Paper Abstract

Two optical methods, used for diesel engine combustion analysis under realistic conditions are presented, the relatively new technique, namely endoscopic high speed photography and flame pyrometry. Their basic feature is optical access to the combustion chamber achieved through small sized windows (dia. 10 mm), fitted into the cylinder head of the engine. The outcoming image from the endoscope is transmitted to the camera through several rigid optical relay systems, interconnected with rotating optical joints. A flash bulb located behind a second window is used to illuminate the nonluminious process of fuel spray formation during the ignition delay period.
