How Much AdBlue Should Be Added?
2 Answers
AdBlue usage is generally 3%-5% of diesel fuel consumption, meaning 3-5L of AdBlue solution is required for every 100L of diesel. Follow this ratio for proper refilling. Below are key details about AdBlue: 1. Purpose of AdBlue: Vehicles primarily use AdBlue to reduce exhaust emissions, as diesel engines emit nitrogen oxides (NOx) and particulate matter (PM). 2. National regulations: Due to the severe harm of vehicle emissions to human health and the environment, China's National IV emission standards (implemented in 2008) mandate that diesel vehicles' emission reduction systems must use AdBlue.
I've recently researched a lot about AdBlue usage and found that the refill amount depends on the specific vehicle model. Typically, the AdBlue tank capacity ranges between 10 to 20 liters – for instance, trucks may have larger tanks around 30 liters, while passenger cars might hold about 10 liters. The optimal refill timing is when the dashboard warning light illuminates; at this point, top it up until the tank is full. Avoid underfilling because the SCR system requires a stable supply to reduce emissions, but also don't overfill to prevent spillage. From my experience with diesel vehicles, I've learned that during refills, it's crucial to maintain AdBlue quality—choose certified OEM products to avoid contamination by impurities. Regular top-ups can prevent system errors or speed limitations. Safe driving is paramount, especially checking the fluid level before long-distance trips to save both hassle and costs.
