Embodiment Construction

[0026] Such as figure 1 As shown, the supercharger includes a turbine housing 4, an intermediate housing 7 with a raised portion in the middle, a turbine 5, and a turbine drive shaft. The exhaust gas turbine components are installed in the intermediate housing and fixed to the turbine housing. The turbine housing has a built-in turbine. The transmission shaft, the raised part of the intermediate shell is arranged at the root and bottom of the turbine, and the turbine is in the volute cavity. It is characterized in that the supercharger also includes a cap-shaped fixed vane nozzle ring 1 with a hole in the middle, a plurality of adjustable Vane nozzle 2, adjustable cylindrical nozzle 3 and two T-shaped levers 6, fixed nozzles 13 are evenly distributed on the side end surface of the fixed vane nozzle ring, and the fixed nozzles are arranged in the exhaust flow channel of the volute cavity and flow in the direction of the exhaust gas flow. With a certain inclination angle, the fi...

Abstract

The invention provides an adjustable turbocharger system which comprises a hat-shaped fixed blade nozzle ring, a plurality of adjustable blade nozzles, an adjustable cylindrical nozzle and two T-shaped levers, wherein a hole is formed in the middle of the fixed blade nozzle ring; fixed nozzles are uniformly distributed on the side end surface of the fixed blade nozzle ring; a transmission device used for controlling the T-shaped levers to perform axial motion is connected with the corresponding end parts of the T-shaped levers; the adjustable cylindrical nozzle is connected between the two T-shaped levers and takes the shape of a cylinder; the adjustable blade nozzles are fixed to the cylinder periphery of the adjustable cylindrical nozzle; and when the T-shaped levers perform axial motionin the directions of the fixed nozzles, the adjustable blade nozzles and the adjustable cylindrical nozzle are driven to correspondingly extend out of the end surface and the hole of the fixed bladenozzle ring. The nozzle outlet section area changes by the adoption of the axial moving mode and the minimum outlet section area can be achieved, so that the adjustable range of the adjustable turbocharger system is extended compared with that of the existing patented technology and the adjustable turbocharger system serves as a novel three-level variable nozzle structure.

Description

technical field [0001] The invention relates to an adjustable turbocharger system, which belongs to the technical field of machinery. Background technique [0002] At present, exhaust gas turbocharger technology has been widely used in internal combustion engines, which can increase the output power of internal combustion engines, reduce fuel consumption per unit power and reduce the discharge of harmful gases and harmful particles. However, due to the frequent change of working conditions of the vehicle engine, the supercharger will work in the non-efficient area during part of the working period, thereby reducing the supercharging effect and failing to meet the energy saving and emission reduction targets. [0003] In order to adapt the supercharger to the reality of the variable working conditions of the vehicle engine, the measure adopted now is to change the bladeless runner turbine casing 4 in the original structure into a three-stage nozzle with blades adjustable 1, 2...
