Flexible Air Pressurisation Systems
Engine downsizing coupled with a form of air pressure charging is considered a major potential route towards CO2 reduction. Birmingham City University’s Centre for Low Carbon Research is currently involved in a number of projects in which these challenges are explored.
One such project is exploring the use of electrically assisted decoupled turbocharger systems that work by implementing a fully electric (instead of mechanical) connection between the turbine and compressor and including an intermediate energy storage buffer. The use of high-efficiency electrical machines plus the energy storage buffer within a fully flexible control environment means that such a system can potentially offer:
- Transient performance improvements
- Turbocompounding opportunities
- Low speed boost enhancement (particulate burn off and torque gains)
- Aerodynamic blade re-optimisation
Birmingham City University are proud to work in partnership with Aeristech, one of the UK’s leading hybrid turbo charging organisations.
