The engine controller is a unit that supervises and controls various elements of engine operation in our car. Basically it is a computer, switching system and energy management system.
Usually, it supports temperature and pressure sensors, and various types of data from other modules in the car, thanks to which the system will see how to control throttles. Examples include the coolant temperature sensor or the gas pedal position sensor. In addition, it supervises the anti-lock braking system ABS or traction control systems. In addition, the fuel injector will be checked, the ignition timing set accurately, the electronic throttle body opened or the radiator fan started. After collecting the data, the controller must make decisions about all settings on an ongoing basis. The control unit also collects all information, which it can then display on our vehicle’s dashboard. The engine controller also supervises electrical systems, where it must accurately determine the power supply voltage of individual devices in our car. Currently, in our cars computers control virtually every aspect, once we could see the amount of fuel or oil temperature.
Currently, in the engine compartment we find a lot of sensors that care about our safety, but also for comfort. For example, the engine computer controls the air-fuel mixture as it goes into the combustion chamber.
