INTRODUCTION OF THE LABORATORY

turbofeltolto_laboratorium_8.jpg

The Turbocharging Laboratory makes it possible to map the real conditions and loads of turbochargers of different sizes and types. Its main aim is to offer - specifically turbocharger-optimized measurements
and tests in a time- and cost-effective way. Using extremely precise control technology, the test bench provides the ability to create compressor / turbine maps as well as a wide range of temperature, pressure and other parameter settings. An outstanding potential is the
feasibility of dynamic, long-lasting heat loading processes, in which the maximum temperature value can reach 1200° C. All this can be done by installing two turbochargers of the same type at the same time. During this type of test, the material ageing process of turbine housing due to thermal fatigue can be observed. In order to examine the conditions and different loads of the multistage charging, the test bench has a specially developed unit with which a pressure and temperature control can be established in a wide range of volume flows. The test bench also allows controlling the lubrication and cooling system of the turbocharger. The backpressure of the exhaust systems of internal combustion engines can be simulated by integrating them directly into the so-called "backpressure unit" system after the turbine.
