Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
[0025] Such as figure 1 Shown is a longitudinal sectional view of an air compressor in a supercharged engine of the present invention, a rotating shaft 2 , an impeller 3 and impeller blades 4 of an air compressor are fixed together and are all located in a compressor housing 5 . The rotating shaft 2 can be driven by any energy, preferably a turbine wheel of a turbine (not shown). A first diffuser 6 and a second diffuser 7 are arranged inside the compressor casing 5 . The two diffusers are divided by a partition wall 8 . Fixed blades 9 are provided on the first diffuser 6 and the second diffuser 7 . Via the air inlet 10 , the intake gas flow 11 flows out of the compressor housing 5 rapidly through the impeller 3 . When the intake air flow 11 leaves the impeller blades 4 , it is split into two...

The invention discloses an air compressor of a supercharged engine. The air compressor of the supercharged engine comprises the air compressor and a modulated displacement engine. The air compressor is connected with the modulated displacement engine through guide tubes. The air compressor comprises an air compressor shell. An air inlet and a plurality of air outlets are formed in the air compressor shell. Air flows into the modulated displacement engine through the air outlets. A rotating shaft is arranged in the center of the air compressor shell and provided with an impeller. Diffusers are arranged on the periphery of the air compressor shell, and each diffuser corresponds to one air outlet. The air compressor of the supercharged engine has the advantages that the air compressor arrangement structure with two air outlets shifts surge limit to a region with a lower flow, the air compressor with the arrangement equivalently enables a plurality of air compressors to be arranged on the same shell body, the whole structure is simplified, a dividing wall separates the air, one of the air outlets is closed when the flow is low, and efficiency of the air compressor is improved.
Description
technical field [0001] The invention relates to an air compressor, in particular to an air compressor in a supercharged engine. Background technique [0002] Currently known technology, traditional supercharged internal combustion engines, such as supercharged or turbocharged engines, use an air compressor to supercharge the intake air of the internal combustion engine. By increasing the intake air density through supercharging, more air and fuel are introduced and combusted by the engine, thus increasing the output of the internal combustion engine. This compressor is a centrifugal compressor whose impeller can rotate around an axial shaft and is used to press the air introduced in the axial direction to the outer edge of the air compressor, the air outlet on the circumference of the outer edge and its downstream The diffuser converts the kinetic energy of the air into pressure. Diffusers are a technology used in centrifugal air compressors. Air flows into the diffuser a...
