Problems solved by technology

Compared with the turbocharger, the above-mentioned supercharger has a faster response speed and a longer service life; however, due to the radial arrangement of the vane and the vane groove, the friction between the outer end of the vane and the inner wall of the housing is relatively large when the vane rotates, and the supercharger vibrates greatly. , noisy, low volumetric efficiency, poor scavenging effect

Abstract

The invention belongs to the field of engines, in particular to a motorcycle or automobile engine supercharger. The invention includes an air intake pipe and an exhaust pipe installed at both ends of the casing, an eccentric cylindrical rotor is installed in the casing, a coupling is installed at one end of the rotor, the blades are loosely installed on the rotor cylinder, and several long blades are opened on the rotor cylinder Slot, the strip-shaped blade is inserted in the blade slot, the inner end of the blade slot is clockwise deflection angle a relative to the rotor axis, wherein the deflection angle a is 30° to 32°. The cross-sectional area of ​​the air inlet of the supercharging device is larger than that of the exhaust port, and the air pressure of the gas at the exhaust port increases to achieve the purpose of blade scavenging and supercharging. The special angle of the blade groove can improve the friction and vibration between the blade and the shell, and enhance the scavenging effect. The above-mentioned device has simple structure, small volume and good supercharging effect, and is suitable for supercharging engines of automobiles and motorcycles.

Description

Technical field: [0001] The invention belongs to the field of engines, in particular to a motorcycle or automobile engine supercharger. Background technique: [0002] Existing engines mainly adopt turbochargers and superchargers for supercharging. The turbocharger is driven by the high-temperature exhaust gas discharged from the engine at a temperature of nearly 100°C. Its power is directly driven by the engine's own drive train to drive its rotor. It is affected by the engine speed during operation, and has disadvantages such as slow response speed and short life. The British patent discloses a mechanical supercharger (GB2197389A). An eccentric cylindrical rotor is installed in the housing, and a coupling is installed at one end of the rotor. There are 3 elongated blade slots on the rotor cylindrical surface, and each blade slot is inserted There are elongated blades, and the blade grooves are arranged radially. Compared with the turbocharger, the above-mentioned supercha...
