Embodiment Construction

[0011] Such as figure 1 , figure 2 Described a kind of twin wire spiral intake supercharger, comprises compressor air inlet 1, compressor wind deflector front section 2, compressor wind deflector 3, air intake duct 4, intermediate body 6, turbine shell 7 , the compressor inlet 1 adopts the double button line inlet path, such as figure 1 The compressor inlet 1 of the traditional supercharger adopts a right-angle or obtuse-angle linear structure, which hinders the flow of air to this place, generates eddy currents, and increases air flow resistance, thus reducing the pressure of the supercharger. The intake air volume reduces the efficiency of the supercharger. And the present invention is by utilizing the calculation of aerodynamic principle and fluid mechanics principle, and when air enters supercharger compressor air inlet 1, flows along double button line path, and the resistance that suffers is minimum, and flow energy loss is also minimum, therefore can improve booster ...

Abstract

The invention relates to a lemniscate spiral air inlet supercharger, which comprises a compressor air inlet, a compressor air guide wheel, a compressor air guide wheel front section, an air inlet, an intermediate, a turbine casing, wherein the compressor air inlet has a lemniscate air inlet path; and the compressor air guide wheel front section is provided with at least one spiral air entraining groove. The whole structure of the supercharger is not changed, parts are not additionally arranged, the air inlet of the supercharger is innovatively designed, inlet air flow resistance and flow energy loss are reduced, air is promoted to generate prewhirl, air flow is increased, and the efficiency of the supercharger is improved.

Description

【Technical field】 [0001] The invention relates to an engine assembly, in particular to a double-knuckle screw air intake supercharger. 【Background technique】 [0002] A turbocharger is a device that can increase engine power and reduce engine emissions, and is widely used in various engines. With the implementation of Euro IV and Euro V emissions, the air supply system of the engine is required to supply more air. Since the engine cylinder volume is fixed, the only way to increase the air supply is to further compress the intake air to increase the air intake. Therefore, the supercharger is required to have higher efficiency to meet the requirements of the engine. Due to the low efficiency and limited gas supply, the current ordinary supercharger can no longer meet the requirements of Euro IV and Euro V engines, which limits the development of superchargers. 【Content of invention】 [0003] In view of the problems existing in the current known technology, the technical pr...
