The design principles for air intake systems (consisting of an air filter, intake manifold, resonators and air hoses) of passenger cars and the components themselves have changed in the past due to changes in customer requirements and legislation.
The intake system components, for the most part, are still developed as single parts, not as a common intake system. The interactions within the complete system, concerning gas dynamics, acoustics and other aspects, are often only considered in a late development stage.
To fulfill future demands, changes in the intake system development process and changes in intake system technology are necessary. This will be shown by examples.
