How to Use Urea Solution in Vehicles?
2 Answers
Vehicles use urea primarily to reduce harmful nitrogen oxides in exhaust gases into nitrogen and water. It is generally used in diesel vehicles. There is a dedicated urea tank in the vehicle, where the urea solution is filled. As long as the vehicle is running, urea will be consumed, so it needs to be replenished in time. Typically, about 4 liters of urea is 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 can also affect urea consumption. Below is relevant information: 1. Introduction to vehicle urea: The scientific name of vehicle urea is Diesel Exhaust Fluid (DEF). It is commonly used in diesel engines as part of the SCR (Selective Catalytic Reduction) technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. Its composition is 32.5% high-purity urea and 67.5% deionized water. 2. Reason for adding urea in diesel engines: Since diesel engines emit polluting nitrogen oxide gases during operation, which are harmful to the atmosphere and human health, prolonged exposure to such gases can cause respiratory diseases. To mitigate the damage to the atmosphere and humans, when urea encounters nitrogen oxides emitted by diesel engines, a chemical reaction occurs, converting the nitrogen oxides into nitrogen and water for emission.
AdBlue fluid is crucial in diesel vehicles. As a DIY-loving car owner, I always check the AdBlue tank during refueling. Usually, there's a small blue-cap opening near the driver's seat or rear – just pour dedicated solution cans directly in (never confuse it with the fuel tank!). I recommend topping up every 5,000 km or so. The system alerts with a warning light when levels drop. If empty, the car starts but loses power, especially problematic for long trips. Standard AdBlue jerrycans are available in stores – use a funnel to avoid spills. In cold climates, opt for winter-grade antifreeze versions to prevent freezing blockages. Overall, it benefits vehicle emissions control by reducing exhaust pollution.
