This project deals with the problem of improving the volumetric efficiency of a single cylinder engine (and with the possibility to extend it to multicylinder engine) for a wide range of frequencies. The reason for this project is that the acoustic phenomena which takes place inside an intake system greatly influence the volumetric efficiency of an engine. The studied solution is the addition of tunable resonators to the intake system. In order to obtain satisfactory results are treated the next configurations: an in-series resonator with a variable volume placed near the cylinder and a side-branch resonator with a variable cross section connected to a constant volume resonator. Intake systems equipped with this kind of resonators are studied using the Mathematica program.
