Diffusive Combustion of Fuel Spray in a DI Gasoline Engine 2001-01-2524

The direct-injection gasoline engine (DIGE) is a new kind of ICE. How to compute and visualize the combustion is a new issue. This paper presents a new method to compute and visualize diffusive combustion in a DIGE. This method is based on a three-dimensional staggered grid. A zero-dimensional combustion model with sequential multi-point combustion is used for the elements of the fuel spray. The transient flow and pressure field caused by combustion may be determined by calculating the combustion processes of multi-points. This paper takes the DIGE as the studying example, calculating and visualizing the combustion process.
