Adblue is used instead of 100% Urea because it is a more efficient and cost-effective solution for reducing harmful emissions from diesel engines. Adblue is a mixture of 32.5% high-purity synthetic urea and 67.5% deionized water, which makes it easier to handle and store compared to pure urea.
Adblue is injected into the exhaust stream of diesel engines, where it breaks down into ammonia. The ammonia then reacts with the harmful nitrogen oxides (NOx) in the exhaust gas, converting them into harmless nitrogen and water vapor. This process helps reduce emissions of nitrogen oxides, which contribute to air pollution and smog.
While pure urea can also be used for reducing emissions, it is not as effective as Adblue. The mixture of urea and water in Adblue allows for a more controlled and precise injection into the exhaust stream, resulting in better conversion of nitrogen oxides.
Yes, Adblue is safe to use. It is non-toxic, non-flammable, and biodegradable. However, it is important to handle it with care and follow proper storage and handling guidelines to avoid any potential hazards.
No, not all diesel engines require Adblue. Adblue is only necessary for diesel engines that are equipped with selective catalytic reduction (SCR) systems, which are designed to reduce emissions. However, many modern diesel vehicles and trucks are now equipped with SCR systems, making Adblue a common and necessary component for reducing emissions.
