METHOD AND DEVICE FOR OFFSETTING BOUNCE EFFECTS IN A PIEZO-ACTUATED INJECTION SYSTEM OF AN INTERNAL COMBUSTION ENGINE |
摘要 |
<p>The invention relates to a method and a device for offsetting bounce effects in a piezo-actuated injection system of an internal combustion engine using a control valve actuated by a piezoelectric actuator. The inventive method comprises the following steps: detecting an actual bounce behavior of the control valve, and determining and offsetting a deviation between the actual bounce behavior and a desired bounce behavior of the control valve, thereby generating an actuation information for the control valve which influences a speed characteristic of a needle of the control valve. The invention also relates to a device for carrying out the inventive method.</p> |
