Internal combustion engines. Piston rings - Coil-spring-loaded oil control rings of narrow width made of cast iron Ingestion-build-181247 BS EN 2070-4 guidelines help1 Scope This part of ISO 6626 specifies the essential dimensional features of coil spring loaded oil control rings made of cast iron, types DSF C, SSF, GSF, DSF, SSF L, DSF NG and DSF CNP. It is applicable to those piston rings in sizes 60 mm to 110 mm, inclusive, for reciprocating internal combustion engines for road vehicles and other applications.
