Oxygen Sensors are used in modern automobiles to control the fuel and ignition systems to optimize a car’s performance in the areas of emissions and fuel economy. Sensors are located before and after the catalytic converter to check on the amount of oxygen in the exhaust. The sensor sends signals to the car’s on-board computer, which then can adjust several variables, including air/fuel ratio and timing, in order to bring the engine into the optimum operating range.

Each NTK Oxygen Sensor is:

  • Extensively Tested During Manufacture to Guarantee Quality and Reliability
  • Supplied With a Factory-Fitted OEM Connector for Easy Installation
  • Precision manufactured with a sensing element incorporating NTK’s premier technical ceramics


p14Oxygen Sensors for automobiles

In order to meet strict emissions regulations the catalytic converter(CAT) needs to clean the exhaust gas as effectively as possible. The CAT is most efficient at the stoichiometric air-fuel ratio(the point of complete combustion) as shown in the right figure, therefore controlling engine fueling in a narrow window around this point produces the cleanest exhaust gas.

As a central component of emissions treatment systems, oxygen sensors are the most commonly used method of air-fuel ratio control. They deliver high performance and reliability to meet strict emissions regulations.

NGK spark plugs and NTK oxygen sensors are available with DSL and their dealers islandwide.
