What Sensors Are Used in Cars?
1 Answers
Automobiles primarily utilize the following sensors: 1. Crankshaft position sensor and camshaft position sensor, which control the opening and closing sequence of engine intake and exhaust valves. 2. Front oxygen sensor and rear oxygen sensor, which monitor exhaust emissions and provide the central computer with data for optimal air intake and fuel injection, thereby optimizing fuel efficiency and meeting emission standards. 3. Oil pressure sensor, which triggers an alarm when oil pressure falls below a threshold. 4. Air flow sensor and throttle position sensor, which regulate throttle opening and air intake under different temperature conditions, especially during cold starts in winter by enriching the air-fuel mixture to increase idle speed. 5. Tire pressure monitoring system, which alerts when tire pressure is below (or above) the rated pressure.
