The relation between temperature and pressure in fluids and gases offers a high potential for the development of different applications. Test consistency and reproducible conditions are in high demand particularly for exhaust emissions. Compared to the real application on the road, there are normally constant ambient conditions in the test cell. To prepare the engines for those real situations, it is necessary to simulate different conditions like altitude or climatic conditions in the test cell. High efficiency in testing requires high reliability and high reproducibility of the control and measurement result in a wide application range. APPROACH The performance of combustion engines strongly depends on the media conditions. For better reproducibility under almost real conditions there is a need for a high dynamic control of the media conditioning units. For 25 years AVL has intensively developed different compact conditioning systems and technologies which are used in high-end engine test cells. If standard systems are not enough, AVL designs customer-specific units. BENEFITS AT A GLANCE • A modular design makes it usable in a wide range of situations. For different applications, various modules are available • High control accuracy in steady state and dynamic mode ensures exact data from the test procedure and increases the testbed efficiency • Extreme temperature and pressure ranges for simulating conditions / 100 at the test bench which are hard to achieve on the road • Easy integration with the automation system enables a quick initialisation (plug & play) • Good repeatability allows a fast achievement of the development goal • Minimized downtime with robust and reliable design • Short commissioning time • Flexible use due to mobile design • Less maintenance work required
