Abstract: The technologies for development of spark ignition direct injection (SIDI) engines still need further research in China. Advanced
spray laser diagnostics, three dimensional computational fluid dynamics (3-D CFD) modeling and the combustion diagnostics based on optical
engine play leading roles in the development of SIDI combustion systems. Among these technologies, advanced laser diagnostics is becoming
increasingly important, because through laser diagnostics one can realize visualization and quantitative measurements of in-cylinder processes,
which are essential for validation of CFD modeling and understanding the physical phenomena in the mixture formation and combustion
processes. This paper summarizes and compares various technologies in spray laser diagnostics which are used to provide information
for modern SIDI combustion system development. The review includes diagnostics for spray structures, flow fields, droplet sizes and fuel
evaporation, which enables optimization and matching of the spray, air flow and the combustion chamber of an SIDI combustion system.

Key words: spark ignition direct injection (SIDI) engine, laser diagnostics, fuel spray, atomization and evaporation
