Title:
燃焼機関における装置
Document Type and Number:
Japanese Patent JP2013530340
Kind Code:
A
Abstract:
In a combustion engine including a cylinder (11), a cylinder head (12), a cylinder head seal (16) and a scraper ring (17), an elastic scraper ring seal (23, 30) provided close to either or both end surfaces (20, 21) of the scraper ring 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 to improve the engine's efficiency, reduce emission values and lengthen the engine service life.
