The 0444043009 urea injector, as a core actuating component of the SCR after-treatment system for diesel vehicles, is mainly compatible with diesel vehicles and Marine diesel engines that meet Euro IV, Euro V and National VI emission standards.Its core function is to precisely inject urea solution and assist in exhaust gas purification, which is in line with the current green transformation and environmental protection policy requirements in the clean energy field.Its core applications revolve around the core demands such as exhaust gas treatment, system protection, and compliant operation, taking into account both practicality and environmental friendliness, and adapting to multiple application scenarios, providing support for the compliant and efficient operation of diesel equipment.
1. Adapt to compliance standards to ensure legal driving on the road
-Specifically matched to strict emission standards such as Euro IV, Euro V and National VI, it can meet the emission compliance requirements of different scenarios such as cars and ships.It helps vehicles and ships pass exhaust gas inspections and eliminates problems such as OBD alarms, torque limits and speed limits, inability to get license plates or failed annual inspections due to excessive NOx emissions.It ensures the legal and compliant operation of equipment and adapts to the emission control needs of diesel equipment under current environmental protection policies.
2. Precise control and adjustment to adapt to changes in working conditions
-It can receive data such as engine speed, fuel injection volume, and exhaust gas concentration from the ECU in real time.It uses a closed-loop control mode to dynamically adjust the urea injection volume, injection timing, and injection pressure (adapted to 40-160bar conventional working pressure) to ensure that the injection volume accurately matches the NOx concentration in the exhaust gas.This not only avoids excessive emissions caused by insufficient urea injection, but also prevents urea waste and crystallization blockage caused by excessive injection, and adapts to changes in working conditions of different loads and speeds.
3. Protect the post-processing system and extend the life of components
-Through precise volume control and efficient atomization, the crystallization deposition of urea in the nozzle holes, flow channels and exhaust pipes is reduced, and the crystals are prevented from adhering to the inner wall of the SCR catalytic converter, preventing the catalytic converter from being clogged and poisoned.It also reduces the wear and failure rate of related components of the after-treatment system, indirectly extending the service life of valuable components such as the SCR catalytic converter and urea pump, and reducing high maintenance costs caused by component damage.
4. Monitor operating status and assist in troubleshooting
-The built-in related monitoring module can provide real-time feedback on its own operating status (such as injection pressure, atomization effect, and whether it is clogged), and transmit the data to the ECU, which meets the core needs of the equipment status monitoring system.When problems such as abnormal injection and blockage occur, the OBD alarm is triggered to remind the operator to check and repair in time.It also provides accurate data support for troubleshooting, reducing troubleshooting time and maintenance costs, and ensuring the normal operation of the equipment.
