润滑剂、工业用油及相关产品(L类).分类.第15部分:E系列(内燃机油)

[中文适用范围]： ISO 6743 的这一部分以表格形式建立了用于以下内燃机的发动机润滑油的详细分类： a) 采用曲轴箱扫气系统并用于运输的二冲程循环火花点火汽油发动机、休闲和实用应用，例如摩托车、雪地摩托、链锯（以下简称二冲程发动机油）； b) 四冲程火花点火汽油发动机，其采用通用油底壳，其中含有摩托车、小型摩托车、全地形车（ATV）和相关设备（以下简称）的发动机和传动系/起动机/变速箱的润滑剂称为四冲程发动机油）。 附件 A 中描述了舷外发动机和船用发动机的应用。 预计 ISO 6743 的这一部分应与 ISO 6743-99 [1] 一起阅读。 [外文原描述]： ISO 6743-15:2007 establishes the detailed classification, in tabular form, of engine lubricating oils for use in the following internal combustion engines: two-stroke cycle, spark-ignition gasoline engines that employ a crankcase scavenging system and are used in transportation, leisure and utility applications, such as motorcycles, snowmobiles, chainsaws (hereinafter referred to as two-stroke engine oils) and in four-stroke cycle, spark-ignition gasoline engines that employ a common sump containing the lubricant for both the engine and the drive train/starter/transmission of motorcycles, motor scooters, all-terrain vehicles (ATVs) and related equipment (hereinafter referred to as four-stroke engine oils). Outboard motor and marine engine applications are described. It is expected that ISO 6743-15:2007 be read in conjunction with ISO 6743-99.
