Armature bouncing recognizing method for e.g. fuel valve, involves verifying whether actual flow characteristics correspond to reference-flow characteristics, and exposing anchor bouncing, when both characteristics do not correspond

摘要

The method involves assigning reference-flow characteristics to a solenoid valve (1). An actual flow characteristic is recorded and verified, whether the actual flow characteristics correspond to the reference-flow characteristics. An anchor bouncing is exposed, when the actual flow characteristics do not correspond to reference-flow characteristics. The characteristics of the anchor bouncing are recognized independent of the initial-flow characteristics, where the bouncing characteristics comprise of stroke level of the bounced anchor, and duration and frequency of the anchor bouncing. Independent claims are also included for the following: (1) a control device for controlling a solenoid valve (2) a computer program which runs in a control device for controlling a solenoid valve.
