- Dynamic combustion engine test stand allows a very accurate analysis of the engine work. The prototype of such a system was developed and built in a cooperation of Poznan University of Technology with the ODIUT Automex company. The system consists of an asynchronous motor controlled by a regenerative variable-frequency drive with an ability to return braking energy back to the power system. Together they permit to set very precise work points of the combustion engine in every time moment, unlike test stands with eddy current dynamometer, which are only able to brake the engine. Measuring system is used to gather data from all sensors, especially torque sensor, which records the torque on a drive shaft. Sensors are connected to electronic boards, which provide signal processing, and data acquisition. Fuel mass flow meter with temperature and pressure control allows regulating the parameters of fuel supplied to the engine. A set of applications is used for test stand management and data presentation and visualization. Real conditions and vehicle dynamics are emulated using advanced models to allow a comprehensive research of the combustion engine on the test stand. The paper covers the description of developed system, its components, software and models adapted in emulation. Moreover, it provides schematics of the system as well as a block diagram of the vehicle dynamic model.
