4. Detailed Component Information
4.1 NTC (Negative Temperature Coefficient)
The NTC is a protection device, typically connected between the positive and negative power inputs. In case of overload due to a short circuit or reversed battery polarity, the NTC heats up, creating a short circuit between the inputs. This action protects sensitive components by breaking the board's traces at the module entrance.
4.2 Diode
Rectifier diodes block current flow when voltage is exceeded. They prevent short circuits by allowing electrical current in one direction only. For injection plants, the rupture voltage of the Zener diode is typically 18.54 volts.
4.3 Voltage Regulator
The voltage regulator ensures the electronic circuit operates normally with 5 volts. It is crucial for the proper functioning of the ECU modules and the entire injection system.
4.4 Driver (Transistor)
Drivers are components responsible for triggering injector nozzles, ignition coils, and solenoids using a low-power electrical signal. A defective coil drive can lead to short circuits. Drivers can be individual power transistors or integrated circuits.
