improves the installation stability of the electric control box insulation 206, and reduces the vibration of the electric control box insulation 206. In addition, the partial wrapping structure ensures the insulation effect according to the requirements of the shape and position of the electric control box 205, reduces the overall layout space, and avoids material waste. Moreover, the electric control box insulation 206 has a simple structure and is easy to process, which improves the production efficiency of the electric control box insulation 206. Among them, the insulation section 2061 can be set as a curved surface, thereby enhancing the structural strength of the electric control box insulation 206 and improving the performance of the electric control box insulation 206. Moreover, the heat exchange area of the surface of the heat insulation section 2061 is increased, which also has a guiding effect, thereby improving the heat insulation effect.

[0086] Further, refer to Figure 13 At least one avoidance hole 2062a is formed on the first fixing section 2062. The avoidance hole 2062a extends in a direction perpendicular to the plane where the heat insulating section 2061 is located, and the side of the avoidance hole 2062a away from the heat insulating section 2061 passes through the edge of the first fixing section 2062. For example, Figure 13 In the example shown, the avoidance hole 2062a extends in the left-right direction, with the right side of the avoidance hole 2062a extending to the upper edge of the thermal insulation section 2061, and the left side of the avoidance hole 2062a extending to the left edge of the first fixing section 2062. The left side of the avoidance hole 2062a also penetrates the left edge of the first fixing section 2062. With this arrangement, the avoidance hole 2062a avoids contact with the bolts on the electric control box 205, thereby facilitating the installation of the electric control box thermal insulation member 206 on the electric control box 205. The arrangement also reduces the distance between the thermal insulation section 2061 of the electric control box thermal insulation member 206 and the electric control box 205, making the arrangement of the electric control box thermal insulation member 206 compact and flexible.

[0087] According to some embodiments of the present invention, referring to Figure 14 The first fixing section 2062 is formed with a plurality of second mounting holes 2062b, and the avoidance holes 2062a are multiple, and the multiple avoidance holes 2062a and the multiple second mounting holes 2062b are arranged along the second direction (such as Figure 14 and / or, a plurality of third mounting holes 2063a are formed on the second fixing section 2063, and the plurality of third mounting holes 2063a are arranged at intervals along the second direction.

[0088] For example, the settings of the first fixed section 2062 and the second fixed section 2063 include the following situations: First, a plurality of second mounting holes 2062b are formed on the first fixed section 2062, and there are a plurality of avoidance holes 2062a, and the plurality of avoidance holes 2062a and the plurality of second mounting holes 2062b are alternately arranged along the second direction. Second, a plurality of third mounting holes 2063a are formed on the second fixed section 2063, and the plurality of third mounting holes 2063a are alternately arranged along the second direction. Third, a plurality of second mounting holes 2062b are formed on the first fixed section 2062, and there are a plurality of avoidance holes 2062a, and the plurality of avoidance holes 2062a and the plurality of second mounting holes 2062b are alternately arranged along the second direction. At the same time, a plurality of third mounting holes 2063a are formed on the second fixed section 2063, and the plurality of third mounting holes 2063a are alternately arranged along the second direction (such as Figure 13 shown).

[0089] This arrangement increases the number of connection points between the electrical box insulation 206 and the electrical box 205, while the number of third mounting holes 2063a increases the number of connection points between the electrical box insulation 206 and the main body 1 of the generator 201. This further improves the connection stability between the electrical box insulation 206 and the electrical box 205, further improves the connection stability between the electrical box insulation 206 and the main body 1 of the generator 201, and improves the operational stability of the electrical box insulation 206, thereby reducing the possibility of fatigue fracture and improving NVH performance. Furthermore, the multiple second mounting holes 2062b do not interfere with other components, maintaining a simple structure while ensuring the vibration level of the insulation structure.

[0090] According to some embodiments of the present invention, referring to Figure 13 The free end of the second fixing section 2063 has a folded edge 2063b, which extends along the thickness direction of the second fixing section 2063 in a direction away from the heat insulating section 2061. The free end surface of the folded edge 2063b is in the same plane as the plane where the inlet of the exhaust manifold 2 is located. Figure 13 In the example, the folded edge 2063b is located at the right end of the second fixed section 2063, and the folded edge 2063b extends downward. The plane where the lower end surface of the folded edge 2063b (i.e., the free end surface of the folded edge 2063b) lies is coplanar with the plane where the inlet of the exhaust manifold 2 lies. This arrangement allows the electric control box insulation 206 to completely shield the heated area of the electric control box 205, thereby improving the insulation performance of the electric control box insulation 206 and effectively reducing the heating of the electric control box 205. In addition, the rigidity of the electric control box insulation 206 is enhanced, and the service life of the electric control box insulation 206 is extended. It should be noted that the lower end surface of the folded edge 2063b is coplanar with the inlet flange of the exhaust manifold 2.

[0091] Optionally, the electrical control box insulation 206 is an integrally formed part. This improves the structural strength of the electrical control box insulation 206, prevents fatigue fracture of the electrical control box insulation 206 under strong vibration conditions, and extends the service life of the electrical control box insulation 206. The electrical control box insulation 206 is stamped and formed using a fully wrapped edge method, with the inner layer, middle layer, and outer layer being located between the inner and outer layers. The inner and outer layers can be metal parts, and the middle layer can be an air layer or insulation 3, thereby helping to further improve the thermal insulation effect of the electrical control box insulation 206. The electrical control box insulation 206 is electrophoretically treated to make its surface smooth, effectively reducing the impact of radiant heat exchange on the electrical control box 205. It should be noted that the minimum distance between the front end of the exhaust manifold 2 and the right side of the electrical control box 205 is less than 70 mm, for example, the minimum distance is 62 mm. The exhaust manifold 2 poses a risk of thermal damage to the electrical control box 205.
