#Adaptronic piezo injector drivers#
Most automotive DI injector drivers share 2 up to 4 injector outputs per hi side driver meaning only one of these injector outputs can be active the time giving complications when pilot and post injections are needed. Also every DI injector driver output has his own hi side driver stage and this will make it possible to fire the injector independent without limitations to timing and duration. The INJ drivers are build to industrial standards and use power recovery from the injector coils in a way that not only we have extreme low power consumption but our drivers store the energy making it possible to run hi RPM on the engine and still have the ability to fire the injector in rapid succession without dropping power for the boost phase of the injector coils so peak current is consisted giving the guarantee that injector timing and metering remains within injector specification.
