摘要：
An arrangement in combustion engines comprises a cylinder (11), a cylinder head (12), cylinder head seals (16) and a scraper ring (17). An elastic scraper ring seal (23, 30) is provided close to either or both of the end surfaces (20, 21) of the scraper ring and separates volumes formed close to the scraper ring from the combustion chamber. Separating these volumes from the combustion space prevents the accumulation of residues of incompletely burnt fuel in these volumes. This makes it possible to improve the engines efficiency, reduce emission values and lengthen the engines service life.
