As one of the important members of the SCR system, the Nox sensor consists of a sensor probe and an electronic control unit. They are connected by wire harnesses and are used to measure the concentration of nitrogen oxides and oxygen in the exhaust gas. In practical applications, the probe is installed in the automobile exhaust pipe, and the exhaust gas concentration is fed back to the electronic control unit in the form of voltage through the ceramic chip. The heating temperature of the sensor probe is controlled by electronic control and through a series of signal conditioning, the concentration of Nox and oxygen in the pump is finally determined. The electronic control unit communicates with the vehicle control center (ECU) through CAN, and transmits the measured gas value to the vehicle control center (EUC) in real time, providing a basis for the SCR injection amount, thereby reducing NOx emissions.

Excavators can also pick up beer products, excavators can waltz, excavators can also play drift, these powerful performances, I believe you have seen from television, the Internet, right? Amazed at such a big head but there is such a sensitive performance, Xiao Bian is very interested in its unique skills, and now it is along with Xiao Bian to understand the excavator.
There are many kinds of excavators. There are two types of excavators: Internal-combustion engine driven excavator and electric-driven excavator. Excavators can be classified into track-type excavators and wheel excavators according to different types of driving methods; Can be divided into hydraulic excavators and mechanical excavators; according to the use of points, excavators can be divided into general excavators, mining excavators, marine excavators, special excavators and other different categories; according to the bucket points, mining Machines can be divided into front shovel shovels, backhoe excavator shovel shovels and grab shovels.
Today's excavators account for the vast majority of all-hydraulic full-slewing excavators. The hydraulic excavator is mainly composed of an engine, a hydraulic system, a working device, a traveling device, and an electrical control. Hydraulic system consists of hydraulic pump, control valve, hydraulic cylinder, hydraulic motor, pipeline, fuel tank and other components. The electrical control system includes a monitoring panel, an engine control system, a pump control system, various types of sensors, solenoid valves, and the like. This series of devices combined with the superb technology of the driver has made us see the exquisite one after another excavator.
