In order to implement the "Environmental Protection Law of the People's Republic of China" and the "Law of the People's Republic of China on Prevention and Control of Atmospheric Pollution", this standard is formulated to prevent environmental pollution caused by pollutant emissions from diesel engines for non-road mobile machinery and to improve ambient air quality. This standard specifies the emission limits and measurement methods for the exhaust pollutants of diesel engines for non-road mobile machinery in the third stage, and proposes the fourth-stage predictive requirements. This standard is modified by the European Union (EU) Directive 97/68/EC (as of revision 2004/26/EC), “On the Law on Coordinating the Measures taken by Member States to Control the Emission of Gaseous Pollutants and Particulate Matter from Non-Road Mobile Machinery Engines†Technical content of diesel engines for non-road mobile machinery. Since October 1, 2014, all non-road mobile machinery diesel engines that have been approved for exhaust pollutant discharge type must meet the requirements of the third stage of this standard. Before the implementation date of the regulation, the application and approval of the type approval may be carried out in accordance with the corresponding requirements of this standard. For the non-road mobile machinery diesel engine approved according to this standard, the production consistency check shall be carried out from the date of approval. Since October 1, 2015, the second phase of non-road mobile machinery diesel engines will be discontinued. All manufactured and sold non-road mobile machinery diesel engines must meet the requirements of the third stage of this standard. Since April 1, 2016, the manufacture, import and sale of non-road mobile machinery equipped with second-stage diesel engines will be discontinued. All non-road mobile machinery manufactured, imported and sold shall be equipped with diesel engines complying with the requirements of the third stage of this standard. The new standard encourages qualified areas to implement this standard in advance.
