Abstract

The invention discloses a double-layer channel variable-section turbine control device, belonging to the field of an internal combustion engine. The double-layer channel variable-section turbine control device comprises a turbine housing, wherein the turbine housing is internally provided with a gas inlet inner channel and a gas inlet outer channel; the gas inlet outer channel is positioned at the outer side of the circumferential direction of the gas inlet inner channel; and a partition wall is arranged between the gas inlet outer channel and the gas inlet inner channel. The double-layer channel variable-section turbine control device is characterized in that the gas inlet inner channel is provided with a gas inlet; the position on the partition wall, close to the gas inlet, is provided with an outer channel gas inlet which is provided with a gas inlet control device; the double-layer channel variable-section turbine control device can effectively guarantee that the double-layer channel variable-section turbine meets the supercharging needs of the all condition range of the engine, simultaneously has no existence of potential unreliability of rotary vane type and axial movement type variable-section turbine supercharger and has simple and reliable products.

Description

technical field [0001] The invention relates to a turbine control device for a variable-section exhaust gas turbocharger, in particular to a double-layer channel variable-section turbine control device, which belongs to the field of internal combustion engines. Background technique [0002] In China, with the implementation of the National III emission regulations, people's demand for engine turbochargers that can take into account both high and low speed performance of the engine is becoming stronger and stronger. Variable cross-section turbochargers have become the focus of research and development at home and abroad, and are currently widely used The structure of the rotating nozzle vane is added inside the turbine and the structure of the diffuser channel is changed axially to meet the requirement of variable cross section. Rotary vane and axially adjustable variable cross-section turbochargers change the flow channel of the turbine by changing the opening between the no...
