Recently, Dongfanghong lr4a off-road diesel engine completed the Euro V emission certification test in Jinan automobile testing center, and Dongfanghong diesel engine V diesel engine officially entered the stage of mass production. This indicates that Dongfanghong non road diesel engine has reached an advanced level in emission technology and emission control capacity.

The Dongfanghong lr4a Euro V diesel engine that passed the certification test is independently developed by China Yituo diesel engine company and the technology center, with completely independent intellectual property rights. Dongfanghong lr4a Euro V diesel engine adopts high-pressure common rail + supercharged intercooling + EGR + doc + DPF + SCR + ASC line, with power covering 80 ~ 150 HP, and its technology and performance have reached the international advanced level. TUV witnessed the strict of engineers in Rhine, Germany

Fanghong lr4a diesel engine easily completed a series of strict tests such as steady-state, transient and non-standard cycle tests, NCD / PCD related to EGR, DPF and SCR systems, so the urea thawing test at minus 18 ℃ successfully passed the non road Euro V emission certification test.

It is reported that the Euro V emission regulations for off-road diesel engines are the most stringent off-road diesel exhaust emission regulations in the world, which will be gradually enforced in EU member states according to the power range from January 1. In addition to more stringent requirements for diesel engine emission technology and post emission, the non road Euro V emission standard also further tightens the emission requirements for nitrogen oxides (NOx) and inhalable suspended particles (PN).

The structure and control logic of luou V diesel engine are more complex and the research and development is more difficult, which is a test for the enterprise's design, research and development level and production and manufacturing.

As a responsible enterprise, China Yituo has actively responded to the call of the country to win the blue sky defense war and made efforts for product upgrading and R & D. the R & D of the four products of Dongfang Hongfei road has always maintained an industry-leading trend. As early as 2015, China Yituo took the lead in the research and development of non road country 4 diesel engine. At present, China first tractor has successfully completed more than 70 calibration tests such as bench performance, complete machine power performance test, field calibration, PEMs test and plateau, high cold and high temperature. More than 50 machines have been verified in four fields in Henan, Jiangsu, Hainan, northeast and Xinjiang, with a cumulative operation time of more than 20000 hours and a maximum single machine operation of 3000 hours, The comprehensive performance of our four diesel engines has been fully verified. Thanks to the profound technical accumulation of the diesel engine company and the successful experience of Dongfang Hongguo IV product development, the R & D process of Euro V diesel engine was very smooth, and passed the emission certification test 3 months ahead of the original plan.

At present, the tractor equipped with Dongfanghong Euro V diesel engine has completed the sample, and the whole machine certification test will be carried out. Next, the company will orderly promote the certification of Dongfanghong 50 ~ 70 HP and 15 non road Euro V diesel engines as planned, and continue to build the best green power in China's agricultural machinery industry.
