AN ENGINE TEST BED FOR THE INVESTIGATION OF DYNAMIC RUNNING CONDITIONS

In the development of internal combustion engines it is important that not only stationary but also dynamic running conditions be investigated. An engine test bed designed for this purpose should have the possibility of simulating as far as possible the dynamic conditions which exist in a running vehicle. This vehicle simulation should especially be designed as "On line simulation" and for the simulation of gear shift and clutch processes. In this paper the most important requirements and problems are discussed and a practical model for a dynamic test bed is proposed. In the second part the problems involved with "the control of an internal combustion engine and the loading equipment" is discussed in more detail. The optimization method Evolutionstrategy is especially described. This program adapts the control parameter PID to the test cycle of the internal combustion engine and to the loading equipment.
