Oxygen Sensors, also referred to as Lambda Sensors, are mounted on the engine exhaust manifold, to measure the amount of unburned oxygen in the exhaust gases, sniff exhaust gases and produce a voltage that can be read by the ECU, indicating that the air-fuel mixture is very poor or rich. In this way, the air-fuel mixture is kept under constant control in every driving condition of the vehicle, thus ensuring optimum performance and fuel economy. Many vehicles have an oxygen sensor malfunction lamp. At the same time, the driver complains of excess fuel consumption. Faulty Oxygen Sensor causes fuel consumption to increase up to 30%. Reduced driving comfort and combustion losses are classic Oxygen Sensor fault symptoms, all of which can be rectified by installing an appropriate Oxygen Sensor. laws have made it compulsory to use catalytic converters in vehicles and to pass emission tests once a year. One of the primary causes of a failed engine and exhaust emission test is a malfunctioning Oxygen Sensor. For this reason, Oxygen Sensors every 30.000 km. should also be checked once. Never avoid replacing the Oxygen Sensor when you experience one of the aforementioned faults in your vehicle. Saving in Fuel Consumption with Oxygen Sensor Saving the amount of oxygen in the exhaust gas and generating 50-900 mV voltage at the operating temperature (above 300 ° C) depending on the amount of oxygen in the exhaust gas to the electronic brain. Transmitting information about the oxygen sensor, it ensures optimum levels of fuel consumption. The oxygen sensor, which was first used by Bosch in 1976, has been produced more than 350 million pieces to date. How Does the Oxygen Sensor Work? The control device, the ratio of the mixture from the voltage output of the oxygen (lambda) sensor. detecting (poor or rich). The amount of fuel injected is adjusted to ensure the ideal mixing ratio. If the mixture is very rich, the amount of fuel sprayed decreases. Similarly, if the mixture is very poor, the amount of fuel injected is increased by the command delivered to the injectors by the brain. The oxygen sensor transmits information about the amount of oxygen in the exhaust gas to the brain and ensures optimum levels of fuel consumption. Therefore, an oxygen sensor is needed to detect the amount of oxygen contained in the combustible gases leaving the engine to be released into the atmosphere. When the oxygen sensors produced to card this need are removed from the vehicle, the control unit detects the oxygen sensor signal as zero. Since this means a poor mixture, it tries to enrich the mixture by increasing the open time of the injections, thus increasing the fuel consumption of the engine. If more than one ... Some vehicles have more than one oxygen sensor. Because these vehicles have one lambda before and after catalyst. Before the catalyst, lambda detects the amount of oxygen contained in the exhaust gases resulting from combustion and warns the control unit to determine an optimum spray amount. After the catalyst, lambda transmits the catalyst's treatment performance information to the control unit by measuring the exhaust gases that the catalyst purifies from the bad effect. Advantages of the oxygen sensor The lambda sensor is a key part of a vehicle's gas injection system and is a major factor in fuel economy. If the sensor operates at the desired level, the engine can operate at full performance capacity and meet the required emission limits by law. Regularly checking and replacing Lambda sensors is an important and necessary process for your vehicle. Lambda sensor should work properly to ensure emission limits and to reduce fuel consumption.
