The engine (I) has an outer envelope (3) defining a peripheral annular space (4) along a side wall (5) of a fire tube (2) that allows flow of air from an air inlet of the engine. Parallel fixed flow guides (11-14) define flow channels in the space. Mobile pins (25) arranged in the space are connected to a mobile transversal base (18) of the tube. The pins block the channels to orient a part of air to an air-fuel detonating mixture intake port (20A) and liberate the channels when the base occupies two limit positions corresponding to chamber supply and mixture detonation phases, respectively. |
