Urea injectors, as the core actuating components in the selective catalytic reduction systems of modern diesel engines, are widely used in commercial vehicles and heavy machinery that meet the National V and VI emission standards.Their performance is directly related to the conversion efficiency of nitrogen oxides in exhaust gases.Now let's analyze the features of this model for you.
1. High-precision injection control to improve reduction efficiency
The 2001791 urea injector uses electromagnetic drive or piezoelectric actuator, with microsecond response speed, and can achieve precise metering and atomized injection of urea solution.
2. High-temperature corrosion-resistant materials to extend service life
The key components of the injector are made of high-temperature and corrosion-resistant stainless steel and special alloy materials, which can operate stably for a long time in exhaust environments up to 700°C and effectively resist the chemical erosion of ammonia, moisture and sulfides produced by urea pyrolysis.
3. Integrated heating system, adaptable to low temperature environment
The built-in electric heating element can automatically start when the ambient temperature is lower than -5°C, preventing the urea solution from crystallizing or freezing the pipeline, ensuring normal injection during the cold start phase, and improving the system's adaptability and reliability in cold areas.
4. Wide operating voltage range and strong adaptability
Supports 12V/24V dual voltage platform, has a wide operating voltage range, adapts to the electrical systems of different models, and has multiple protection mechanisms such as overvoltage, reverse connection, and short circuit to improve system robustness.
