The DMg06 driver owns 6 inductive injectors high tension command channels. It can only be used with Commander ECUs series (for other ECU types, do use DMS06 driver).

This driver is used in the gazoline direct injection, diesel common rail and diesel pump injectors kits.

GENERAL OPERATION
DMg06 is a driver specifically dedicated to the command of inductive injectors requiring a Peak and Hold command with a high tension and a strong current of Peak, and a regulated current of Hold.
It provides the high tension of the peak thanks to a switching mode power supply located in its housing.
Unlike most of its competitors, it is designed to allow injection covering of a channel on the other one (between cylinders), allowing (in diesel common rail):
• Very advanced Pilot injections even at high rpm, which reduce the cylinder pressure to obtain more power
• To perform pilot injections along with late post injections

CARE OF USE
A capacitor of strong capacity being integrated into the switching mode power supply, the high tension can remain much later the complete switch off of the driver:
• It is forbidden to open the housing.
• It is forbidden to manipulate the driver or the connections of its loom within the 3 minutes following its complete switch off.
The strong power delivered in case of extensive use (high engine rpm and important number of injections by engine cycle, high tension of injectors) provokes a strong rise of the internal temperature. The housing of the driver being used to dissipate this temperature, it can reach temperatures higher than 100 °C.

CHARACTERISTICS
• 6 channels of injectors commands
• Inputs commands by the ground, 1 KOhm pull-up resistor to +12V After Key integrated into the driver.
• Response time: 2 µs
• Injection covering of a channel on the other one (between cylinders) allowed
• Maximal power delivered to injectors for the peak current: 100 watts
• Programmable peak tension from 20 volts to 65 volts
• Duration of peak attack from 50 microseconds to 1000 microseconds
• Peak withstand current by adjustable switching
• Hold current adjustable from 1 to 16 amperes
• Average maximum number of injections for all channels cumulated: depends on the current and on the duration of the peak: for standard diesel inductive injectors: 42000 injections/mn (6900 t/mn - 6 cylinders - 2 injections per cylinder, 10350 rpm - 4 cylinders - 2 injections per cylinder)

INJECTORS MANAGEMENT
The injectors command is configurable to adapt to the needs of the injectors to drive.
This command is composed of two main parts:
The peak delivers a high voltage under a strong current for a few hundred microseconds. This peak is a necessary part for a very rapid opening of the injectors. It is itself composed of two phases:
• The attack during which a high voltage (adjustable up to 65 volts) is applied continuously until getting a large current (can exceed 20 amperes)
• The withstand for which a switching of the high voltage is made to keep on the current level (adjustable length and switching).
The Hold, during which the voltage is supplied by the engine 12 volts battery supply with current control by switching the battery power to maintain the opening of the injector without damaging it by an excessive rise of its coil temperature (level of hold current adjustable from 1 to 16A).
