A comparative study of engine performance and pollutant formation during diesel and dimethyl ether injection
Compression ignition engines are likely to remain a dominant prime mover for the foreseeable future, particularly in heavy duty road transport, sea transport and power generation. Dimethyl ether (DME) is one proposed zero emission fuel for compression ignition engines that can be made using renewable energy. DME also possesses several properties that makes it superior to diesel in terms of both engine performance and emissions.
However, several processes by which pollutants are formed in compression ignition engines are still poorly understood. This is particularly the case for particulate matter (PM) and oxides of nitrogen (NOx) with alternative fuels such as DME. This project will therefore undertake a comparative experimental and numerical study of the formation of PM and NOx in diesel and DME sprays using a Constant Volume Chamber (CVC) and Large Eddy Simulations (LES).
