It is usually a structure with side intake and end exhaust. The engine exhaust enters from the inlet of the three-way catalytic converter, passes through the internal carrier catalyst after being disturbed by the spoiler pipe, and is then discharged through the exhaust pipe. If a natural gas engine misfires, the internal carrier catalyst of the three-way catalytic converter will be ablated and fail, so the actual state of the internal carrier catalyst needs to be confirmed.

[0032] Figure 1 The internal structure diagram of the three-way catalytic converter provided by the embodiment of the utility model is as follows: Figure 1 As shown, the utility model provides a three-way catalytic converter 10, comprising: a shell 1, an inner cavity 11 of which is provided with an internal carrier catalyst 2; a spoiler tube 3, part of which is located in the inner cavity 11, and a side wall of the spoiler tube 3 located in the inner cavity 11 is provided with a plurality of spoiler holes 32 and at least one first observation hole 31, and the first observation hole 31 is used to avoid an endoscope so that the endoscope can pass through the first observation hole 31.
[0033] In this embodiment, when a natural gas engine misfires, the internal carrier catalyst 2 can be observed by simply inserting the endoscope into the inner cavity 11 through the first observation hole 31, thereby accurately confirming the state of the internal carrier catalyst 2 without disassembling the three-way catalytic converter 10.
[0034] Among them, the first observation hole 31 can be a round hole. Since the diameter of the commonly used endoscopic probe is 6 mm, the diameter range of the first observation hole 31 can be set to 8 mm-15 mm. For example, 12 mm can be selected so that the endoscopic probe can easily pass through the first observation hole 31.
[0035] It should be noted that the specific size of the diameter of the first observation hole 31 in the present embodiment is for illustration only and should be set according to the size of the actual endoscopic probe and the actual operating conditions. It is sufficient to ensure that the endoscopic probe can be easily inserted into and removed from the first observation hole 31, and there is no specific limitation on the size.
[0036] refer to Figure 1 According to an optional embodiment of the present utility model, there are multiple first observation holes 31, and the multiple first observation holes 31 are arranged at intervals.
[0037] In this embodiment, since there are multiple first observation holes 31, the positions where the endoscope probe can be inserted into the inner cavity 11 are increased, so the endoscope probe can be more conveniently inserted into the inner cavity 11, thereby confirming the state of the internal carrier catalyst 2.
[0038] Continue to refer Figure 1 According to an optional embodiment of the present utility model, the first observation holes 31 are evenly spaced;
[0039] In this embodiment, for example, a plurality of first observation holes 31 may be evenly spaced around the circumference of the side wall of the spoiler tube 3, such as Figure 1 This arrangement is simple in process and convenient in processing, and it is also convenient for the endoscope probe to extend into the inner cavity 11, thereby improving the efficiency of confirming the state of the internal carrier catalyst 2.
[0040] Figure 2 A side view of a three-way catalytic converter provided by an embodiment of the utility model, referring to Figure 1 and Figure 2 According to an optional embodiment of the utility model, the three-way catalytic converter further includes: an exhaust pipe 4, the exhaust pipe 4 is connected to the inner cavity 11, the exhaust pipe 4 is located on the side of the internal carrier catalyst 2 away from the spoiler pipe 3, and the exhaust port of the exhaust pipe 4 close to the side of the internal carrier catalyst 2 is provided with a baffle 5, and the baffle 5 is provided with an exhaust hole 51. .
[0041] The baffle 5 may be welded to the exhaust port of the exhaust pipe 4 on the side close to the internal carrier catalyst 2 .
[0042] In this embodiment, the baffle 5 can effectively reduce the loss of the internal carrier catalyst 2. If someone steals the internal carrier catalyst 2, the baffle 5 must be damaged, which is convenient for market judgment. In addition, since the baffle 5 is provided with an exhaust hole 51, the exhaust gas can be discharged to the atmosphere through the exhaust hole 51 after passing through the internal carrier catalyst 2.
[0043] Therefore, the setting of the baffle 5 can reduce the loss of the internal carrier catalyst 2 without affecting the exhaust gas discharge, and if the internal carrier catalyst 2 is lost, it can also facilitate the time judgment.
[0044] refer to Figure 2 According to an optional embodiment of the present invention, there are multiple exhaust holes 51 , and the multiple exhaust holes 51 are evenly spaced and distributed on the baffle 5 .
[0045] In this embodiment, the exhaust holes 51 can be evenly spaced throughout the baffle 5. Figure 2 As shown. In this way, the exhaust gas can be discharged into the atmosphere more smoothly and evenly, ensuring the efficiency of exhaust gas discharge.
[0046] Continue to refer Figure 2 According to an optional embodiment of the present utility model, a second observation hole 52 is further provided on the baffle 5 , and the second observation hole 52 is used to avoid the endoscope so that the endoscope can pass through the second observation hole 52 .
[0047] Similarly, the second observation hole 52 can be a round hole. Since the diameter of a commonly used endoscopic probe is 6 mm, the diameter range of the second observation hole 52 can be set to 8 mm-15 mm. For example, 12 mm can be selected so that the endoscopic probe can be easily inserted into and pulled out of the second observation hole 52.
[0048] It should be noted that the specific size of the diameter of the second observation hole 52 in the present embodiment is for illustration only and should be set according to the size of the actual endoscopic probe and the actual operating conditions, so as to ensure that the endoscopic probe can be easily inserted into and pulled out of the second observation hole 52, and there is no specific limitation on the size.
[0049] In this embodiment, the setting of the second observation hole 52 enables the endoscope to penetrate into the inner cavity 11 through the exhaust pipe 4 to observe the internal carrier catalyst 2; combined with the setting of the first observation hole 31, this three-way catalytic converter 10 can be observed from the front and rear ends of the internal carrier catalyst 2 without disassembling the three-way catalytic converter 10, thereby more accurately confirming the state of the internal carrier catalyst 2.
[0050] Therefore, this arrangement can improve the accuracy of confirming the state of the internal carrier catalyst 2.
[0051] like Figure 2 As shown, according to an optional embodiment of the present invention, the second observation hole 52 is arranged at the center of the baffle 5.
[0052] In this embodiment, since it is necessary to insert the endoscope probe into the second observation hole 52 to confirm the state of the internal carrier catalyst 2, the second observation hole 52 is set at the center of the baffle 5. Then, when the endoscope probe is inserted into the second observation hole 52, its position is also located in the middle of the cavity of the exhaust pipe 4, which is convenient for observing the internal carrier catalyst 2.
[0053] The utility model also provides an exhaust system, comprising any one of the above three-way catalytic converters 10.
[0054] In this embodiment, the beneficial effects of the exhaust system are the same as those of any of the above-mentioned three-way catalytic converters 10, which are both capable of accurately confirming the state of the internal carrier catalyst 2 without disassembling the three-way catalytic converter 10, and will not be repeated here.
[0055] The utility model also provides a vehicle, comprising a vehicle body and the above-mentioned exhaust system.
[0056] In this embodiment, the beneficial effects of the vehicle are the same as the beneficial effects of the exhaust system described above, and will not be described in detail here.
[0057] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
