Method for controlling an injector with verification of plunger movement |
摘要 |
<p>A method for controlling an injector (2) with verification that plunger movement has occurred; the method providing application of a time-variable voltage (Vinj) to the terminals (5, 6) of an injector (2) drive circuit (4) in order to cause a current wave (linj) to flow through said drive circuit (4); detection of a verification voltage (Vv) between the terminals (5, 6) of the drive circuit (4) once the current (linj) through the drive circuit (4) has died away at the end of the injection phase, measurement of a verification time (Tv) during which the verification voltage (Vv) is greater than a first predetermined threshold value (SVv) and diagnosis of the absence of plunger movement if the verification time (Tv) is less than a second predetermined threshold value (STv).</p> |
