Combustion systems with swirl chambers are applied in some spark ignition engines with homogeneous mixture. Such systems are developed to burn lean mixture with increased compression ratio far from the knock limit [1,2]. It was shown that these systems could be significantly improved by employing a prechamber with a catalyst [3,4]. An important part of the discussed combustion systems is cylindrical combustion chamber with a strong swirl. In this chamber, the flame propagates in the field of centrifugal forces increasing with a radius. In such conditions the flame surface takes the form of a cylinder. In the past, in a few experimental studies the behavior of flame propagation was investigated under the action of increased centrifugal forces, but the results were qualitative in nature [5, 6 and 7]. In the proposed paper an experimental study of flame propagating in a mixture with rigid-body rotation was carried out.
