Automotive Sensor past simply for the engine, has been extended to the chassis, body and electrical lighting the system. These systems use sensors have more than 100 kinds. In a wide variety of sensors in common: intake pressure sensor: to reflect changes in the size of the absolute pressure sensor type car intake manifold, is the ECU (engine control unit) to provide the fuel injection duration calculation of the reference signal; air flow meter: measuring the amount of engine intake air is provided to the ECU as the injection time of the reference signal; Throttle Position Sensor: throttle opening angle measurement sensors on the car, as off the oil supplied to the ECU to control the fuel / air ratio , the ignition advance angle correction of the reference signal; crank position sensor: detects the crankshaft and the engine speed, as provided to the ECU determines the ignition timing and sequence of operations of the reference signal; oxygen sensor: detecting the oxygen concentration in the exhaust gas supplied to the ECU as the control fuel / air ratio in the optimal value (theoretical value) of the reference signal near; automotive sensors - sensors are used to detect gas concentration in vivo gas and car exhaust emissions. Among them, the most important is the oxygen sensor, which detects the vehicle exhaust oxygen content, air-fuel ratio determined according to the oxygen concentration in the exhaust gas, to the computer control means issuing a feedback signal automotive sensors, to control the air-fuel ratio converges to the theoretical value. When the air-fuel ratio becomes high, increasing the oxygen concentration in the exhaust gas, the oxygen sensor output voltage decreases; when the air-fuel ratio becomes lower to reduce automotive sensor supplier, the oxygen concentration in the exhaust gas, the output voltage increases. The electronic control unit recognizes this mutation signal to the fuel injection quantity is corrected, thus adjusts air-fuel ratio to near stoichiometric change.
