Fit Clearance of Impeller to Turbocharger Performance Influence with Mechanics Properties

Article Preview

Abstract:

The fit clearance between the impeller and the impeller shell directly affect the characteristics of the turbocharger. Assembly dimension chain is the basis of the design and analysis of workpiece size.Reducing the fit clearance of the impeller and the impeller shell can improve the booster effect. The impeller of the small inertia is beneficial to increase the rotation speed of the impeller and the impeller rotation stability requirements.The turbocharger of installation small inertia impeller is characterized by small size. Followed by its supercharged performance
