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.
While driving, do not press the accelerator pedals to the end, most often we drive at medium speed, The computer driver settings are optimally prepared for just such a driving style. The oxygen sensor in the exhaust gas, the lambda sensor, measures the amount of oxygen remaining after combustion.
This gives information on whether there is excess air in the mixture and whether excessive or insufficient fuel is being injected. The engine controller will read this measurement and will continually adjust the amount of fuel injected so that the mixture is optimal. Due to the current strict emission regulations, the engine has many other systems that help reduce fuel consumption. It is therefore possible to supervise very accurately such processes as, for example, exhaust gas recirculation to drive the turbine, the amount of air and fuel injected, and the injection of additives such as AdBlue. Each of the above systems in some way affects the operation of the engine, and therefore must be under full computer control. Certainly, the engine controller by collecting a lot of data can find a fault at an early stage. For example, this may apply to pressure drop in the chamber, which may be a sign of seal failure. Of course, the computer will be able to determine exactly what type of our item is damaged, which can be seen on our dashboard or after connecting the laptop to the control unit. When our engine computer goes down, of course, you need to purchase the original engine driver, which will be fully compatible with our car.
