Project Details
Description
Funded by the EPSRC in 2001, a comprehensive experimental programme was proposed to enable the fundamental study of the effects of exhaust gas recirculation (EGR) as an effective means by which advanced Diesel combustion systems can best provide the solution to stringent, future engine emissions legislation.
Light emission from excited molecular and free radical states induced by a high energy laser source can be used to provide both quantitative and qualitative data on chemical concentrations and particulate formation in regions developing from the combustion reaction zone and early flame kernel.
Studies of fluorescence, incandescence, light scattering and local fuel concentration with exciplex dopants, were used to assess the diluent effect of varying percentages of cold and fresh EGR. The role of EGR on both pilot and post fuel injection and the NOX against noise trade-off can thus be best assessed in isolation, or as a collective contribution to the emerging technologies of diesel combustion system after treatments such as SCR.
