  1. Control algorithms for optimisation of engine combustion process with continuously changing fuel composition By KinYip Chan Supervised by Prof. Andrzej Ordys, Dr. Olga Duran, Dr. Konstantin Volkov Kingston University UKACC PhD Presentation Showcase

  2. Introduction • Optimize four stroke engine combustion using electronic control • Current engines run limited profile (camshaft) • control valve timing and ignition timing according to piston position • Electronic control gives flexibility of controlling engine parameters which needed to run an engine • Project Aims: Fuel economy, less emissions, more choice on fuel composition. UKACC PhD Presentation Showcase

  3. Suggestion for content • Motivation for research • Fuel price increase – Give more choice for fuelling using different fuel composition (Petrol, Diesel, Biofuel, or mixed etc.) • Pollution issue – Less emission to provide better environment • Electronic control - is enabling feature to achieve more flexibility • Background • Pressure and temperature control inside cylinder • Takes data from sensors and control loop to update parameters for new cycles • Current status • Finishing a simulation platform using simulink • Finding control algorithm UKACC PhD Presentation Showcase

  4. Engine models Lotus Engine Simulation Ricardo Wave UKACC PhD Presentation Showcase

  5. Simulink model Simulink model (four stroke) UKACC PhD Presentation Showcase

  6. Results • Two zones temperature (Burned and unburned zone) • Ricardo Wave in blue, Matlab/Simulink in red and Ferguson in cross UKACC PhD Presentation Showcase

  7. Summary or future work • Engine simulation using computer programs • Using this as platform to build control algorithm • Future Works • Build a four cylinder engine • Compare simulation results with real engine test bed • Control strategies to optimise engine combustion performance UKACC PhD Presentation Showcase
