Abstract
An experimental and numerical work has been performed to characterize the performance of a medium-size spark-ignition engine and the related gas-dynamic noise emitted at the intake mouth.
The noise attenuation of the main component of the intake system, namely the air flow box, has been experimentally measured and compared to the numerical results obtained using a tri-dimensional code. Then, the 3D-CFD code has been used to improve the noise attenuation of the above component through the introduction of a Helmholtz and a column resonator along the inflow pipe.
Both the base and the modified air box have been coupled to the engine, installed inside a vehicle. An experimental analysis has been carried out to measure the engine performance and the gasdynamic noise at the intake. Some comparisons have been then reported with the numerical results derived from a one-dimensional analysis of the whole engine. Finally, a time-step based, fully integrated 1D-3D analysis has been carried out to improve the accuracy of the numerical results.
