Abstract

The invention discloses a double compressor impeller supercharger, comprising a no-blade turbine housing, a turbine wheel, a bearing pedestal, a compressor casing, a bearing, a compressor impeller 1 and a compressor impeller 2. The supercharger is characterized in that the no-blade turbine housing is internally provided with the turbine wheel, the turbine wheel is connected with the bearing pedestal, the bearing pedestal is connected with the compressor casing, the compressor casing is internally provided with the bearing, the bearing is provided with the compressor impeller 1 and the compressor impeller 2. A conventional single compressor impeller supercharger is improved to the double compressor impeller supercharger, and air is compressed again after being compressed, so as to improve compressed air velocity, reduce temperature of pressurized air, and improve volumetric efficiency. Thus, combustion of an engine is more sufficient, and an objective of reducing emission is achieved. The double compressor impeller supercharger is simple in design, easy in assembling, reduced in cost, and reduced in intake air temperature. Dynamic property of the engine is improved while volume of the engine is not changed. The double compressor impeller supercharger is stable in performance and good in reliability, and the engine is more compact and beautiful.

Description

technical field

[0001] The invention relates to the field of engines, in particular to a dual-compressor impeller supercharger. Background technique

[0002] The supercharger of the prior art is a single compressor wheel mechanism, but this supercharger has the following disadvantages:

[0003] First, the air intake efficiency is low. Since the supercharger is compressed air filtered by the air filter, the air filter has intake resistance, which causes part of the air after the supercharger is compressed to overcome the intake resistance. Loss, low air intake efficiency, incomplete combustion, increased emissions.

[0004] Second, the single-compressor impeller supercharger cannot meet people's requirements for smaller and stronger engines. If you want to increase the power of the engine, you must sacrifice the volume of the engine (increase the number of engine cylinders or increase the bore of the engine), increasing the cost. Increase in size.

[0005] Three, the tempe...
