Abstract
Optical techniques play an important role in understanding the diesel spray and combustion to obtain high engine performance and low emissions. Combustion in a diesel engine is closely related to the transient injection of diesel spray into high pressure and temperature air. The air fuel mixing process, including atomisation and vaporization, is followed by the ignition and progressive, diffusive burning of the remaining regions. Diesel combustion is primarily controlled by the mixing process. The quality and distribution of fuel-air mixture are controlled by the characteristics of injection system, the nature of swirl and turbulence in cylinder, and spray characterization, such as spray tip penetration and drop diameter. Effective diagnostics of those phenomena are vital for an improved understanding on them thereby leading to a good control. This paper reviews optical techniques for diesel spray and combustion that were carried out in our laboratory. It starts with the three-dimensional visual measurements of diesel spray and combustion in optical engines. Then measurements of the diesel spray structure, such as spray tip penetration, drop size distribution and drop diameter are discussed. Finally, simultaneous measurements of vapour and liquid concentrations in an evaporating spray by five different optical techniques are introduced.
