Analysis on the Development Status of my country's Diesel Engine Industry
In the environment of energy saving and emission reduction, not only the emission standards for family cars are becoming more and more stringent, but the emissions for non-road mobile mechanical vehicles are also increasing. As we all know, with the more and more extensive application of various types of non-road mobile machinery in production and life, the need for pollutant emission control is becoming more and more urgent. According to statistics, about 2 million non-road diesel engines are newly added every year in China, and about 20% of the national annual diesel consumption of more than 100 million tons is used for various types of non-road mobile machinery. These non-road mobile machines are important emission sources of nitrogen oxides, and it is estimated that the annual emission of nitrogen oxides is more than 2 million tons.
According to the "Notice on Limits and Measurement Methods of Exhaust Pollutants from Diesel Engines for Non-Road Mobile Machinery (China's Third and Fourth Stages)" issued by the Ministry of Environmental Protection on May 16, 2014: From October 1, 2015, the Manufacture and sale of diesel engines for non-road mobile machinery in the second stage. All manufactured and sold diesel engines for non-road mobile machinery must meet the requirements of the third stage of the above standards; from April 1, 2016, it will be stopped Manufacture, import and sale of non-road mobile machinery equipped with the second stage diesel engine. All non-road mobile machinery manufactured, imported and sold shall be equipped with diesel engines that meet the requirements of the third stage of this standard.
