This paper presents some experimental results of the characteristics of flames in a diesel engine using a constant volume combustion chamber in the wider range of initial pressure and temperature.
Taking high-speed photography, the characteristics of flames are classified into diffusion burning, premixed burning, luminous dots burning, premixed burning with luminous dots at the beginning and transient burning.
The boundaries of these types of burning have the close relation to the illumination delay that is dependent on initial pressure, initial temperature and oxygen concentration of the charge.
