Paper Abstract

Pseudo high speed photography has been developed to observe intermittent, periodic and high speed phenomena like diesel spray. Main device of this photography consists of Automatic Variable Retarder (AVR) which delays gradually timing between diesel injection and strobe spark with the micrometer. This technique enables us to observe diesel spray development just like images taken by a high speed video camera. This paper describes a principle of pseudo high speed photography, experimental results of adaptation to diesel spray and analysis of the diesel atomization mechanism.
