[0022] The following is combined with Figure 1 The utility model is described in further detail.

[0023] The utility model embodiment discloses a supercharged engine air intake system.

[0024] Reference Figure 1A supercharged engine intake system includes a cylinder head cover 1 and an intercooler 5. A supercharger interface 2 is provided on the cylinder head cover 1. An intercooler intake passage 3 is provided on the cylinder head cover 1. The intake end of the intercooler intake passage 3 is connected with the supercharger interface 2, and the outlet end is connected with the intake end of the intercooler 5. The outlet end of the intercooler 5 is connected with the intake manifold 8 through a throttle valve 7. The intake system has no hose connection, the intake passage has an inclined angle, there is no risk of condensation water accumulation, and an integrated design is adopted, the layout is compact, and the whole vehicle layout is easy, and the intercooler 5 intake pipe and the intercooler 5 outlet pipe are cancelled, and the cost is low.

[0025] In this embodiment, the supercharger interface 2 is obliquely arranged on the cylinder head cover 1, serving as a supercharged gas inlet, and the supercharger interface 2 is a supercharged pipe, which is used to connect with the supercharger. The supercharged gas discharged by the supercharger enters the intercooler intake passage 3 through the supercharger interface 2, replacing the hose setting of the traditional intake system.

[0026] The intercooler air intake passage 3 is directly integrated into the cylinder head cover 1, and the air outlet end of the intercooler air intake passage 3 is directly connected to the air intake end of the intercooler 5, replacing the traditional intercooler 5 air intake pipe, eliminating the need to arrange the intercooler 5 air intake pipe separately, saving space, making the structure more compact, reducing the engine size, and facilitating the overall vehicle layout.

[0027] In this embodiment, the intercooler air intake passage 3 is provided with an inclined surface. The pressurized gas discharged from the supercharger enters the intercooler air intake passage 3 to form an airflow, and the inclined angle between the inclined surface and the airflow direction of the pressurized gas there is in the range of 2-5°. The inclined surface is used to guide the condensed water into the cylinder. Since the airflow speed of the pressurized gas is relatively fast, the condensed water can be discharged from the cylinder through the airflow of the pressurized gas, and the excess condensed water can be discharged through the exhaust port of the cylinder, or a separate drain port can be opened for discharge.

[0028] In addition, the air intake system has no hose connection, the air intake channel has an inclined angle, and the outlet end of the intercooler air intake channel 3 is directly connected to the air intake end of the intercooler 5. The above structure can greatly reduce the risk of condensed water accumulation and avoid fire in the cylinder.

[0029] An RCV valve 4 is integrated on the cylinder head cover 1, and the air outlet end of the RCV valve 4 is directly connected to the intercooler intake passage 3, and the air intake end of the RCV valve 4 is connected to the supercharger. The traditional RCV valve 4 requires an additional air outlet pipe to be provided for connecting with the intercooler 5, while the utility model is directly integrated in the cylinder head cover 1 and is connected to the intercooler intake passage 3, and can be connected to the intercooler 5 through the intercooler intake passage 3, with a compact layout, space saving, easy vehicle layout, and low cost.

[0030] The throttle valve 7 is arranged on the cylinder head cover 1, and the outlet end of the intercooler 5 is connected with the intake manifold 8 through the throttle valve 7, eliminating the outlet pipe of the intercooler 5 in the intake system, so that the intake pressure loss of the intake system is small, the control accuracy of the throttle valve 7 is high, and the engine performance can be improved.

[0031] The intercooler 5 is provided with a mounting base 6, and an intake air temperature and pressure sensor is integrated on the mounting base 6. In the conventional arrangement, due to the existence of the intercooler 5 outlet pipe, in order to ensure the accuracy of temperature detection, it is necessary to set the intake air temperature and pressure sensor on both the intercooler 5 and the intake manifold 8. However, in the utility model, since the intercooler 5 is directly connected to the intake manifold 8 through the throttle 7, the temperature damage caused by the intermediate spacing distance can be ignored. Therefore, it is only necessary to set the intake air temperature and pressure sensor on the intercooler 5, which is compactly arranged, saves space, is easy to arrange in the whole vehicle, and has low cost.

[0032] A high-pressure desorption joint 9 is integrated on the intercooler 5, and a high-pressure desorption joint 2 10 is integrated on the cylinder head cover 1. The high-pressure desorption joint 9 and the high-pressure desorption joint 2 10 are respectively connected to the high-pressure desorption system. By integrating the high-pressure desorption joint 9 and the high-pressure desorption joint 2 10, the layout is compact, space is saved, the whole vehicle layout is easy, and the cost is low.

[0033] The structure of the utility model can shorten the air intake system pipeline, improve the air intake uniformity, make each cylinder burn evenly, and improve the engine performance.

[0034] The present invention also provides a vehicle, which includes the above-mentioned supercharged engine intake system. Since the vehicle adopts all the above-mentioned technical solutions, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
