Stationary Flame Front in a Swirl Combustion Chamber

Abstract

The combustion process, known as Texaco Combustion Process, eliminates the knock of a conventional gasoline engine by means of the swirling air and fuel injection. Furthermore, it enables the engine power to be controlled by variation of fuel quantity without air throttling. However, the existence of the stationary flame front, which contributes for the elimination of knock, is not yet confirmed. In this paper, the slow motion pictures of flame front in a combustion chamber with air-swirl were taken through the glass window. The result of the experiment reveals that a stationary flame front exists under a certain running condition.
