The BJ1201004 urea injector is a core actuating component of the automotive SCR exhaust gas treatment system.Are there any benefits to upgrading it?Here is the analysis for you:
1. Improve injection accuracy and ensure emission compliance
The upgraded BJ1201004 urea injector is equipped with a high-precision electronic control module and adopts a closed-loop control strategy, which can collect engine speed, load, exhaust temperature and other parameters in real time, accurately calculate and control the urea injection volume, greatly optimize the flow linear deviation and consistency, strictly comply with industry inspection standards, and can increase the nitrogen oxide conversion rate to more than 98%, easily meeting the National VI and EU Stage Strict emission standards such as IV can effectively avoid problems such as excessive emissions, illuminated fault lights, and failed annual inspections caused by inaccurate injection, and ensure that vehicles are legal on the road.
2. Optimize atomization effect and improve denitrification efficiency
The upgraded atomizing nozzle design is used to optimize the spray cone angle and spray performance, atomizing the urea solution into uniform and fine droplets, greatly increasing the contact area with high-temperature exhaust gas, accelerating the pyrolysis and hydrolysis process of urea, allowing ammonia to fully react with nitrogen oxides, completely solving the problems of uneven atomization of traditional injectors, incomplete denitration caused by excessive droplets, and low catalyst utilization.
3. Prevent clogging and scaling, extending service life
Optimize the structure and material of the nozzle, using special alloy materials that are resistant to urea corrosion and high temperature, and add automatic evacuation and anti-crystallization designs.
4. Weather resistance upgrade to adapt to extreme working conditions
The core components are made of wide-temperature chips and sealing materials, which can adapt to extreme working environments of -40°C to 120°C.It also improves vibration resistance, pressure resistance and salt spray resistance, and can calmly cope with complex working conditions such as long-distance transportation, rugged road conditions, high temperature exposure, etc., avoid injector jamming and failure due to environmental factors, and adapt to various climates and usage scenarios.
5. Save energy and reduce consumption, reduce vehicle costs
With precise injection control and efficient atomization effect, the efficient use of urea solution can be achieved and the waste of urea caused by excessive injection can be avoided.
6. Original factory adaptation and compatibility, easy and efficient installation
It strictly follows the original technical specifications and size standards, accurately adapts to the SCR system of the corresponding vehicle model, and can directly replace the traditional urea injector without modifying the installation structure, adjusting ECU parameters or replacing related components, and is perfectly compatible with the vehicle's original control system.
