Abstract [en]

The distribution of EGR between the cylinders of an internal combustion engine has been shown to have large impact on the engine emissions. Especially at high EGR, the combustion reacts sensibly to variations in the EGR-rate. A cylinder that receives excessive EGR produces soot emissions while a cylinder with too little EGR has increased NO<inf>X</inf>-formation. It is therefore important to have knowledge about the mixing of air and EGR in an engine. This study compares two different EGR-mixing measurement methods. The first is based on CO<inf>2</inf> measurement with standard probes, placed at 36 different locations in the intake manifold of the engine. The second method uses a laser beam and a detector to gain information about the mixing with a high time-resolution. Additionally, 1-D simulations are used to gain information about the mixing process. To vary the mixing process on the engine, two different air/EGR mixers are used and their mixing performance is evaluated.
