Abstract

In Low-Pressure Exhaust Gas Recirculation (LP-EGR), clean exhaust gas is extracted downstream of the after treatment, and reintroduced upstream of the turbocharger compressor. A major pathway for engine fuel economy improvement, by employing LP-EGR, is the enhancement of compressor and turbine efficiencies by increased flow rates which moves the operating points towards higher efficiencies. However, what is often overlooked in the literature is the influence of LP-EGR/air mixing flow field on the compressor performance. Here, we systematically study this effect on a turbocharger unit for a diesel engine on a hot gas stand using response surface methodology. In addition, the mixing flow field of LP-EGR and air upstream of the compressor was scanned using a 3-dimensional directional probe. A reconfigurable T-junction mixer geometry was used, enabling the study of major mixing parameters such as mixing length, and EGR introduction angle.
