抄録

An experimental study has been carried out to investigate the effects of supercharging on diesel spray dynamics and combustion characteristics. A rapid compression and expansion machine has been developed to reproduce diesel sprays and combustion. A copper vapor laser is used as a light source to visualize the spray. By synchronizing the laser output to a high speed 16 mm camera, instantaneous photographs of the spray can be taken. It is shown that supercharging can increase air entrainment in the spray and its evaporation. As a result, ignition lag can be reduced while the early part of diffusion combustion is increased.
