4、AF.JUN95Issued 1962-06Reaffirmed 1995-06Superseding J824 JAN86ENGINE ROTATION AND CYLINDER NUMBERINGForewordThis reaffirmed document has been changed only to reflect the new SAE Technical Standards Boardformat.1. ScopeThis SAE Standard was developed to provide a method for indicating the direction o

5、f engine rotationand numbering of engine cylinders. The document is intended for use in designing new engines to eliminatethe differences which presently exist in industry.2. ReferencesThere are no referenced publications specified herein.3. Standard RotationCounterclockwise rotation as viewed from

6、the principal output end. If power can bedelivered from either end, rotation shall be as viewed from the flywheel end.4. Opposite RotationClockwise rotation as viewed from the principal output end. If power can be deliveredfrom either end, rotation shall be as viewed from the flywheel end.5. Cylinde

7、r NumberingCylinders shall be numbered by either of two methods:1a. In single or multibank engines, number the cylinders in the sequence in which the connecting rods aremounted along the crankshaft beginning with the cylinder farthest from the principal output end.b. In multibank engines, number the

8、 cylinders in sequence in each bank, starting with the cylinderfarthest from the principal output end and designate right or left bank by suffix letters “R“ and “L.“EXAMPLE: 1R, 2R, and 1L, 2L.If the suffix letters “R“ and “L“ are inadequate, other letter designations may be used if properly defined

9、.6. Right- and Left-Hand DesignationCylinder bank and accessory locations are described as right or leftwhen engine is viewed from flywheel or principal output end.PREPARED BY THE SAE POWERPLANT FORUM COMMITTEE1. This numbering method will generally exclude radial engines or those with coplanar cyli
