标准摘要
[中文适用范围]： 本部分ISO 3046建立了调速系统要求和参数的分类，并规定了往复式内燃机（RIC）典型发动机转速的术语和定义。在必要时，针对特定发动机应用给出了个别要求。本部分适用于陆地、铁路牵引和船舶用的RIC发动机，不包括用于推进道路施工和土方机械、农业和工业拖拉机、道路车辆及飞机的发动机。此外，还排除了自调速发动机以及仅需最大速度或最大燃油输送限制的发动机。本部分定义了压燃式燃油发动机（柴油发动机）的要求。对于火花点火发动机和双燃料发动机，可适用特殊要求。注1：应用于RIC发动机驱动发电机组的调速系统的性能和参数在ISO 8528-2和ISO 8528-5中规定。注2：与超速保护装置相关的典型发动机转速的术语和定义在ISO 3046-6中规定。 [外文原描述]： ISO 3046-4:2009 establishes a classification for the requirements and parameters of speed-governing systems and specifies terms and definitions of typical engine speeds for reciprocating internal combustion (RIC) engines. Where necessary, individual requirements are given for particular engine applications. ISO 3046-4:2009 applies to RIC engines for land, rail-traction and marine use, excluding engines used to propel road-construction and earth-moving machines, agricultural and industrial types of tractors, road vehicles and aircraft. Also excluded are self-governing engines and those engines requiring only maximum speed or maximum fuel delivery limitation. ISO 3046-4:2009 defines requirements for compression–ignition oil engines (diesel engines). For spark ignition engines and dual fuel engines, special requirements can apply.
