What are the methods for exhaust treatment of National III diesel vehicles?

You can appropriately increase the fuel injection quantity and use a cleaning agent added to the fuel to significantly reduce the smoke opacity value. Component inspection: If the power at the wheels meets the standard but the emission values do not comply, this situation is relatively easier to resolve. You can try adding cleaning agents such as smoke eliminators or repair agents to the lubricating oil. If the diesel vehicle's emission values are severely exceeded, it is necessary to check whether the fuel injectors or cylinders are severely worn or have carbon deposits, and they need to be cleaned or replaced promptly. Fuel selection: Diesel vehicle owners should also be careful not to use low-quality gasoline. Additionally, they should check whether the three-way catalytic converter on the vehicle is damaged. Owners should also pay attention to vehicle maintenance in daily life, as damaged parts during use can cause vehicle components to malfunction, leading to unqualified exhaust emissions.
