Optimal Design of the Intake System in 4-S I.C.E.

This article sets global rules for the design of the different elements of the intake system for a wide range of 4-s. i.c.e, examining the different phenomena related with the gas exchange process. With this objective, a broad analysis of a set of very different automotive engines was carried out, using a full wave action model developed by this same research group and widely checked by comparison with experimental results. The design criteria presented in the paper have been extensively and successfully applied in different development projects carried out for several automotive engine companies.
