Current Research Work

  • The development of sustainable energy supplies is of fundamental importance to the modern world. As Director of the new Clean Energy Research Centre, I am interested in all aspects of energy conversion systems, particularly those that will be used to reduce our overwhelming reliance on fossil fuels.
  • Mixture motion in the combustion chamber of an internal combustion engine has an important impact on engine performance and exhaust emissions. Research work in this area is aimed at obtaining a better understanding of the relationships between combustion chamber design, turbulence generation, and engine performance. A new form of combustion chamber for spark-ignited engines in which it is possible to tailor the scale and intensity of turbulence prior to ignition has been developed. A partially stratified-charge engine combustion concept has also been patented, and is the focus of much of the engine research currently underway. A Ricardo Hydra single-cylinder research engine and AVL exhaust emissions analyzers, as well as a unique rapid-intake and compression machine, are used for research work directed at reducing exhaust emissions and increasing engine efficiency.
