Edition date: 1990-12-13
In Force
Available languages: English, French
Summary:

This document specifies methods of designating the direction of rotation and the cylinders of reciprocating internal combustion engines and of designating a specific valve in a cylinder head when the cylinder head is mounted on the engine or dismantled. It defines right-hand and left-hand in-line reciprocating internal combustion engines and locations on a reciprocating internal combustion engine so that the position of equipment on the engine can be described. It applies to reciprocating internal combustion engines for land, rail-traction and marine use, excluding engines used to propel agricultural tractors, road vehicles and aircraft. It may by applied to engines used to propel road-construction and earth-moving machines, industrial trucks and for other applications where no suitable International Standard for these engines exists. 



La présente Norme internationale prescrit des méthodes de désignation du sens de rotation et des cylindres des moteurs alternatifs à combustion interne ainsi qu'une méthode de désignation d'une soupape donnée dans une culasse lorsque celle-ci est montée sur un moteur ou démontée. Elle donne la définition des moteurs alternatifs à combustion interne en ligne, à droite et à gauche, et définit les emplacements sur un moteur alternatif à combustion interne de façon à permettre l'indication de la position des équipements sur ce moteur. Elle est applicable aux moteurs alternatifs à combustion interne à usages terrestre, ferroviaire et maritime mais ne concerne pas les moteurs de tracteurs agricoles, de véhicules routiers et d'aéronefs. Elle peut être applicable aux moteurs de propulsion des engins de travaux publics et de terrassement, des chariots de manutention, ainsi qu'à tout autre domaine s'il n'existe aucune Norme internationale appropriée.
