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 air pressure sensor: reflect the intake manifold absolute pressure sensor the size of the change car which is provided to calculate the duration of the injection ECU (engine control unit) of the reference signal ; air flow meter: automotive sensors measure the amount of air inhaled recognition engine, fuel injection time to the ECU as a reference signal; a throttle position sensor: measuring the angle of the throttle open, as provided to the ECU off oil, 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: detects an exhaust oxygen concentration sensor wholesale car, provided to ECU as the control of fuel / air ratio in the optimal value (theoretical value) in the vicinity of the reference signal; here we come to know about the main sensor on the car. Air flow sensor is the sucked air into electrical signals supplied to the electronic control unit (ECU), as one of the signals determines the basic fuel injection. Depending on the measuring principle, can be divided into the rotor blades air flow sensor, Karman vortex air flow sensor tours, hot air flow sensor and the hot film air flow sensor four types. The first two for both volume flow type, after the mass flow type. The main use of hot air flow sensor and two kinds of hot-film air flow sensor.
