Unsteady Interaction Of Turbocharger Compressor With IC Engine

Growing global concern pertaining to climate change has meant
that engine development has become more focused on engine
emissions. A method of reducing the emissions of an internal
combustion (IC) engine is to use smaller engines but recover
power lost due to reduction in size by using a turbocharger or
supercharger.
To ensure that a turbocharger is appropriate for a given engine it
has to be matched correctly. This process is called turbocharger
matching. Turbocharger matching ensures that the compressor is
providing sufficient air to the engine over a wide range of operating
conditions.
Currently compressors are mapped by carrying out controlled
experiments which put limits on its applicability to real world
situations.
