How often should the urea filter be replaced?
1 Answers
The urea filter generally needs to be replaced every 50,000 to 60,000 kilometers. All vehicles with diesel engines require urea. Diesel engine vehicles have a urea nozzle in the exhaust pipe, which sprays a urea aqueous solution to purify the exhaust gas. Methods for cleaning the urea nozzle: 1. A small ultrasonic cleaner can be used for cleaning, with each cleaning session lasting no less than 15 minutes. During cleaning, functional tests can be performed to drive the nozzle, which improves the cleaning effect. 2. It can also be cleaned by soaking in warm water, with each session lasting no less than 15 minutes. Be careful not to immerse the plug in water.
