Intake Manifold Design for an Air Restricted Engine

The purpose of this work was to study the effects that an air restriction has on basic intake manifold design calculations. When designing an intake manifold for a combustion engine, there are several simple methods that engineers have used historically to help determine peak volumetric efficiency per engine rpm. Methods such as Helmholtz Resonator Tuning and Pressure Wave Tuning have been used substantially to determine an engine’s operating conditions. However, these methods are flawed for the restricted engine case due to the assumption that there is an unlimited amount of air. Through experimentation of various intake manifold configurations, it is possible to determine how this false assumption affects the results of the design. Examination of each major design parameter of an intake manifold independently compared with the traditional analytical hypothesis is performed to help to determine if these methods can still be used in an air restricted environment. Based on the results from this experimentation, it appears that these calculations can still determine where peak volumetric efficiency is. However, the area around the peak volumetric efficiency is affected significantly.
