Honeycomb ceramic is a new type of ceramic product with a honeycomb-like structure. It is widely used in chemical, electric power, metallurgy, petroleum, electronic appliances, machinery and other industries from the earliest use in small automobile exhaust purification, and it is becoming more and more extensive, and its development prospects are considerable. Honeycomb ceramics are composed of numerous and equal pores in various shapes.actual production. Because of this, honeycomb ceramic catalysts are constantly innovating, and the market demand is also increasing. These catalysts for catalytic cracking are replaced by honeycomb ceramic catalysts. Honeycomb ceramic catalysts with large size and number of pores have emerged and have a strong development momentum.

catalytic converter is part of a car's exhaust system. Catalytic conversion device is an exhaust purification device that converts CO, HC, and NOx in exhaust gas into gases that are harmless to human body by using the action of catalyst, also known as catalytic conversion device. The catalytic conversion device converts the three harmful gases CO, HC, and NOx in the exhaust gas into harmless gases carbon dioxide, nitrogen, Hydrogen and water. According to the purification form of catalytic converter, it can be divided into oxidation catalytic converter, reduction catalytic converter and three-way catalytic converter. The ceramic carrier is also a key component of the catalytic converter. The urea pump is an important part of the urea solution injection metering system. Its main function is to extract the urea solution in the urea tank, maintain a certain pressure, and then deliver it to the injection unit to meet the requirements of the injection metering system for flow and pressure.A nitrogen oxygen sensor or NOx sensor is typically a high-temperature device built to detect nitrogen oxides in combustion environments such as an automobile, truck tailpipe or smokestack. The drive to develop a NOx sensor arises from environmental factors. NOx gases can cause various problems such as smog and acid rain. Many governments around the world have passed laws to limit their emissions (along with other combustion gases such as SOx (oxides of sulfur), CO (carbon monoxide) and CO2 (carbon dioxide) and hydrocarbons). Companies have realized that one way of minimizing NOx emissions is to first detect them and then to employ some sort of feedback loop in the combustion process, thereby enabling the minimization of NOx production by, for example, combustion optimization or regeneration of NOx traps. Therefore, in many applications with exhaust-gas treatment systems, one NOx sensor is used upstream of the exhaust-gas treatment system (upstream) and a second sensor is used downstream of the exhaust-gas treatment system. The upstream sensor is used for the aforementioned feedback loop. Meanwhile, the downstream sensor is used mainly to confirm that the legislated emissions limits have not been exceeded.
