In addition, a pressure sensor 3 and a temperature sensor 4 for measuring the intake pressure and intake temperature of the intake manifold are provided on the other side of the sleeve body 1. In addition, a channel 21 is provided on the connecting portion 2, and the channel 21 can be used to connect the sleeve body 1 with the intake manifold, and the probe 41 of the temperature sensor 4 can pass through the sleeve body 1 and the channel to extend into the intake manifold. In this way, the sleeve body 1 is connected to the intake manifold through the channel 21 of the connecting portion 2; by providing a pressure sensor 3 and a temperature sensor 4 on the other side of the sleeve body 1, when the connecting portion 2 is installed on the intake manifold, the sleeve body 1 is connected to the intake manifold, so that the pressure and temperature of the intake manifold can be detected by the pressure sensor 3 and the temperature sensor 4; by providing the measuring device, it is possible to reduce the number of holes drilled on the intake manifold, ensure the sealing of the intake manifold, and avoid damaging the structural strength of the intake manifold, thereby improving the performance of the engine.

[0029] For further information, see Figure 1 As shown, the connection part 2 includes a plug 22, the plug 22 is provided with the above-mentioned channel 21, the intake manifold is provided with a socket, and the plug 22 is matched and connected with the socket. In this way, by plugging the plug 22 with the socket, the connection and installation of the sleeve body 1 and the intake manifold are conveniently realized, and the sealing between the sleeve body 1 and the intake manifold can be ensured.

[0030] The working principle of this embodiment is as follows: the plug 2 is connected with the jack of the intake manifold to realize the connection between the sleeve body 1 and the intake manifold; the pressure and temperature of the intake manifold are detected by the pressure sensor 3 and the temperature sensor 4, so that the intake pressure and intake temperature of the intake manifold can be obtained; wherein, the probe of the temperature sensor 4 can pass through the sleeve body 1 and the channel and extend into the intake manifold, so that the temperature in the intake manifold can be detected.

[0031] Preferably, the cross section of the plug 22 is arranged in a circular ring shape. Thus, by being arranged in a circular ring shape, cutting and processing can be facilitated, thereby improving processing efficiency.

[0032] Preferably, a sealing gasket (not shown) is also provided on the plug 22. By providing the sealing gasket, the sealing performance between the plug 22 and the jack can be further ensured, thereby improving the sealing performance of the intake manifold.

[0033] For further information, see Figure 1 As shown, the outer diameter of the plug 22 is smaller than the outer diameter of the sleeve body. In this way, when the plug 22 is inserted into the jack of the intake manifold, the intake manifold can abut against the sleeve body 1, and the intake manifold is further blocked by the sleeve body 1, thereby further ensuring the sealing of the intake manifold and preventing air leakage of the intake manifold.

[0034] For further information, see Figure 1 As shown, the sleeve body 1 is further provided with an extension tube 5 in communication therewith, and the extension tube 5 is provided with a first fixing member 6, and the first fixing member 6 can be used to fix the pressure sensor 3 on the extension tube 5. By providing the extension tube 5, the pressure sensor 3 can be arranged on the extension tube 5, so that mutual interference between the pressure sensor 3 and the temperature sensor 4 can be avoided, and the accuracy of detection can be ensured.

[0035] Preferably, see Figure 2 As shown, the first fixing member 6 includes a nut 61 and a boss 62, the boss 62 is hollow inside, and the boss 62 is arranged on the side of the nut 61 facing the sleeve body 1. In this way, the nut 61 is threadedly connected with the pressure sensor 3, and the boss 62 is inserted into the extension tube 5, so that the pressure sensor 3 can be installed on the extension tube 5. Preferably, the nut 61 and the boss 62 are welded to form, so as to enhance the bonding force between the nut 61 and the boss 62 and improve the service life of the first fixing member 6.

[0036] Preferably, in this embodiment, the axial direction of the extension tube 5 is perpendicular to the axial direction of the sleeve body 1. The extension tube 5 is vertically distributed with the sleeve body 1, so that the pressure sensor 3 and the temperature sensor 4 can be effectively prevented from interfering with each other. Of course, in this embodiment, according to actual conditions and specific needs, the axial direction of the extension tube 5 can also be arranged to be distributed at other angles with the axial direction of the sleeve body 1, which is not limited here.

[0037] For further information, see Figure 1As shown, the sleeve body 1 is provided with a second fixing member 7, and the second fixing member 7 can be used to fix the temperature sensor 4 on the sleeve body 1. In the present application, the structure of the second fixing member 7 can be the same as that of the first fixing member 6, and threads can also be provided at both ends of the second fixing member 7, and the temperature sensor 4 can be installed on the sleeve body 1 through threaded connection. Of course, it can also be any other structure that can achieve fixation in the technical field of the present invention, and it is not limited here.

[0038] In the present application, by providing the first fixing member 6 and the second fixing member 7, the pressure sensor 3 and the temperature sensor 4 can be fixedly installed on the extension tube 5 and the sleeve body 1 respectively, thereby facilitating the installation and removal of the pressure sensor 3 and the temperature sensor 4.

[0039] Preferably, the sleeve body 1 and the extension tube are integrally formed, so that the structural strength of the measuring device can be ensured and the overall stability of the measuring device can be improved.
