EACS Engine Altitude Conditions Simulator

The majority of equipment and protocols found in Engine Test Cell Facilities are heavily constrained by standards and regulations, so it is not often that something truly innovative comes along. However, the EACS is just that; an outstanding development that test facility managers have been waiting for.  Engine (and vehicle) testers have to carry out trials under a variety of environmental conditions, including at low pressure to simulate high altitude testing. Until now such testing has involved enclosing the engine(at the very least) within an environmental chamber that can withstand lowered pressures whilst managing air and emission gas flows in and out of the system to sampling arrays and the like. Highly complex engineering is always involved and the engine is effectively off limits whilst the testing is done. Not very convenient and very costly.

The EACS effectively fits across the engine / power unit instead of enclosing it and actively manages pressures to simulate constant altitudes from 800 meters below sea level as high as 5,500 meters above sea level. In order to obtain very stable pressure conditions during transient tests (fast variations of intake air, exhaust gas and fuel flow rates), the EACS produces the desired pressure levels within a single volume, from which the engine draws the required flow of intake air and into which it introduces the flow of exhaust gas. The engine is accessible all the time, the testing facility does not have to manage expensive low pressure containment rooms / systems and the energy demands are considerably less than traditional altitude simulators. 

The EACS system can be delivered in different sizes,  for different engine sizes from small gasoline car engines to large heavy duty diesel engines.
