Various combinations of engineload and speed reflect different engine applications (see ISO 8178-4).This part of ISO 8178 is applicable to RIC engines for mobile, transportable and stationary use, excludingengines for motor vehicles primarily designed for road use. This part of ISO 8178 may be applied to enginesused, for example, for earth-moving machines, generating sets and for other applications.In limited instances, the engine can be tested on the test bed in accordance with ISO 8178-2, the field testdocument. This can only occur with the agreement of the parties involved. It should be recognized that dataobtained under these circumstances may not agree completely with previous or future data obtained under theauspices of this part of ISO 8178. Therefore, it is recommended that this option be exercised only withengines built in very limited quantities such as very large marine or generating set engines.For engines used in machinery covered by additional requirements (e.g. occupational health and safetyregulations, regulations for powerplants), additional test conditions and special evaluation methods may apply.Where it is not possible to use a test bed or where information is required on the actual emissions producedby an in-service engine, the site test procedures and calculation methods specified in ISO 8178-2 areappropriate.【中国标准分类号】: J90;Z64【国际标准分类号】: 13_040_50;27_020【页数】: 124P;A4【正文语种】: 英语 | 欢迎光临 世界资料网论坛 (http://bbs.infoeach.com/) | Powered by Discuz!
