Claim:
1. An annular combustion chamber of a turbine engine, the annular combustion chamber comprising: an inner wall and an outer wall coaxial with the inner wall forming two surfaces of revolution connected together at upstream ends of the inner and outer walls by an annular chamber end wall comprising openings for mounting injection systems, each opening comprising an injector and at least one swirler for producing a rotating air stream that mixes downstream with fuel coming from the injector, and an ignition spark plug mounted in an orifice in the outer wall downstream from the injection systems, wherein the ignition spark plug is situated circumferentially between adjacent first and second injection systems that are configured to produce two air/fuel mixture sheets rotating in first and second directions, respectively, which are opposite each other, and wherein, in the annular combustion chamber, only the first injection system produces the air/fuel mixture sheet rotating in the first direction.
