Control circuit for fuel injecting valve for fuel injection system of internal combustion engine, has two magnet coil for electromagnetic actuation of fuel injecting valve where both magnetic coil are separately controlled

摘要

The circuit has two magnet coils (7a,7b) for the electromagnetic actuation of the fuel injecting valve. Both the magnetic coils are separately controlled over a common control device (23) and a variable number of output stages (22). The magnetic coils are wounded on a spool carrier and are enclosed in spool housing.
