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 meshing and supercharging by the gears and rotors fixed on the two shafts, the noise is relatively large during operation, and the structure is relatively complicated and bulky. Large, low volumetric efficiency through dual gear boosting

Abstract

The present invention belongs to the field of engine technology, and is especially mechanical supercharger for motorcycle and automatic engine. The mechanical supercharger includes a casing with air inlet pipe and exhaust pipe, a eccentric columnar rotor, a coupler mounted to one end of the rotor, and movable blades mounted onto the surface of the rotor. The mechanical supercharger is connected via the coupler to a rotation mechanism rotating its rotor. It operates on the eccentric rotor and supercharging body to realize scavenging supercharging of the blades. It has blade slots in special angle to reduce friction between blades and the casing and vibration and raise scavenging effect. The mechanical supercharger has simple structure, small size and high supercharging effect, and is suitable for use in motorcycle and automatic engine.

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 1000°C. Its power is directly driven by the engine's own transmission system to drive its rotor. It is affected by the engine speed during operation, and has disadvantages such as slow response speed and short life. A mechanical supercharger for an internal combustion engine disclosed in a Chinese patent (ZL200410023340.2). The supercharger is a driving synchronous gear and a driven synchronous gear that are mounted on two shaft ends and mesh with each other. The three-lobe rotor and the three-lobe rotor whose end surface profile is a conjugate curve have a cylindrical structure or a twisted-lobe structure. Compare...
