Diesel Combustion Flame and Temperature Observation Using a Bore Scope Under the Conditions of High Boost, Wide Range and High Rate EGR
Published May 23, 2012 by Society of Automotive Engineers of Japan in Japan
Combinations of High Boost, Wide Range and High Rate EGR reduces exhaust emissions from diesel engines because of cylinder temperature reduction and preservation of excess air ratio. In order to reduce exhaust emissions and fuel consumption, it is important to measure the flame temperature and KL factor which are obtained by 2-color method in the diesel combustion. The diesel flame was directly and consecutively observed from the actual engine by means of a bore scope combined with a high-speed camera and analyzed by 2-color method as well.
