The zirconium dioxide oxygen sensor with heater is equipped on shanghai BUICK to check the air-fuelratio of the mixture.
上海别克轿车装配了带加热器的二氧化锆氧传感器，用以检测混合气空燃比。

Through close loop control by an oxygen sensor, the actual air-fuelratio is controlled to the ideal air-fuel ratio and the exhaust emission is reduced by a three unique catalytic converter.
利用氧传感器实现闭环控制，将实际空燃比控制在理论空燃比附近，从而通过三元催化剂控制排放。

For airfuelratio signal of a gasoline engine, there exist transmission delay, which affects the control accuracy of airfuelratio using directive airfuelratiosensor signals.
