Univ logo 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

Univ logo UKACC PhD Presentation Showcase Slide 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.

Univ logo UKACC PhD Presentation Showcase Slide 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
