Sensors
In automotive vehicles, sensors are used to measure the operating conditions and changes of the vehicles.
Mainly following types of sensors are used in vehicles
Oxygen sensor: Oxygen sensor is used to estimate the proportion of analyzed oxygen. The concentration of
gases emitted through it can also be measured.

Frank sensor: This electronic device is used to monitor internal combustion engines and their rotational speed.
Through this, the rotational speed of the piston and valve can also be monitored.
Cold temperature sensor: This type of sensor is used to measure the lubricant temperature present in the
vehicle engine.
Temperature sensor: This type of sensor can be used to detect different temperatures; Such as fuel temperature,
coolant temperature, intake temperature, used to measure air temperature etc.

Vehicle speed sensor: The speed of vehicles is monitored with this sensor.
Injection pump speed sensor: This type of sensor is used to monitor the rotation speed of the pump.
Fuel rack position sensor: This type of sensor is used to monitor the position of the fuel rack.
Air flow sensor: Air flow sensor is used to measure the rate of air flow coming into the fuel injection engine.

Apart from all the above sensors, some other sensors; Such as fuel pressure sensor, air cleaner vacuum pressure
sensor, brake pedal sensor, clutch pedal sensor, driver input switch sensor are also used in vehicles.
Actuators

Actuators are used to transfer electrical signals into mechanical action. Electromagnetic actuators are used
in electronic diesel control systems. These types of actuators are located on the fuel pump. To transfer the
electric signal into mechanical action, sensors like boost pressure actuators, throttle valve actuators, exhaust gas
recirculation actuators etc. are used.
