Webb10 juni 2024 · There are two primary types of O2 sensors in use today: conventional zirconia and wide-band. A conventional O2 sensor can only react as a rich-lean indicator to an air-fuel mixture within a certain range. On the other hand, a wide-band O2 sensor can detect the exact mixture over a much wider range for more precise system monitoring. WebbAutomotive engines have three primary areas of operation, which include idle/cruise, wide-open throttle, and fuel cut-off. On gasoline engines, the ideal wide-open throttle is typically around a ratio of 10.5:1; with idle/cruise at 14.7, and fuel cut-off at 20:1. Tuning an engine to improve the air/fuel ratio to improve horsepower or fuel ...

When the fuel mixture is lean (more air, less fuel), an O2 sensor typically produces a low voltage signal (less than 0.2 volts).
