摘要
氧化钛式氧感器的功用是通过监测排气中氧离子的含量来获得混合气的空燃比信号,并将空燃比信号转变为电信号输入发动机ECU。ECU根据氧传感器信号对喷油时间进行修正,实现空燃比反馈控制(闭环控制),使发动机得到最佳浓度的混合气,从而达到降低有害气体的排放量和节约燃油之目的。
The titanium dioxide is the function of type oxygen sensor by monitoring the exhaust oxygen ion content in the gas mixture air-fuel ratio to get the signal,the signal into electrical signals and the input air-fuel ratio the engine ECU.ECU oxygen sensor signal based on corrected fuel injection time to realize air-fuel ratio feedback control（closed-loop control）,the concentration of the engine to get the best gas mixture,which can reduce harmful gas emissions and fuel economy purposes.
