Internal Combustion Engines--Piston Rings Coil Spring Loaded Oil Control Rings

2008-06-30

CURRENT

J2003_200806

This SAE Standard is equivalent to ISO Standard 6626. Differences, where they exist, are shown in the appendix with associated rationale. This document specifies the essential dimensions of piston ring types DSF-C, DSF-CNP, SSF, GSF, DSF, DSF-NG, and SSF-L coil spring loaded oil control rings. For the cast iron part the recommended material is class 10 according to SAE J1590. For special applications material classes 20 to 50 may be used. Variation in face design and spring groove from these may be used, as recommended by individual manufacturers, in plain or chromed versions. The tangential forces of coil spring loaded oil control rings can be varied over a wide range. Explanations and recommendations are given in Section 6. The normal range for axial width of coil spring loaded oil control rings (3 to 8 mm inclusive) is divided into 0.5 or 1.0 mm steps.

Power Cylinder Scuffing: Mechanisms

2020-08-12

CURRENT

J3070_202008

This document describes the various scuffing failure modes of the power cylinder system in an internal combustion engine. The causes and preventative measures for each failure mode are discussed. It should be noted that many remedies for scuff can lead to NVH (noise vibration and harshness) issues. However, NVH is not considered in this document.

INTERNAL COMBUSTION ENGINES—PISTON RINGS—EXPANDER/SEGMENT OIL CONTROL RINGS

HISTORICAL

J2004_199210

Differences, where they exist, are shown in Appendix A with associated rationale. This SAE Standard specifies the dimensional features of commonly used oil control rings having two steel segments (rails) separated and expanded by one steel expander/spacer. The segments vary in width from 0.4 to 0.6 mm. The assembly width ranges from 2.5 to 4.75 mm. The 4.75 mm width is equivalent to existing 3/16 in applications. Expander design will vary considerably with piston ring manufacturer. The total circumferential deflection and the piston groove depth should be considered when designing these oil rings to optimize the fit of the ring assembly into the piston groove. This document applies to oil control rings up through 125 mm for reciprocating internal combustion engines. It may also be used for piston rings of compressors working under similar conditions.

Internal Combustion Engines--Piston Rings--Half Keystone Rings

CURRENT

J2001_200806

This SAE Standard is equivalent to ISO Standard 6624/2 TR. Differences, where they exist, are shown in Appendix A. This SAE Standard specifies the essential dimensional features of HK- and HKB- half keystone rings with narrow ring width types. Dimensional and allow for the use of cast iron (Table 6) or steel (Table 7). Since the modulus of elasticity of steel rings is higher than that of cast iron rings, the fluctuation in the surface pressure will become greater if the free gap is set as the reference for forces. Therefore, forces are set using the surface pressure as the reference in order to minimize the effect of the fluctuation. The requirements of this document apply to half keystone rings of reciprocating internal combustion engines up to and including 70 mm diameter for cast iron rings and up to and including 100 mm diameter for steel rings.
