Yuchai YCK08 Guoliu Engine successfully completed the 1460 hour emission durability test and emission certification at Tianjin (China) Automotive Technology Research Center, becoming the first national six-heavy duty diesel engine to complete all type inspection projects, marking the YCK08 emission announcement certification work. Successful completion. A year ago, YCK08 successfully passed the most stringent national 6b certification, becoming the first national six heavy-duty diesel engine to obtain environmental information disclosure. According to the requirements, the engine still needs to carry out the discharge durability test, which requires the engine to be completed within one year of obtaining the environmental information disclosure. As one of the emission inspection type certification inspection items, the main purpose of emission durability is to determine the deterioration coefficient of the engine aftertreatment system through test verification to ensure that the discharge durability meets the requirements of the national six emission regulations. Therefore, Yuchai began the bench durability test in early June this year after a series of preparatory work including engine technology, prototype production, engine performance emission confirmation, and emission test certification before durability test. During the entire durability test, the engine did not show any faults, and five emission test certifications including start and end were completed, all meeting the emission limit requirements. This certification test shows that the YCK08 engine has fully met the emission regulations in terms of emission index achievement and durability guarantee. This is the best test for the quality of Yuchai engine, and it is Yuchai's management idea of ​​"green development and harmonious win-win". Best practice of action. Up to now, YCK08 has been equipped with Dongfeng Liuqi, Dongfeng Commercial, Shaanxi Automobile Commercial Vehicle, Zhengzhou Yutong, Xiamen Jinlong, Suzhou Jinlong and other OEMs, covering tractors, trucks, engineering vehicles, buses, and highway buses. And many other models. Ningbo Huacheng Rubber And Plastic Machinery Co., Ltd , https://www.hacen-machinery.com
