Good condition of the oxygen sensor ensures engine efficiency

To meet pollutant emission standards and, at the same time, Ensure better engine performance, The automotive industry has begun to monitor the quality of exhaust gases more accurately. Keeping up with the trend, and NGK, leading candle maker, ignition cables and oxygen sensors of the world, made available to the market, sob a marca NTK, Oxygen Sensor, also known as lambda probe. Part of the electronic injection system, The component is responsible for identifying the condition of the air-fuel mixture, sending the information to the vehicle's control unit (ECU), which results in adequate fuel consumption, generating savings for the car owner.

With the data received, ECU verifies the need to correct the mixture, promoting the best performance ratio, consumption and emissions. In vehicles with flex system, The sensor also performs the function of assisting in the identification of the fuel used. To function properly, Oxygen Sensor, as well as other components, needs to be checked periodically. In poor condition, does not identify the mixture of air and fuel, which can cause the spark plugs to char and excess fuel in the catalytic converter, Impairing the performance of both parts. "With spark plugs and catalytic converter impacted by the non-functioning of the lambda probe, the vehicle will consume more fuel and increase pollutant emissions", warns Hiromori Mori, NGK Technical Assistance Consultant. According to the expert, Oxygen sensor wear is strongly associated with the use of poor quality fuels. "We observed a higher incidence of premature wear of this component in Brazil, where fuel adulteration is still common. That is why, The driver must refuel at trusted stations, and ask your mechanic to check the operation of the sensor." NTK supplies oxygen sensors to the world's largest automakers, Putting the same parts in the aftermarket, which are produced with high technology and quality, Avoiding incompatibility issues. Deadlines for review

Constantly subjected to vibrations, High temperatures and contact with exhaust gases, NGK/NTK expert recommends annual evaluation on oxygen sensor, or every 30.000 kilometers, by a qualified professional.

Second oxygen sensor

The second probe, mandatory since 2011 in gasoline-powered light vehicles, ethanol or CNG (Vehicular natural gas), is part of the OBD-BR2 system, On-Board Diagnostics (from English, on-board diagnosis system). Its function is to verify that the first sensor and the catalytic converter are achieving the expected results in the vehicle's emission control.

When the first one works irregularly, due to contamination, The vehicle's instrument cluster lights up with a warning light, indicating problems in the emission control system. Each vehicle has a specific oxygen sensor design, according to the NGK/NTK Application Table.
