The characteristics of AdBlue SCR Diesel Exhaust Fluid
AdBlue is a high-purity urea solution specifically designed for use in selective catalytic reduction (SCR) systems in diesel engines. Here are the key features of AdBlue:
High purity: AdBlue consists of 32.5% high purity synthetic urea and 67.5% deionized water. The high purity ensures that it does not form deposits or clogs in the SCR system.
Non-toxic and harmless: AdBlue is colorless, tasteless, non-toxic and harmless to the environment and human body. It's also easy to clean up in case of a spill.
Freezing point and storage: The freezing point of AdBlue is about -11°C. Measures should be taken to prevent ice formation in winter. The recommended storage temperature is between -5°C and 25°C, avoiding direct sunlight and extreme temperatures.
Stability: Under the right storage conditions, AdBlue can remain stable for a long time, with a general shelf life of one year.

Selective catalytic reduction (SCR) system is an effective technology to reduce nitrogen oxide (NOx) emissions in modern diesel engines, which is widely used in various diesel vehicles and equipment.
Commercial vehicles: including trucks, buses and vans. SCR systems help these vehicles meet stringent emission standards, such as Euro 6 in Europe and EPA Tier 4 in the United States.
Passenger cars: Some diesel passenger cars are also equipped with SCR systems to reduce emissions and improve fuel efficiency.
Non-road mobile machinery: such as construction equipment, agricultural machinery and ships, which usually use diesel engines, SCR technology is also suitable for these fields.
Regular AdBlue filling: Vehicles need to be regularly filled with AdBlue, generally through a dedicated filling port. The vehicle will have a warning system to remind the driver when it needs to refill.
System monitoring: Modern SCR systems are equipped with sensors and monitoring devices to ensure proper system operation. Once a fault is detected, the driver receives a warning.
By adopting SCR technology and using AdBlue, diesel engines can significantly reduce harmful emissions while maintaining efficient performance, playing a positive role in environmental protection and public health.
