What Does the Engine Data Analyzer Do?
When a gasoline-powered engine burns gasoline there is oxygen present. Oxygen in an engine is the result of a number of factors including the air temperature, altitude, engine temperature, load on the engine, and barometric pressure. The ideal ratio for oxygen and gasoline is 14.7:1, which slightly varies depending on different types of gas. In the instance that there is less oxygen present fuel will remain after combustion, which is referred to as a rich mixture. On the other hand, if there is more oxygen present it is referred to as a lean mixture. Both the rich and lean mixtures are bad for your car, as well as for the environment. A rich mixture results in a fuel that is not burned which creates pollution. A lean mixture generates nitrogen-oxide pollutants, which can lead to decreased vehicle performance and engine damage. EDA sensors are positioned near points in the exhaust system so to determine if there are rich or lean mixtures in your engine. Typically, an EDA sensor creates a voltage due to a chemical reaction resulting from an off-balanced gasoline to oxygen ratio. Most engines can determine how much fuel to expend into the engine based on the voltage of the EDA sensor.
