Injection valve i.e. high pressure injection valve, operating method, for internal combustion engine, involves opening injection valve, closing injection valve, supplying counter current and controlling intensity of counter current

摘要

The method involves opening an injection valve by supplying a current (74) and closing the injection valve by stopping the supply of current. Counter current (76) is supplied for accelerating the closing operation of the injection valve as soon as the current (74) is reduced to zero during the closing operation. The intensity of the counter current is controlled during operation. A closing voltage (66) is applied to a solenoid coil (48) of the injection valve. Independent claims are also included for the following: (1) an injection valve operating device comprising a solenoid coil (2) a computer program for performing a method for operating an injection valve (3) a computer program product for performing a method for operating an injection valve.
