A new measuring device for measuring valve lift

The injection system is the main unit of diesel engines, having a major impact on proper operation of the engines. The delivery valve as an important element of the injection system assures its smooth functioning. In order to learn as much as possible about the movement of the delivery valve during the operation of the injection system, an inductive displacement transducer has been designed. The results of the measurements clearly indicate that the movements of the delivery valve are in agreement with the other measured parameters of the injection and that the proposed method for measuring the delivery valve lift can be successfully used with certain types of delivery valves.
