Abstract
Within a common project of Behr and Mann+Hummel a comparison between direct and indirect charge air cooling integrated in the intake manifold was carried out by vehicle measurements in the wind tunnel. In comparison with the series-production solution based on direct charge air cooling, a prototype intake module (intake manifold with integrated indirect charge air cooler) significantly reduced charge air pressure loss, provided a highly uniform temperature distribution in the runners, and reduced the charge air volume between the compressor and point of entry into the engine.
