Gasoline Direct Injection (GDI) technology has been recognized as an effective way to achieve better engine performance and reduced pollutant emissions. High-pressure injectors are demonstrating many advantages in the applications for GDI engines providing a better fuel atomization, a better mixing with the air, a consequent more efficient combustion and, finally, reduced tailpipe emissions. In this context the present work features a dual experimental-numerical characterization of the jet issued from a multi-hole injector. The numerical model has been developed by means of a Eulerian-Lagrangian CFD code and validated thanks to experimental data collected with schlieren and Mie scattering imaging techniques.

Abstract

Gasoline Direct Injection (GDI) technology has been recognized as an effective way to achieve better engine performance and reduced pollutant emissions. High-pressure injectors are demonstrating many advantages in the applications for GDI engines providing a better fuel atomization, a better mixing with the air, a consequent more efficient combustion and, finally, reduced tailpipe emissions. In this context the present work features a dual experimental-numerical characterization of the jet issued from a multi-hole injector. The numerical model has been developed by means of a Eulerian-Lagrangian CFD code and validated thanks to experimental data collected with schlieren and Mie scattering imaging techniques.
