Does China IV require urea addition?
2 Answers
China IV definitely requires urea addition. Introduction to automotive urea: Automotive urea is generally used in heavy-duty trucks and plays a crucial role in upgrading to China IV emissions. Due to factors such as China's national conditions and fuel quality, the mainstream approach for upgrading to China IV is the SCR technology. However, this technology requires the addition of automotive urea to meet the China IV emission standards. Function of automotive urea: The primary purpose of adding automotive urea to China IV emission vehicles is to reduce nitrogen oxide emissions, thereby achieving environmental protection goals. China's approach to upgrading to China IV is the SCR route, which employs selective catalytic reduction technology.
Driving a China IV diesel vehicle definitely requires adding urea. I've been driving this type of vehicle for several years. The China IV emission standards require strict pollution control, so the vehicle is equipped with a urea injection system to clean the exhaust. If you don't add urea, the system will detect it and turn on the fault light, and it may even limit the vehicle speed or report errors, affecting safety. I usually check the urea level every 3,000 to 4,000 kilometers and buy special urea at gas stations or repair shops to refill the tank. During maintenance, pay attention to the nozzle to avoid clogging—keeping it clean ensures normal operation. Before long-distance trips, always check to avoid problems on the road. Once you get into the habit, it's not difficult. The key is to operate on time to ensure emissions compliance, smooth performance, and worry-free safety.
