摘要

The arrangement has a spark plug (9) arranged in an outer side of a chimney, and a combustion chamber provided with an opening (12). Complementary anti-rotation units of the spark plug cooperate with anti-rotation units of a sliding cross member (14). The anti-rotation units of the sliding cross member comprise an annular projection part (19) that comprises a recess (20), where the projection part is arranged inside the sliding cross member. A longitudinal direction rib (21) extends on a part of length of the plug.
