The MT765J281AAU urea injector, as a core component of the diesel vehicle exhaust treatment system, precisely sprays urea solution to convert nitrogen oxides in the exhaust into nitrogen and water, playing a significant role in reducing air pollution.It can be specifically divided into the following major aspects:
1. Energy consumption
Although the single-time power consumption is low, combined with the huge number of diesel vehicles in the world, the long-term accumulated energy consumption cannot be ignored.
2. Carbon footprint of production and transportation of urea solution
The MT765J281AAU syringe needs to be used with urea solution, and the production of urea solution itself involves carbon emissions: industrial urea synthesis requires a high-temperature and high-pressure environment, which consumes a lot of energy; the filling and transportation of the solution require the use of plastic containers and transportation vehicles.
3. Dependence on SCR system efficiency
Ammonia, as an alkaline gas, will not only corrode the exhaust pipeline, but also react with acidic substances in the atmosphere to generate secondary particulate matter, exacerbating PM₂.₅ pollution and counteracting the original intention of exhaust gas purification.
4. Difficulties in recycling and disposal of discarded syringes
After the vehicle is scrapped, the discarded MT765J281AAU syringe may be randomly discarded or illegally dismantled if it is not included in the standardized recycling system: although the metal parts are recyclable, the heavy metals such as lead and mercury contained in the electronic components will seep into the soil and groundwater if not properly treated, causing long-term pollution; plastic parts are difficult to degrade naturally and can remain in the environment for hundreds of years, becoming a source of "white pollution".
