Diesel Fuel Reformation by Piston Compression of Rich Mixture

Abstract

Diesel fuel reformations have been suggested to extend the operational ranges of premixed diesel combustion. In this research, the diesel fuel is reformatted by the piston compression of rich mixture in the reformation cylinder and the thermal conversion conditions of reformatted gases, hydrogen, carbon monoxide, and methane, were first investigated by the chemistry dynamics simulation (CHEMKIN pro). Based on the calculated results, the diesel engine was operated under the rich mixture conditions. Throughout this research, it was found that the composition of reformatted gas can be estimated by the maximum cylinder temperature.
