What is the difference between fake China IV and real China IV?

[Blanco]

Fake China IV trucks are not strictly China IV trucks. In reality, fake China IV trucks are equipped with engines below the China IV standard but have China IV certification procedures. Although the paperwork shows China IV, it is essentially 'selling dog meat as mutton.' 1. Reasons for the emergence of fake China IV: China IV trucks require the use of urea to reduce emissions, but for those who need to transport goods year-round, the cost of urea consumption is relatively high. 2. How to determine a truck's emission standard: You can judge by the engine's fuel supply method. Plunger pump fuel without turbocharging is China I emission standard, plunger pump fuel with turbocharging is China II emission standard, electronic injection with turbocharging is China III standard, electronic injection with turbocharging and exhaust treatment is China IV standard, and high-pressure common rail with exhaust treatment is China VI standard. 3. Ask the vehicle management office staff with the vehicle's registration certificate.
