What is the volume of the urea tank in liters?
3 Answers
20kg urea tank is 15 liters. Function of automotive urea: Automotive urea reduces nitrogen oxides in vehicle emissions, lowering the level of exhaust pollution. Automotive urea solution is a colorless, transparent, and clear liquid with a concentration between 31.8 and 33.2. Currently used automotive urea solutions are generally composed of 32.5% high-purity urea and 67.5% deionized water. Automotive urea solution is key to reducing pollutant emissions from diesel vehicles. It is a urea-based chemical reactant, made by mixing high-purity urea with deionized water, forming a 32.5% concentration solution. Applying automotive urea solution in the SCR (Selective Catalytic Reduction) system is crucial for achieving engine exhaust emissions that meet China IV and higher emission standards. Automotive urea: Automotive urea, also known as Diesel Exhaust Fluid (DEF), is essential for reducing nitrogen oxides in vehicle exhaust and lowering pollutant emissions from diesel vehicles. It is also a necessary consumable in SCR (Selective Catalytic Reduction) technology.
I've driven diesel vehicles for over a decade and am quite familiar with the urea tank. The capacity definitely isn't standardized—it varies significantly across different models. Generally speaking, passenger cars or SUVs have smaller tanks, typically around 10 to 15 liters, while heavier vehicles like pickups or construction equipment can go up to 20 or even 30 liters. My vehicle has a 20-liter tank, which lasts for two to three thousand kilometers on long trips before needing a refill—convenient and hassle-free. Why the variation? Designers have to balance space and emission requirements. A tank that's too small requires frequent top-ups, while one that's too large eats into cargo space. Maintenance-wise, it's crucial never to add other liquids, as this can cause system failures. I've made it a habit to check the urea level every time I refuel, topping it up in advance to avoid speed restrictions due to low levels. A well-sized tank ensures smoother driving and saves you the hassle and expense of emergency repairs.
From a technical enthusiast's perspective, I've been studying automotive systems for quite some time, and the design of urea tank capacity is truly an art. Manufacturers tailor it according to emission regulations, typically ranging between 10 to 30 liters, with passenger cars averaging around 20 liters. The size depends on the working pressure of the SCR system—for instance, high-efficiency engines require more urea to convert nitrogen oxides, making a larger tank more suitable. A tank that's too small leads to frequent stops for refills, affecting convenience; while one that's too large wastes space and adds weight, increasing fuel consumption. Having driven different vehicles, I've noticed that tank capacity relates to driving habits—rapid acceleration speeds up consumption, so a larger tank offers peace of mind. During maintenance, choosing qualified urea products is crucial to prevent nozzle clogging from impurities. I recommend checking the tank's status every 10,000 kilometers to ensure both environmental compliance and efficiency.
