1 Answers
Gasoline vehicles sold between July 1, 2010, and December 31, 2017, are basically National IV standard. The relevant introduction about National IV standard is as follows: Introduction to National IV Emission Standard: Starting from May 1, 2018, the application for National III products was stopped, and only applications for National IV products were accepted. After July 1, 2018, no announcements for National III vehicle models were issued. When applying for the announcement of National IV vehicle models, new specifications and models should be used to distinguish them from National III vehicle models. Since the technical route has been specified in the new standard, National IV vehicle models no longer provide separate recommended technical solutions, and the standard requirements shall prevail. National IV Emission Standard Applicable Vehicle Models: Motorcycles and mopeds are classified according to maximum design speed and displacement. Among them, motorcycles refer to those powered by spark-ignition engines with a maximum design speed greater than 50 km/h or a displacement greater than 50 mL, as well as those powered by compression-ignition (diesel) engines with a maximum design speed greater than 50 km/h or a displacement greater than 50 mL for three-wheeled motorcycles.
