Description

Technical Field

[0001] The utility model relates to the technical field of oxygen sensor installation, and more specifically, to an oxygen sensor installation structure. Background Art

[0002] The oxygen sensor is a key feedback sensor in the electronic fuel injection engine control system. It is used to monitor and adjust the air-fuel ratio during the engine combustion process, thereby controlling exhaust emissions, reducing environmental pollution, and improving the quality of fuel combustion.

[0003] The oxygen sensor usually needs to be installed on the engine exhaust pipe through a mounting structure, and mainly measures the oxygen concentration in the exhaust through a ceramic sensitive element. Based on the principle of chemical equilibrium, it can convert the measured oxygen concentration into a voltage signal, which is then fed back to the electronic control unit (ECU). The ECU adjusts the injector based on these signals to maintain the air-fuel ratio of the mixture close to the theoretical air-fuel ratio (14.7:1), thereby optimizing the combustion process and reducing pollutant emissions.

[0004] Among them, it was found through searching that the patent application number CN202122242000.0 discloses an oxygen sensor installation structure, including a shell, a tightenable clamping mechanism is fixedly installed on the outer wall of the shell, a fixing bolt is welded at one end of the shell, a gasket is sleeved at one end of the fixing bolt, a first thread groove is opened on one side of the surface of the fixing bolt, a protective mechanism is threadedly connected at one end of the first thread groove, fixing mechanisms are welded on both sides of the outer wall of the fixing bolt, an outer protective sleeve is sleeved on the outer wall of the shell, heat dissipation holes are opened on both sides of the surface of the outer protective sleeve, and a heat conductive sheet is welded on the inner wall of the heat dissipation hole;

[0005] When this structure is in use, through the arrangement of the fixing block, the connecting plate, the iron sheet strip and the second threaded groove, after the fixing bolts and the exhaust pipe are fixed, the iron sheet strip can be wrapped around the outer wall of the exhaust pipe, and then the iron sheet strip can be fixed with bolts and nuts through the second threaded groove on the iron sheet strip, which can effectively maintain the stability of the oxygen sensor and make the connection less likely to shake. However, this structure is not easy to perform combing detection on the smoke after it is gathered when in use, resulting in poor detection effect of the device. Utility Model Content
