Diesel engines exhaust much more NOx(Nitrogen Oxides) and PM(Particulate Matter) than gasoline engines, and it is not easy to reduce both NOx and PM simultaneously because of the trade-off relation between two components. This study investigated flame characteristics of the partial premixed compression ignition known as new combustion method which can reduce NOx and PM simultaneously. The investigation was performed through the analysis of the flame images taken by a high speed camera from the visible engine which is the modified single cylinder diesel engine.
The results obtained through this investigation are summarized as follows;
(1) The area of the luminous yellow flame was reduced due to the decrease of flame temperature and even distribution of temperature.
(2) The darkish yellow flame zone caused by the shortage of the remaining oxygen after the middle stage of combustion was considerably reduced.
(3) Since the ignition delay was shortened, the violent combustion did not occur and the combustion duration became shortened.
