A new generation of State III diesel engine (hereinafter abbreviated as EGR engine) independently developed by Yangchai achieved an important breakthrough. The exhaust gas recirculation system passed the emission certification in Tianjin and has the conditions to upgrade the national IV standard.
In June 2008, after the official launch of the China III diesel engine, which was powered by CNHTC's fuel injection system and exhaust gas recirculation technology, the technology route attracted attention in the engine industry. Subsequently, major domestic engine companies started EGR R&D projects.
According to reports, Yangchai Company quickly carried out in-depth research and development on the flagship YZ4DB model, using Longkou Long Pump Fuel Injection's P8500 in-line pump, and equipped with Wuxi Longsheng Technology's EGR system to develop the State III in-line pump product. In December last year, Yangchai's first in-line pump plus EGR system engine, the YZ4DB2-30 engine, passed the State III emission certification in Tianjin. In March of this year, the Ministry of Industry and Information Technology of the People's Republic of China passed the record. At present, YZ4DA, YZ4DB, YZ4DD and other models have obtained relevant emission reports, and domestic related vehicle manufacturers are vigorously making announcements and development of related models.
