1. 1. Compressor Modeling for Control of Automotive Two Stage Turbochargers

   Författare :Oskar Leufvén; Lars Eriksson; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : There is a demand for increasing efficiency of automotive engines, and one way to achieve this is through downsizing and turbocharging. In the design compromises are made, for example the maximum power of the engine determines the size of the compressor, but since the compressor mass flow range is limited, this affects the torque for low engine speeds.

3. 2. Modeling for control of centrifugal compressors

   Författare :Oskar Leufvén; Lars Eriksson; Lars Nielsen; José Galindo; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Downsizing and turbocharging of engines provide a way to meet increasing demands for efficiency and performance in the automotive industry. An engine design is a result of compromises, e.g. the selection of charging system, and the trend is to reduce these compromises by increasing system complexity. LÄS MER
