DESCRIPTION
Ref.: 9EQ304AA6C – 230 V
Ref.: 9EQ304AA3C – 115 V
Equipment to study how the electronic control unit (ECU) of a petrol engine works with a multipoint sequential injection system and static ignition. The equipment enables, by means of a series of potentiometers, different operation conditions to be simulated (amount and air mass, temperature, rpm, cooling temperature etc.) which the ECU, depending on the programming, uses to carry out the necessary calculations and make the different system actuators work (injectors, coils, air flow valve, electrofan, etc). Input and output signals can be adjusted independently. Nevertheless, to avoid malfunctions (unlikely) on the injected system, an AUT mode has been implemented where the sensor signals evolves depending on the programmed algorithm thus allowing the student to quickly begin to understand how the injection system works. Similarly, it incorporates the auto-diagnosis system which alongside the DD-Car software allows the student to become familiar with auto-diagnosis techniques.
