Where to Add Automotive Urea?
2 Answers
Automotive urea is filled into a dedicated urea storage tank, which is located near the fuel tank. Below is relevant information about automotive urea: 1. Reducing exhaust emissions: The primary reason for adding urea to diesel vehicles is to reduce exhaust emissions, as diesel engines primarily emit nitrogen oxides (NOx) and carbon particles. The main nitrogen oxide in diesel engines is nitric oxide (NO). High concentrations of NO can affect human pulmonary function and central nervous system function. Moreover, when released into the air, NO gradually converts into nitrogen dioxide (NO2), which has a strong irritating odor and can cause respiratory diseases. 2. China IV emission standards: Since nitrogen oxides can be catalytically reduced by ammonia from urea hydrolysis at high temperatures into harmless nitrogen and water, the China IV emission standards implemented in 2008 mandate the use of automotive urea in diesel vehicle emission reduction systems.
To be honest, I've seen the location for adding AdBlue quite a few times. It's that blue liquid used in diesel vehicles specifically for exhaust treatment. In your car's engine compartment, there's usually a small tank with a blue cap - that's the AdBlue filler port. The position varies by model: some are behind the headlights, some near the battery, or close to the air filter. Having driven several diesel models myself, I always look for that distinctive blue cap after popping the hood. Don't confuse it with the coolant or engine oil filler ports, as that could damage the system. The refill process is simple: turn off the engine, unscrew the blue cap, and pour in dedicated AdBlue fluid. I recommend checking the level during each service and topping up when low. Running empty might trigger warning lights or speed limitation, so don't neglect it. Remember, using proper AdBlue extends engine life and helps meet environmental standards.
