Abstract: The dynamics of valve train is influenced by stiffness, size, and mass distribution of its components and initial valve clearance and so on. All the factors should be taken into consideration correctly by dynamic model and ...

Abstract: The engine vibration and noise induced by a valve train element are analyzed through the modeling and experiment method. The valve train dynamics are first studied to make clear the sources of the valve train noise. The ...

Abstract: The analysis of intake silencer insertion loss (IL) was conducted using a hybrid numerical method, which combined computational fluid dynamics (CFD) and acoustic finite element method (FEM). First, an experimental test was ...
