The series of electronic control units Vento, by AEB, are designed for LPG or CNG applications on multipoint engines from 3 to 10 cylinders.
During gas operation, based on the petrol injection time, the gas pressure and temperature, the control unit calculates the amount of equivalent gas that must be injected in the gas phase into the intake duct to have the same engine performance as would have petrol.
The OBD versions, thanks to the communication with the OBD protocol from the original petrol control unit, adapt the system so as to compensate for drifts and aging of the gas components.
All units are equipped with a diagnostic system for all gas components, to avoid any malfunction problems and facilitate any technical interventions
