Electromagnetic driving valve control apparatus for internal combustion engine, supplies desired current to electromagnet based on comparison between generated desired velocity and detected velocity of moving unit

摘要

The sensors (2,3) detect velocity and position of moving unit having a needle, respectively. A generator (5) generates desired value of velocity depending on the signal from sensor (3). A comparator (4) compares the desired value of velocity and signal from sensor (2) based on which desired value of current is supplied to an electromagnet from generator (6). An Independent claim is also included for electromagnetic driving valve.
