Abstract

The invention discloses a double-driving parallel sequential supercharging compressor which comprises a compressor casing and a compressor impeller installed in the compressor casing. A compressor flow path is arranged in the compressor casing, and a compressor air inlet and a compressor air outlet which both communicate with the compressor flow path are arranged on the compressor casing. The compressor impeller is provided with an impeller air inlet flow path which communicates with the compressor air inlet and the compressor flow path. The double-driving parallel sequential supercharging compressor of the invention can effectively improve the compressor surge when the compressor is under a low speed condition, and effectively expand intake air flow when the compressor is under a middle or high speed condition and improve engine performance. The compressor casing and the compressor impeller of the double-driving parallel sequential supercharging compressor of the invention has good structural inheritance, and engineering is easy to be realized rapidly.

Description

technical field

[0001] The invention relates to a booster compressor, in particular to a dual-drive parallel sequential booster compressor with a double-channel compressor casing and a single compressor impeller, which belongs to the field of internal combustion engine booster. Background technique

[0002] The turbocharger uses the energy of the exhaust gas discharged from the engine to drive the turbine to rotate, thereby driving the impeller of the compressor coaxial with the turbine to rotate at a high speed. The compressor pushes the compressed air into the engine cylinder, increasing the air volume of the engine. Driven by the flow rate, the combustion is more complete, thereby increasing the power of the engine, reducing fuel consumption, and reducing harmful emissions and noise.

[0003] In recent years, with the substantial increase in engine power per liter, the technical indicators of turbocharging also need to be continuously improved, which requires a turbocharg...
