The dynamic air conditioning unit (ACU) simulates charging systems for mono-cylinder or multi-cylinder engines on the test bench. The ACU enables two main fields of applications:
Based on the characteristic maps of compressor and turbine the built-in turbocharger modeling system allows real-time simulation of the compressor boost pressure in all map operating points. The optional back pressure control unit can be used on the engine exhaust line to dynamically emulate the turbine load.
