Construction machinery will implement national IV emission standards by 2020

On August 19, 2018, the Ministry of Ecology and Environment issued Document No. 34 of 2018 on the announcement of the “Technical Policy for Pollution Prevention and Control of Non-Road Mobile Machinery” (hereinafter referred to as “Technical Policy”). The “Technical Policy” puts forward control targets for the newly produced non-road mobile machinery in the next 5-10 years, and stipulates that since January 1, 2020, off-road mobile machinery that does not meet the requirements of this standard and the installed diesel engine shall not be produced, imported, sold or put into use. According to different types of machinery, they are reflected in three aspects:

First, for non-road mobile machinery powered by compression-ignition engines (such as diesel engines), the control target is to reach the national fourth-stage emission control level by 2020, and to be connected with the world’s most advanced emission control level in 2025.

The second is the non-road mobile machinery powered by small-ignition engines (commonly known as small-sized machines, small gasoline engines and gas-fueled engines). The control targets are required to reach the national third-stage emission control level around 2020, and the world’s most advanced in 2025. Emission control levels are in line.

The third is for non-road mobile machinery powered by large-ignition engines (gasoline engines and gas-fueled engines). The control target is required to be in line with the world’s most advanced emission control level in 2025.

According to the contents of the announcement, it is a foregone conclusion that the construction machinery industry will implement the national four emission standards in 2020. In addition to the implementation of the national four emission standards has basically settled, there is a detail that has attracted the attention of the industry. That is the announcement that the 2025 non-road mobile machinery is in line with the world’s most advanced emission control level.

In 2008, the United States implemented the non-road T4 transition standard. In 2011, the EU implemented its equivalent non-road Euro IIIB emission standards. In 2014, the United States and the European Union switched to the T4 final standard and the Euro IV standard respectively. The China National Standard to be implemented in China is equivalent to the EU’s Euro IIIB and the US T4 transition standard.
