Application Driven by the need for more cleaner, environment friendly vehicles to abide by stricter government regulations, it is imperative for automakers worldwide to make cars more fuel efficient and less polluting. Auto companies are forced to embrace the concept of "downsizing" building increasingly small, compact, yet powerful engines.

Technology has taken giant strides in the last 10 years in making GDI technology better and efficient, however there is still a large scope for further improvement. Not everything is understood and decoded as to what actually happens inside the GDI based combustion process, eluding the goal of achieving complete control over the successive events inside the combustion chamber.

Progress in GDI technology is at an advanced state with injectors from companies like Bosch, Continental , Delphi , Denso, etc, designing for worldwide use for different fuel qualities.

The meshing requirements of these tiny yet complex configurations are quite unique and challenging. The configuration demands a fine mesh with sizes going down to a few microns, to resolve the geometry and the associated flow physics. Researchers usually make use of Cartesian and Structured multi-block grids to discretize the flow domain. While Cartesian grids help in quickly generating unit aspect ratio mesh in no time, structured grids come in handy in generating optimized high aspect ratio grids. CFD will continue to play a pivotal role in designing cleaner and more fuel efficient engines.

GridPro, has automated the meshing for fuel injectors needle motions. To read more click here.
