Abstract
The computational code KIVA-3V has been used as the modeling platform for Gasoline Direct Injection engine simulations. Improved models for fuel injection, wall impingement and stratified combustion have been implemented. To complement the modeling effort, experimental data of an optical engine at the University of Michigan has provided extensive data for validating the new models. The experimental data include Planar Laser Induced Fluorescence measurements, with toluene as a tracer, of the injection, mixing and combustion events in an optical engine. In this work, focus is given on the combustion model development and validation with experiments.
