ACCURATE – DYNAMIC – EFFICIENT Altitude simulation for R&D The topic of Real Driving Emissions (RDE) is becoming more and more ­mpor­ ant. Accurate testing is i t e ­ ssential to ensure internal combustion engines meet global emission and modern performance standards under various altitudes during real driving conditions. Until now, altitude chambers have been used for this testing, but cost, flexibility, accuracy, and energy consumption have always been a concern. A unique tool, the MEDAS altitude simulator, has been designed specifically to address these concerns. This mobile solution...

STAY UP-TO-DATE ON SIMULATION Get control of your parameters Stay up-to-date on RDE, Rig-to-Rig and Road-to-Rig correlation as well as validation / verification / fuel e ciency. MEDAS has been developed using effi ffi cient energy consumption technology, which is powered via electric motor driven chargers and compressors. They work with ultra-high-speed components to g enerate the required intake air and exhaust conditions to the engine in time with highest accuracy. This eliminates the need for huge media storage buffer as has been required in the past. ...

FLEXIBLE FOR STEADY STATE AND DYNAMIC APPLICATION If you are dealing with RDE development targets, MEDAS offers you simulation of altitude or ambient c onditions under desired temperature, humidity and pressure. Correlation of pressure and mass flow at engine intake and exhaust ensures exact conditions at your engine under test. 2,000 MEDAS-5012 VO in overpressure mode MEDAS-5012 VO in vacuum mode MEDAS-5009 V in vacuum mode MEDAS operation range as a function of altitude and mass flow. Functional extensions can compensate for non-covered area (see page 5 and 6). EASY TO OPERATE You...

New legislation requires automotive manufacturers to test their vehicles at defined and varying altitudes to reflect actual driving conditions. Two additional options are available to ensure compliance with the new standards: the MEDAS Temperature Module (MTM) and the MEDAS Humidity Module (MHM). These additional modules allow tests to be carried out in a temperature range of -15 to 40 °C at altitudes up to 5,000 meters above sea level and respective humidity from 10 to 80 % as a standard. The functional extensions enable simulations within a wider range of ambient pressure, temperature and...

MEDAS TEMPERATURE MODULE The MEDAS Temperature Module (MTM) is a complementary option for the MEDAS altitude simulator. The MTM xtends the temperature range available for altitude testing. This makes it possible to simulate e any temperature between -15 and 40 °C, at altitudes ranging from sea level to 5,000 m above sea level independently of the location and also under dynamic operation. MEDAS HUMIDITY MODULE THE MEDAS Humidity Module (MHM) is an extension module for humidity control that operates in ...
