China YTO IR4A off-road diesel engine has passed the Euro 5 (V) emission certification test

Recently, China Yituo Dongfanghong lr4a off-road diesel engine completed the Euro 5 (V) emission certification test in Jinan automobile testing center.
This indicates that Dongfanghong diesel engine has completed the development of non road Euro 5 (V) diesel engine and entered the batch production stage. At the same time, it also indicates that the emission control technology of Dongfanghong non road diesel engine has reached the most cutting-edge scientific and technological level in the world.
Euro 5 (V) emission regulation of off-road diesel engine is the most stringent off-road diesel engine exhaust emission regulation in the world. It will be gradually enforced in EU member states according to power range from January 1, 2019.
Dongfanghong 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 4 products, the structure and control logic of non road Euro 5 (V) diesel engine are more complex and more difficult to develop.
This time, under the strict supervision of TUV eyewitness engineers in Rhine, Germany, Dongfanghong lr4a diesel engine successfully completed the steady-state, transient and non-standard cycle tests, completed the NCD / PCD fault detection related to EGR, DPF and SCR systems, conducted the urea thawing test at minus 18 ℃, and finally successfully completed the non Road Euro 5 (V) emission certification test.
YITUO (Luoyang) Diesel Engine Co., Ltd. has always paid attention to basic technology research. As early as 2015, it took the lead in the research and development of non Road National four diesel engines in the industry. At present, it has completed more than 70 calibration tests such as bench performance, overall power performance test, field adaptability calibration, PEMs test, plateau, high cold and high temperature, and invested more than 50 national four field verification machines in Henan, Jiangsu, Hainan, northeast, Xinjiang and other regions, with a cumulative operation time of more than 20000 hours and a maximum single machine operation of 3000 hours, The comprehensive performance of the non road country 4 diesel engine is fully verified.
Dongfanghong lr4a off-road Euro 5 (V) diesel engine is upgraded and developed on the basis of off-road country 4 diesel engine, with power covering 80 ~ 150 HP and torque reserve up to 30%. Subsequently, Yituo (Luoyang) Diesel Engine Co., Ltd. will develop 50 ~ 70 HP and 150 ~ 300 Mali non road Euro 5 (V) diesel engines to provide the best green power for each main engine plant.
