In an effort to meet tightening environmental regulations, pre-owned National V emission trucks have been made available. These trucks are equipped with advanced emission control systems including diesel particulate filters (DPF) and selective catalytic reduction (SCR) systems on diesel powered trucks. Shunzhao’s used national V emission trucks are ideal for cost-conscious businesses trying to meet environmental regulations. While older models are not as sophisticated, these trucks are impressively pre-owned. These are legally operable vehicles in the areas with strict air quality management policies without the risk of incurring heavy fines or severe restrictions. Provided that the emission control systems are functioning properly, of course. The routine maintenance required to stay under National V controls like DPF cleaning and SCR fluid refilling do require controlled emissions on the truck.
