Abstract: The dynamic phenomena which occur in the intake manifolds of reciprocating internal combustion engines can be employed to manipulate their performance characteristic. It is possible to accurately predict the manifold flow using non-linear techniques but these are often too cumbersome for use at the initial design stage. The present work describes a computationally efficient linear technique with the facility to predict volumetric efficiency trends as a function of manifold geometry and which therefore has the potential to be used in the synthesis of new manifolds.

Keywords: intake manifold design; interference effects; linearised conservation equations; manifold resonance characteristics; manifold synthesis techniques; pipe ends; simulation; modelling; volumetric efficiency; vehicle design.
