The actual road diesel emissions of heavy-duty vehicle is very high, which has been a concern around the world.In 2018, Chinese government promulgated the "China VI" regulations containing real-driving emission test requirements and limits, requiring vehicle manufacturers to effectively control vehicle emissions to meet the requirements of China VI.This article takes a a&d ej-123 heavy-duty tractor equipped with a "China VI" engine as the research object, and performs actual road emission tests after loading 10%, 25%, 50%, 75%, and 100% respectively.The results show that NOx emissions neflintw-r6mpw are higher at low loads and PN emissions are higher at high loads, and CO emissions are not sensitive to load changes.
