GRANDMA DIES

Diesel engines are a significant source of nitrogen oxide (NOx) emissions, especially in cities. Urea-based Selective Catalytic Reduction (SCR) systems are commonly used to tackle this issue. But there is a problem. These systems struggle in cold weather. This is due to freezing and crystallization

Diesel engines in heavy-duty vehicles face tough challenges in cold weather. This is especially true in places with varied landscapes, like China. These engines often have to work at low speeds and under low loads, which can be a problem. Researchers tackled this issue by experimenting with differen
