Study Regarding the Influence of the Fuel Tank Constructive Characteristics on Slosh-Noise Effect

Abstract

The aim of this article is to highlight the impact of the fuel movements inside the plastic fuel tank (waves) for the client perception of noise. Today there isn’t a clear methodology regarding the reproducing the fuel waves, but there are different approaches to be taken into account and also there is an innovative potential. Due to the fast technological progress the body in white and not only, the entire vehicle became lighter and lighted. A consequence of this great achievement is that the client can hear easier the sound produced by different components of the car. The plastic fuel tank can be considered such a component. The authors have done a deep analysis of present automotive fuel tanks and propose solutions for breaking the waves produced inside fuel tanks, so as to reduce the slosh noise effect. The studies will be continued during the doctoral approach of the first author.
