Embodiment 1

[0036] Embodiment 1, as attached figure 1 , figure 2 As shown, a variable channel turbine air intake adjustment device includes a volute 1, an actuator 2 and an intake flow adjustment device 3 are installed on the volute 1, and the actuator 2 and the intake flow adjustment device 3. transmission connection, the volute 1 is installed with a waste gas bypass device 4, and the actuator 2 is connected with the waste gas bypass device 4 through transmission.

[0037] The executive device 2 can simultaneously control the intake air flow regulating device 3 and the waste gas bypass device 4, so as to realize the selection of the intake flow channel of the variable channel turbine, the control of the intake air flow and the control of the waste gas bypass volume, ensuring that the turbine While working efficiently, the variable section function of the supercharger is realized to meet the supercharging requirements of the engine under all working conditions.

[0038] The actuator 2 ...

Embodiment 2

[0050] Embodiment 2, as attached Figure 6 , Figure 7 As shown, when the variable channel turbine volute intake channel is changed to a pulsed double intake channel, a set of intake flow regulating devices 3 can also be connected to the two ends of the connecting pin shaft 9 to realize the dual channel variable flow channel. Adjustment of the intake of the turbine. The actuator push rod 7 is fixed on the connecting pin shaft 9 with a fixing nut 21, and its volute intake adjustment and waste gas bypass control are the same as in the first embodiment.

Abstract

The invention discloses an air inlet regulating device of a flow-passage-changeable turbine. The air inlet regulating device comprises a turbine shell, an executing device and an air inlet flow regulating device, wherein the executing device is in transmission connection with the air inlet flow regulating device; an exhaust gas bypass device is arranged on the turbine shell; and the executing device is in transmission connection with the exhaust gas bypass device. The executing device can control the air inlet flow regulating device and the exhaust gas bypass device at the same time, so as to select the air inlet flow passage of the flow-passage-changeable turbine and control the air inlet flow and the exhaust gas bypass flow; and on the premise of ensuring the high-efficiency work of the turbine, the section-changeable function of a supercharger is realized, and the requirement for the whole-working-condition pressurization of an engine can be met.

Description

technical field [0001] The present invention relates to a turbocharger with variable cross-section function and waste gas bypass function, in particular to a variable channel turbine intake regulating device for turbocharger with bypass function . Background technique [0002] In order to meet the high emission standards, the engine needs to use a variable section supercharger to control the intake and exhaust pressure, so that the supercharger and the engine can achieve a good match under various working conditions, but as the engine, especially the vehicle engine With the further improvement of power and torque, the adjustment range of the variable cross-section supercharger is getting wider and wider. Since the variable cross-section supercharger generally does not have a bypass and bleed function, this excessively wide adjustment range will lead to certain working conditions. Especially at low speeds the efficiency of the supercharger is too low. It has been found from...
