the single particle ignition technique. The ignition temperature will be determined by using the direct thermocouple measurement technique. The ignition and combustion process will be recorded using the high speed CCD camera. By analysing the recorded images, other important parameters such as ignition delay time, volatile flame duration, burnout time, burning rate, can also be determined. Sub-project 4: Effect of NaCl addition to the acid-washed Zhundong lignite on its ignition and combustion characteristics in a single particle ignition apparatus The objective of this sub-project is to experimentally study the effect of NaCl (the major sodium contributor in Zhundong lignite) addition to the acid-washed Zhundong lignite on its basic ignition and combustion characteristics using the single particle ignition technique. Different NaCl loading will be applied to the acid-washed lignite using the impregnation technique. The ignition temperature will be determined by using the direct thermocouple measurement technique. The ignition and combustion process will be recorded using the high speed CCD camera. By analysing the recorded images, other important parameters such as ignition delay time, volatile flame duration, burnout time, burning rate, can also be determined. Zhang, Dongke, Professor Co-supervisor: Dr Mingming Zhu and Dr Yu Ma Fuel Efficiency and Emissions in Compression Ignition Engines Disciplines: Mechanical and Chemical Engineering This project aims to evaluate and compare the fuel efficiency and exhaust emissions from the combustion of diesel and biofuels in compression ignition engines (known as diesel engines). Sub-topic 1: Study on the combustion characteristics of diesel/methyl stearate in a diesel engine The effect of diesel/ methyl stearate blending ratio and the combustion catalyst on the fuel efficiency, ignition delay and heat release rates will be investigated under different engine speed and load conditions. Sub-topic 2: Study on the gaseous emissions and characteristics of soot particles from the combustion of diesel/ methyl stearate in a diesel engine The effect of diesel/ methyl stearate blending ratio and the combustion catalyst on the emissions of smoke, NOx, CO and unburned hydrocarbons, as well as on the physical and chemical characteristics of soot particles will be investigated under different engine speed and load conditions.
