I didn`t have a clue. My experience is out of date. Injectors were timed
by a camshaft which generated little electrical noise.

Methods used to control radiation from Kettering ignition systems and
their solid-state derivatives should work on fuel injection timing
systems too.

The plan is to keep the electrical noise within a screened enclosure and
not let it out. It is hard to believe there is no DIN specification for
radiation from electrically timed fuel injectors. In the old days ther
was a specification for about everything.
