Clean Combustion of Diesel

There are two primary routes for the reduction of diesel engine emissions. One is through the improvement of the engine design. The other is to formulate the diesel fuel by increasing the cetane number and improved properties. This project focused upon the development of diesel additives, so as to improve diesel ignition and combustion performance. In this project, we aim to develop a process and novel additives that are comparable to diesel fuel but that also increase the H/C or O/C ratios.
Diesel engines have a higher fuel efficiency and economy, but the emission of carbon soot and NOx are major environmental concerns. The need for improving diesel combustion efficiency has never been more evident than in this environmentally driven world in the on-going dieselization process. It has been shown that increasing H/C or O/C ratios of diesel can help to reduce soot emission. This project examines the use of additives for example hydrogen or oxygen containing soluble or nano particle additives. Others may include oxygen containing liquids to improve combustion efficiency. It is expected that through the use of these additives that the emission of sulphur, nitrogen and carbon containing by-products are reduced.
