| 发明名称 | Method and device for diagnosing an actuator for an exhaust-gas-driven supercharger | ||
| 摘要 | A method for testing a supercharger actuator for a supercharger of a supercharged internal combustion engine, including adjusting the supercharger actuator from a first position to a second position, determining a rotational speed change information, which is a function of the change of the rotational speed of the supercharger resulting from the adjustment, and establishing a malfunction of the supercharger actuator as a function of the rotational speed change information. | ||

| 主权项 | 1. A method for testing a supercharger actuator for a supercharger of a supercharged internal combustion engine, comprising: adjusting the supercharger actuator from a first position to a second position; determining rotational speed change information, the rotational speed information being a function of a change of a rotational speed of the supercharger resulting from the adjustment; and establishing a malfunction of the supercharger actuator as a function of the rotational speed change information, wherein the rotational speed change information is a difference between a first rotational speed in the first position and a second rotational speed in the second position. | ||
