How Long is the Warranty for a Urea Pump?
1 Answers
Generally, the warranty period for a water pump is about one year. However, the warranty period for a pump is specifically stipulated in the contract by the manufacturer based on their product performance and bilateral negotiations. Principle of Automotive Urea: The main harmful substances in exhaust are nitrogen oxides and particulates. Technical measures can reduce particulate emissions within the engine, leaving mainly nitrogen oxides in the exhaust. Urea is injected into the exhaust after-treatment device, where it decomposes into ammonia at high temperatures. Under the action of a catalyst, the ammonia reacts with nitrogen oxides to produce harmless nitrogen and water. This device is called the SCR (Selective Catalytic Reduction) after-treatment system. Urea Consumption: Vehicles have a dedicated urea tank, and urea is consumed as long as the vehicle is running, so it needs to be replenished in time. Typically, about 4 liters of urea are consumed per 100 liters of diesel. The exact amount depends on factors such as engine displacement, model, manufacturer, etc. Different road conditions and load weights will also affect urea consumption.
