Embodiment 1

[0049] Example 1, such as figure 2 and image 3 As shown, a variable cross-section double-channel intake turbine includes a turbine volute 4, a volute nozzle 6 is provided on the turbine volute 4, a turbine impeller 8 is installed in the turbine volute 4, and the turbine volute 4 is provided with a volute inlet flow passage 10, and an intermediate wall 20 is arranged inside the volute inlet flow passage 10, and the intermediate wall 20 separates the volute inlet flow passage 10 into a small volute inlet flow passage 18 and a volute inlet flow passage. Air large flow channel 19, the flow area of ​​the volute intake small flow channel 18 is less than the flow area of ​​the volute intake large flow channel 19, the volute intake small flow channel 18 and the volute intake large flow channel 19 are both gas.

[0050] The radial section of the intermediate wall 20 is an arc-shaped structure, one end of the intermediate wall 20 is fixedly connected to the turbine volute 4, and the...

Embodiment 2

[0059] Example 2, such as Figure 7 As shown, in Embodiment 1, the positions of the large air intake channel of the volute and the small air intake channel of the volute can also be exchanged, and the position of the air intake adjustment control mechanism is readjusted, and the rest are the same.

[0060] The small volute air intake channel 18 is located outside the large volute air intake channel 19. When the engine is at low speed, only the small volute air intake channel 18 realizes air intake. When the engine is running at medium and high speeds, the air intake adjustment control mechanism 16 controls the intake air adjustment valve 15 to form different openings, and controls the gas flow entering the volute intake small flow channel 18 and the volute intake large flow channel 19 to realize flow Channel selection and flow capacity control to achieve matching with the engine at medium and high speeds.

[0061] The small volute intake flow channel 18 is located outside the...

Embodiment 3

[0063] Example 3, such as Figure 8 As shown, in Embodiment 1, several airflow guide vanes 21 can be provided at the nozzle of the volute intake large flow passage 19, and several airflow guide vanes 21 are arranged in a semicircular arc shape, and are installed obliquely along the turbine rotation direction, To ensure that the outlet airflow of the volute intake large flow channel 19 enters the turbine at a prescribed angle. Adopting this technical solution can improve the energy utilization efficiency of the exhaust gas at medium and high speeds of the engine, and effectively prevent the outlet airflow at the end of the small volute air intake channel 18 from entering the large volute air intake channel 19 at low engine speeds.

Abstract

The invention discloses a variable section double-channel air intake turbine, comprising a turbine volute, wherein the turbine volute is provided with a volute nozzle; a turbine wheel is installed in the turbine volute; the turbine volute is provided with a volute air intake channel; a middle wall is arranged in the volute air intake channel and separates the volute air intake channel into a small volute air intake channel and a big volute air intake channel; and the radial section of the middle wall is of arc structure, with radian of 60-180 degrees. The turbine changes the position of the end of the middle wall on the circumference through reasonable separation of the middle wall, thus changing the corresponding air intake area angles of the big and small channels and being capable of realizing that the air intake area angle of the small volute air intake channel changes between 60 degrees and 180 degrees and the corresponding air intake area angle of the big volute air intake channel changes between 300 degrees and 180 degrees.

Description

technical field [0001] The invention relates to a variable cross-section supercharger, in particular to a variable cross-section double-channel intake turbine with different flow cross-sectional areas, which can effectively meet the high and low speed supercharging requirements of the engine, and belongs to the field of internal combustion engine supercharging. Background technique [0002] With the gradual improvement of emission standards, superchargers are widely used in modern engines. In order to meet the performance and emission requirements of the engine under all operating conditions, the supercharger must have the adjustable function of boost pressure and exhaust pressure. With the implementation of the National IV emission regulations, variable cross-section superchargers have become the focus of research and development at home and abroad. At present, the structure of adding rotating blades to the nozzle of the turbine volute is generally used to meet the require...
