The exhaust temperature sensor is used to measure the exhaust temperature of the engine, and its main function is to control the regeneration of DPF and participate in the calculation and control of urea injection quantity. In addition, the exhaust temperature sensor will also participate in the diagnostic calculation of the post-processing OBD system.

The ambient temperature sensor is used to measure the ambient temperature and input the temperature signal to the engine ECU and the post-processing DCU, so as to participate in the system operation and functional control of the engine and post-processing.

1. OBD diagnosis for DPF removal and DPF blocking faults;

2. Can trigger differential pressure protection when the DPF regeneration function is abnormal, such as a large deviation in the DPF carbon load model.

NOx sensors are installed in SCR (Selective Catalytic Conversion) systems to accurately and quickly measure nitrogen oxide (NOx) concentrations in gases. The NOx sensor communicates with the ECU through the CAN line, and a self-diagnosis system is integrated within the assembly. The sensor monitors its own working condition and reports to the ECU whether there is a fault through the CAN bus of the body.

TWC: Honeycomb ceramic as the carrier, on the surface coated with platinum, rhodium, palladium and other precious metals and rare earth coating, used in automotive exhaust system to CO, THC, NOx harmful gases harmless components.

GPF: Made of synthetic ceramic material, with honeycomb filter structure inside, using Eco Blue technology coated with noble metal slurry coating, used to solve the problem of PN emissions, and used with TWC, also has a certain effect on the conversion of harmful gases.

DOC: Treat the CO and HC in the exhaust gas and convert it into CO2 and H2O, so that HC and CO can reach the legal limit; NO is converted into NO2, which can be used for passive regeneration of DPF and rapid denitrification of SCR to improve passive regeneration efficiency. The SOF in PM is mainly composed of SOF and dry soot. The SOF in particles is processed and the dry soot is left to accumulate in the DPF. The model without DPF reduces the particles.

DPF: called wall flow particle catcher, that is, after the engine exhaust passes through the DPF, gaseous pollutants can flow out through the hole wall, and the particles are trapped inside the DPF by the hole wall. Then, under specific conditions, the C particles are converted into gaseous pollutants and discharged.

SCR: A treatment process for NOx in exhaust emissions of diesel vehicles. After adding ammonia to the exhaust gas, ammonia mainly reacts with nitrogen and oxygen compounds in the exhaust gas to generate harmless nitrogen instead of reacting with oxygen, so the reaction is called selective REDOX reaction.

ASC: To deal with the problem of ammonia leakage in the SCR catalyst in a dynamic environment, the ammonia leakage catalyst is specially added. The purpose of using the ammonia leakage catalyst is to oxidize the ammonia leaking from the SCR catalyst and convert it into a less harmful product, and the best case is to convert ammonia into nitrogen.

Urea pipe is used to transport urea hose, the tube body itself has a heating system to ensure that urea liquid can flow normally in winter.

After the vehicle is turned off, the compressed air generated by the DCU air pump reaches the urea pump through this pipeline, and is used to purge the urea in the flow channel, jet pipe and nozzle of the pump, avoiding the risk of blockage caused by urea crystallization.
