an engine intake system 100, an engine 200, an engine intake pipe 201,
The air intake system includes an intake main pipe 10, a first intake branch pipe 21, a second intake branch pipe 22, an intercooler 30, a supercharger 40, an opening and closing valve 50, a throttle valve 60, an air cleaner 70, and a confluence pipe 80.
Detailed Description
It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
According to the utility model discloses an engine air intake system 100 for vehicle includes: main intake pipe 10, first intake branch pipe 21, second intake branch pipe 22, intercooler 30, supercharger 40, and opening and closing valve 50.
Wherein, the first air inlet branch pipe 21 is communicated with the main air inlet pipe 10, the second air inlet branch pipe 22 is communicated with the main air inlet pipe 10, and the second air inlet branch pipe 22 is connected in parallel with the first air inlet branch pipe 21.
An intercooler 30 is provided in the first intake branch pipe 21 for cooling the gas in the first intake branch pipe 21 to lower the temperature of the gas entering the engine 200.
The supercharger 40 is disposed in the main intake pipe 10, and the supercharger 40 is in communication with the main intake pipe 10, the supercharger 40 can compress the gas in the main intake pipe 10 to increase the density of the gas, and the compressed gas enters the engine 200 after flowing through the first intake branch pipe 21 or the second intake branch pipe 22, so that more gas enters the engine 200, and the power of the engine 200 is increased.
Wherein, the open-close valve 50 is arranged at the intersection of the main intake pipe 10 and the first intake branch pipe 21 and/or the main intake pipe 10 and the second intake branch pipe 22. Thus, the on-off valve 50 can selectively communicate the main intake pipe 10 with the first intake branch pipe 21, and the on-off valve 50 can also selectively communicate the main intake pipe 10 with the second intake branch pipe 22. Thereby, the on-off valve 50 can control the flow path of the gas in the main intake pipe 10. It is understood that the opening and closing valve 50 may control the communication state of the first and second intake branch pipes 21 and 22 with the intake main pipe 10.
Specifically, air may enter the engine intake system 100 through the intake main 10, and the air flows toward the engine 200 after being compressed by the supercharger 40. After the air is compressed by the supercharger 40, the density of the air increases and the temperature of the air increases. At this time, the main intake pipe 10 communicates with the first intake branch pipe 21, and the compressed air enters the first intake branch pipe 21, is cooled by the intercooler 30, and then enters the engine 200, thereby preventing high-temperature gas from entering the engine 200 to reduce the heat load of the engine 200, and increasing the intake air amount to increase the power of the engine 200.
When the vehicle travels in a region where the ambient temperature is low and the humidity is high, the temperature of the gas compressed by the supercharger 40 is low and the humidity is high. At this time, the main intake pipe 10 communicates with the second intake branch pipe 22, and the compressed air enters the engine 200 after passing through the second intake branch pipe 22. It can be understood that when low-temperature and high-humidity gas enters the first intake branch pipe 21, icing of the pipeline is easily caused, thereby affecting the power of the engine 200.
The communication state of the first intake branch pipe 21 and the second intake branch pipe 22 with the main intake pipe 10 may be controlled according to the ambient temperature. Such as: when the ambient temperature is lower than twenty degrees centigrade below zero, the second air inlet branch pipe 22 is communicated with the air inlet main pipe 10, and the first air inlet branch pipe 21 is not communicated with the air inlet main pipe 10; when the ambient temperature is not lower than twenty degrees centigrade below zero, the first air intake branch pipe 21 is connected with the main air intake pipe 10, and the second air intake branch pipe 22 is not connected with the main air intake pipe 10.
According to the utility model discloses an engine air intake system 100 for vehicle, on-off valve 50 is used for controlling the on-state of first air intake branch 21 and second air intake branch 22 and air inlet main pipe 10 to the route of control air admission engine 200, with the environment phase-match of engine air intake system 100 rather than the during operation better, promote the operational reliability of engine air intake system 100 in low temperature, high humidity environment.
In some embodiments of the present invention, as shown in fig. 1, an opening and closing valve 50 is disposed at the intersection of the first intake branch pipe 21 and the second intake branch pipe 22 between the intercooler 30 and the supercharger 40, and the connection state between the main intake pipe 10 and the first intake branch pipe 21 and between the main intake pipe 10 and the second intake branch pipe 22 can be controlled by controlling the opening and closing valve 50. It is understood that, when the open-close valve 50 is provided at the intersection of the first intake branch pipe 21, the second intake branch pipe 22, and the intake main pipe 10, the control of both branches can be achieved by providing only one open-close valve 50.
In a further embodiment of the present invention, the on-off valve 50 is a three-way valve, the three-way valve is connected to the main intake pipe 10, the first intake branch pipe 21 and the second intake branch pipe 22 respectively, and the three-way valve has a simple structure, so as to control the on-state of the main intake pipe 10 with the first intake branch pipe 21 and the second intake branch pipe 22.
Specifically, the opening and closing valve 50 may open the main intake pipe 10 and the first branch intake pipe 21, and not open the main intake pipe 10 and the second branch intake pipe 22, and the gas in the main intake pipe 10 flows through the first branch intake pipe 21 and then enters the engine 200; the on-off valve 50 may be opened to connect the main intake pipe 10 and the second intake branch pipe 22 and not to connect the main intake pipe 10 and the first intake branch pipe 21, and at this time, the gas in the main intake pipe 10 flows through the second intake branch pipe 22 and enters the engine 200.
