Does Tuano need to add urea?
4 Answers
Tuano needs to add urea. Definition of automotive urea: It is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. The role of automotive urea is mainly to purify exhaust gases in vehicles. It can react with nitrogen oxides in the exhaust to reduce nitrogen oxide emissions. Automotive urea also optimizes engine performance and fuel consumption. Adding urea is to treat NOx nitrogen oxides in the exhaust. Without urea, the exhaust emissions cannot meet the standards. Automotive urea refill cycle: Automotive urea should be refilled approximately every 2,000 kilometers. For every 100 liters of diesel, 3 to 5 liters of urea are used. The usage of urea is equivalent to 3% to 5% of fuel consumption. When the urea level drops below 20%, it is necessary to promptly add automotive urea.
I've been driving the Tuya van for hauling goods at construction sites for several years. Diesel vehicles generally require urea because it's used to treat exhaust emissions. If you don't add it, the vehicle is prone to alarms, with warning lights appearing on the dashboard, and in severe cases, power may be limited, making it hard to drive fast. For light passenger vehicles like the Tuya, the frequency of urea refills is about every 5,000 kilometers. Just use standard AdBlue bottles; don't cut corners with inferior products to avoid clogging the system. While driving, always keep an eye on the urea tank's fluid level. If it's empty, go to a service station to refill it immediately—don't wait until you're stranded on the road. The maintenance cost isn't high, but neglecting this small matter can lead to big trouble, like suddenly slowing down on the highway, which is quite dangerous. Remember, during regular maintenance, ask the mechanic to check whether the urea pump and nozzle are functioning properly.
From a technical automotive perspective, the Tuano diesel engine comes standard with an SCR system, so urea addition is mandatory. The urea solution is converted into ammonia during exhaust treatment, reacting with nitrogen oxides to significantly reduce pollution. Without it, emissions will exceed standards, potentially triggering the vehicle's protective mode to limit output or even generating fault codes requiring a dealership reset. Based on my observation, average urea consumption is approximately 0.1 liters per 100 kilometers, with a dedicated refill port conveniently located next to the fuel tank for easy operation. Regular urea replenishment also extends engine life and reduces carbon buildup – it's advisable to use genuine products to prevent sensor interference from impurities. In summary, this isn't redundant but an essential maintenance procedure, as clearly stipulated in the owner's manual.
In my experience repairing vehicles, the Torvano diesel version must use urea. It is equipped with a urea system to comply with China VI emission standards. Not adding urea will trigger the level sensor alarm and engine restriction. I often advise owners to check the tank level every two to three months and refill it when empty, otherwise the system may lock up and affect the driving experience. The actual operation is simple and quick, taking only a few minutes with low cost. Remember to choose quality-compliant urea products and don’t go for cheap options.
