OXYGEN SENSOR 专利名称：OXYGEN SENSOR 发明人：SUGIYAMA YUJI,SUGIMOTO KEISUKE 申请号：JP27312388 申请日：19881031 公开号：JPH02120653A 公开日：19900508 专利内容由知识产权出版社提供 摘要：PURPOSE:To enhance measuring accuracy by removing a measuring error by providing a control circuit for making heater ...
To shorten the time during which oxygen concentration cannot be detected, the temperature of an oxygen concentration sensor is detected by negatively biasing the sensor using a bias control circuit. A microcomputer estimates a saturated current thereof at one time before the current flowing through the...
AIR-FUEL RATIO CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE An air-fuel ratio control device is provided with a constant current circuit that changes the output characteristics of an upstream oxygen sensor (25) by supplying a constant current between sensor electrodes of the upstream oxygen senso.....
A heater is provided to control the temperature and, under open circuit conditions, an e.m.f. develops between the porous outer (measurement) and inner (reference) Pt electrodes. When the system is in thermodynamic equilibrium, the sensor senses only the oxygen partial pressure in the ...
I am getting DTCs as follows: P0171-System to lean, Bank 1, freeze frame; P0174-System to lean, Bank 2; P0141-02 Heater Circuit, Bank 1, Sensor 2; and P0161-02 Heater Circuit, Bank 2, Sensor 2. Could these 4 codes all be related to the same problem? If so, what could .....
The sensor has a standard air interface, which enables calibration check on the site and provides convenient maintenance. It adopts single-chip control and data processing with quick response, accurate measurement and stable performance. Technical indexes 1.Measuring range: 0~20.6%02...
PURPOSE: To surely judge the degradation of a main oxygen sensor by detecting the variation of the output signal of an auxiliary oxygen sensor, a feed-back control value and learning control value to judge the degradation of the main oxygen sensor when a time for continuing the condition of ...
PURPOSE:To obtain the sensor which is free from deterioration of the initial characteristics and durability and has stable characteristics by constituting the protective layer of an electrode of a multilayer structure which becomes a layer of small particle size as it is provided toward the inside. ...
