AEB, the Italian autogas system electronics provider, has launched a new ECU for engines with direct petrol injection. The device constantly monitors petrol injection time and pressure in the fuel rail to adjust the autogas dose in such a way that engine performance remains unchanged.

The DI60 works efficiently in a broad range of ambient temperatures (from -40 up to 125° C) and its aluminium housing is characterised by top International Protection Rating grade, determining an electrical device's protection against penetration by outside agents. Thus the ECU is considered fully waterproof.

It features a 60-pin connector with a lock and a lever for easy unlocking. The connector has an IPX9K protection rating, which means its resistant to water under high pressure, e. g. during carwash visits.

Furthermore, the DI60 supports numerous sensors. The conversion kit includes the new, easy to mount PT sensor (MAP sensor), whose role it is to measure LPG pressure and temperature in the intake manifold. The DI60's new functions enhance the entire system's control and diagnostics, all the while warranting, according to AEB, oustanding engine performance under all loads and conditions and making the calibration process easier. The ECU offers the option of measuring voltage on the petrol injectors without connecting an oscilloscope or other peripheral devices.

The DI60 is dedicated to 3- and 4-cylinder engines. It features 2 sockets for powering LPG electrovalves. Each supports 2 A current (25 W power), but using one instead of both means the parameters can be boosted to 4 A/50 W. The ECU communicates with the petrol system through OBD and supports the following protocols: ISO15765 (CAN bus), KWP2000 and ISO9141 (K-Line).

The controller can be used for both LPG and CNG systems as it is certified to comply with both the 67R-01 and the 110R-00 regulations, as well as the 10R-03, which determines an electrical device's electromagnetic compatibility, i. e. its resistance to electromagnetic interference and the level of emission of such interference.
