An Acoustic Design Procedure for Intake Systems: 1D Analysis and Experimental Validation 2004-01-0412
The paper details recent results concerning the design of a new intake system for a 1.4 liter displacement ELASIS-FIAT engine. A classical approach, based on theoretical one-dimensional characterization of the whole system, is presented. This approach, however, requires a relevant number of geometrical information which are usually unavailable in the first phase of the design process.
For this reason, a statistical analysis on a number of existing devices was also carried out to the aim of providing such initial data as a function of prescribed levels of pressure losses and noise emission for the device.
The methodology allows then to define a base configuration of the system, to start the 1D analyses. The base geometry is further refined taking into account the layout constraints and the presence of resonators for the reduction of the noise emission.
Experimental data collected on a prototype of the designed system have confirmed the robustness of the whole design procedure.
