Original urea sensor for high-quality spare parts

Product description

At present, the requirements for automobile emissions are increasingly high, especially the NOX(NO and NO2) emissions of diesel vehicles have certain toxicity, so the SCR system (selective catalytic reduction system) of diesel vehicles has increasingly high requirements for exhaust post-treatment. In the SCR system of diesel vehicles, under the action of catalyst, liquid urea is sprayed as a reducing agent to reduce NOX in the exhaust gas to N2 and H2O. The urea dose in the SCR system is ultimately controlled by the engine management system, and the amount of urea injected must match the concentration of NOx. While ensuring the reduction of nitrogen oxides, the amount of urea should not exceed the prescribed amount. Because the injection amount of urea is too little, can not reach the due level of treatment, the injection amount of urea is too much, will make the excess ammonia gas discharged into the atmosphere, causing new pollution. In addition, the injection amount of urea is closely related to the real-time pressure of liquid urea. Urea pressure sensor for vehicle is complex in structure. Specializing in the manufacture of common rail pressure transmitter, hydraulic pressure sensor, water pressure sensor, CNG/LPG high pressure sensor, water purifier pressure transmitter, urea pressure sensor, etc.
