Internal Combustion Engines—Piston Rings—Vocabulary

1998-04-17
HISTORICAL
J1588_199804
Differences, where they exist, are shown in Appendix A with associated rationale. This SAE Standard defines the most commonly used terms for piston rings. These terms designate either types of piston rings or certain characteristics and phenomena of piston rings. The terms and definitions apply to piston rings for reciprocating internal combustion engines and compressors working under analogous conditions. Appendix B is included which lists equivalent terms in English, French, Russian, German, Spanish, Portuguese, Italian, and Japanese.

HISTORICAL
J1999_199804
Differences, where they exist, are shown in Appendix A. This SAE Standard specifies the essential dimensional features of N, NM, E, and EM scraper piston ring types. Dimensional Tables 7 and 8 offer the choice of two radial wall thicknesses: a Radial wall thickness "regular" (Table 7) b Radial wall thickness "D/22" (Table 8) The requirements of this document apply to scraper rings for reciprocating internal combustion piston engines up to and including 200 mm diameter. They may also be used for piston rings of compressors working under similar conditions.

HISTORICAL
J2002_199804
Differences, where they exist, are shown in Appendix A. This SAE Standard specifies the dimensional features of S, G, D, and DV oil control piston ring types. The normal range for the axial width of oil control rings (2.5 to 8 mm inclusive) is divided into 0.5 or 1.0 increments. In Table 7, dimensions in inch units are given for oil control rings with axial width 4.75 mm (equal to 3/16 in) for existing applications. The requirements of this document apply to oil control rings for reciprocating internal combustion piston engines up to and including 200 mm in diameter. They may also be used for piston rings of compressors working under similar conditions.

Internal Combustion Engines—Piston Rings—Half Keystone Rings

1998-04-01
HISTORICAL
J2001_199804
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.
