This marks that DFH diesel engine has completed the development of non-road Euro 5 (ⅴ) diesel engine and entered the batch production stage, but also marks that the emission control technology of DFH non-road diesel engine has reached the world's most advanced technology level.
The Euro V (ⅴ) emission Regulation for non-road diesel engines is currently the most stringent emission regulation for non-road diesel engines in the world. It will be phased in by power segment in eu member States from 1 January 2019.
DFH LR4A Euro 5 (ⅴ) diesel engine adopts the technical route of high pressure common rail + supercharged intercooling +EGR+DOC+DPF+SCR+ASC, compared with non-road country four products, non-road Euro 5 (ⅴ) diesel engine structure and control logic is more complex, more difficult to develop.
This time, under the strict supervision of TUV Rhein witness engineers, DonghongLR4A diesel engine successfully completed steady-state, transient and non-standard cycle tests, completed THE NCD/PCD fault detection related to EGR, DPF and SCR systems, and carried out urea thawing test at minus 18℃.Finally, the non-road Euro 5 (ⅴ) emission certification test was successfully completed.
Yituo (Luoyang) Diesel Engine Co., Ltd. always pays attention to basic technology research.In 2015 took the lead in the industry on the road of four diesel engine research and development, has now completed the rig performance, the machine power performance test, field calibration and test of PEMS adaptability and plateau, cold, heat, and so on more than 70 calibration test, and in the northeast China, xinjiang, henan, jiangsu, hainan, region into four field validation machine more than 50 countries,The total operation time is more than 20,000 hours, and the longest single operation is up to 3,000 hours, which fully verifies the comprehensive performance of the non-road Diesel engine no.4.
Dongfanghong LR4A non-road Euro 5 (ⅴ) diesel engine is developed on the basis of non-road Country iv diesel engine. The power covers 80 ~ 150 HP and the torque reserve is up to 30%.Subsequently, Yituo (Luoyang) Diesel Engine Co., Ltd. will develop 50 ~ 70 HP and 150 ~ 300 HP non-road EURO 5 (ⅴ) diesel engines to provide the best green power for the oems.
