How much urea does a China VI vehicle consume per 100 kilometers?
2 Answers
Under normal circumstances, the urea consumption of China VI vehicles is generally around 5~8L. Reasons for excessive urea consumption: 1. Substandard exhaust: If the nitrogen oxide sensor detects that the vehicle's exhaust does not meet standards, it will cause the nozzle to inject more urea, leading to increased urea consumption. 2. Poor fuel quality: This results in an increase in harmful gases in the exhaust, requiring the nozzle to inject more urea for oxidation-reduction reactions, thereby increasing urea consumption. 3. Poor urea quality: This necessitates more urea for oxidation-reduction reactions, leading to higher urea consumption. 4. Computer issues: The computer program board limits urea consumption. If there is a problem with the computer program, urea consumption may also increase. 5. Driving conditions: Long-term driving on undulating mountain roads can cause incomplete combustion of diesel in the engine, resulting in poorer exhaust quality and requiring more urea for oxidation.
To be honest, I'm the kind of person who really enjoys delving into automotive technology. For China VI vehicles, the urea consumption typically ranges from 0.5 to 1.0 liters per 100 kilometers. This range largely depends on the vehicle model and usage—for example, small diesel cars might consume as low as 0.5 liters, while SUVs or trucks can go up to 1 liter or more due to higher engine load. Urea (AdBlue) is used in the SCR system to treat exhaust emissions, designed to be both cost-effective and environmentally friendly. There are many influencing factors: driving habits—sudden acceleration or frequent braking increases fuel consumption, which in turn pushes up urea usage; temperature also plays a role, as the system is less efficient in cold winter weather, potentially leading to higher consumption. On average, urea consumption accounts for about 5% to 8% of fuel usage. I’ve recorded data from my own driving—my car consumes around 0.7 liters in city driving and only 0.5 liters on smooth highways. I recommend using genuine urea when refilling to avoid system blockages and unnecessary waste. In short, with proper maintenance, there shouldn’t be any major issues—it’s hassle-free, cost-saving, and keeps you compliant with regulations.
