Method for controlling an injector with verification that plunger movement has occurred |
摘要 |
A method for controlling an injector with verification that plunger movement has occurred; the method providing application of a time-variable voltage to the terminals of an injector drive circuit in order to cause a current wave to flow through said drive circuit; detection of a verification voltage between the terminals of the drive circuit once the current through the drive circuit has died away at the end of the injection phase, measurement of a verification time during which the verification voltage is greater than a first predetermined threshold value and diagnosis of the absence of plunger movement if the verification time is less than a second predetermined threshold value.
