Internal combustion engine variable geometry turbine supercharger nozzle ring components

Abstract

The invention discloses an internal-combustion engine variable geometry turbocharger nozzle ring component, comprising forks(1), a mounting plate(2) and a blade(3), wherein the side surface of the mounting plate(2) is provided with a plurality of groups of blades(3) which are evenly spaced and arranged on the same circumference and are in the same direction, each group of blades which consists of at least three blades(3) and can be mutually opened and folded simultaneously; the other side of the mounting plate is provided with forks(1) which are connected with corresponding blades; because the blades are the three dimensional curved surface, air inlet passages for blades are continuously changed, the air input of the turbocharger is also continuously changed according to the working condition of the engine, thereby the engine can get proper amount of pressurized air under all conditions, which makes that the engine always runs under a reasonable condition, thereby realizing that the turbocharger increases the output power of the engine by 30 to 100 percent, reducing the emission of harmful gas by more than 10 percent, realizing that the fume emission reaches the emission standard of the European IV, lowering oil consumption by 5 to 10 percent and improving the economical efficiency of the automobile.

Description

technical field [0001] The invention relates to a turbocharger for an internal combustion engine, in particular to a nozzle ring assembly for a turbocharger for an automobile engine. Background technique [0002] At present, most of the cars are equipped with superchargers that match the engines, especially most of the cars need to be equipped with exhaust gas turbochargers to increase the output power of the car engine, reduce the emission of harmful exhaust gases, and reduce fuel consumption. , save energy, better adapt to the plateau environment, and compensate for the power loss caused by the thin air on the plateau. The nozzle ring assembly is a major key component in today's advanced variable geometry turbocharger, its quality directly affects the working performance of the turbocharger, and the key to affecting the working performance of the nozzle ring assembly is multiple The rotating shaft rotates the nozzle ring blades, and the combination of blades forms the air...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problems in the above-mentioned prior art that the nozzle ring assembly has small changes in the air intake channels between the blades, low pressure adjustment performance and blade material properties that cannot better meet the use requirements, the present invention provides a nozzle ring assembly that not only The change rate of the channel area between the blades is large, the gas flow and rate adjustment performance is good, and the blades have good wear resistance under high temperature and high pressure, strong impact and creep resistance, and a turbocharger nozzle ring assembly that is not easily oxidized
