Problems solved by technology
[0003] The traditional nitrogen oxygen sensor still has some disadvantages. The nitrogen oxygen sensor on the market is susceptible to carbon deposits formed by particles in the exhaust gas, which will enter the interior of the nitrogen oxygen sensor and cause it to block. The accumulation of carbon deposits will reduce the power of the car and increase fuel consumption.

The invention discloses a nitrogen-oxygen sensor capable of preventing carbon deposition blockage. The nitrogen-oxygen sensor comprises a sensor main body, the two ends of the sensor main body are respectively and fixedly connected with mounting plates, the upper end of each mounting plate is fixedly provided with a monitoring joint, and the position, close to one side of the monitoring joint, of the upper end of the sensor main body is fixedly provided with a control unit. One end of the control unit is fixedly connected with a linear speed, one end of the linear speed is fixedly connected with a nitrogen-oxygen probe, one side of the nitrogen-oxygen probe is provided with a resonance mechanism, the resonance mechanism comprises a metal cover movably connected in one side of a nitrogen-oxygen probe, and four groups of vent holes are formed in the outer side of the metal cover. According to the nitrogen-oxygen sensor capable of preventing carbon deposition blockage, accumulation of carbon deposition is effectively prevented, vehicle power weakening is avoided, and meanwhile oil consumption is reduced.
Description
technical field [0001] The invention relates to the technical field of nitrogen and oxygen sensors, in particular to a nitrogen and oxygen sensor capable of preventing carbon deposition and clogging. Background technique [0002] With the improvement of people's awareness of environmental protection, there are stricter regulations on the exhaust gas emitted by automobiles, diesel engines and other motor vehicles, especially the content of nitrogen oxides in the exhaust gas. At present, the nitrogen oxide sensor is usually used in the after-treatment system of the automobile engine to measure the concentration of nitrogen oxides in the exhaust gas. According to the concentration value, corresponding measures are taken to reduce the emission of nitrogen oxides to meet the national standard. In order to improve the combustion efficiency of automobile fuel and reduce exhaust pollution, it has become the only way to develop and produce exhaust selective catalytic reduction system...
