METHOD FOR THE DIAGNOSIS OF A DROP IN LOAD

摘要

The invention relates to a method for diagnosing a drop in load on a piezo actuator in an injection arrangement. In said diagnostic method, a voltage is measured and is compared with a threshold voltage (24). There is a drop in load if the measured voltage is greater than the threshold voltage (24). The invention further relates to an arrangement for diagnosing a drop in load on a piezo actuator in an injection arrangement, a computer program, and a computer program product.
