Blending lignin-derived oxygenate in enhanced multi-component diesel fuel for improved emissions

Experiments were conducted on a single-cylinder diesel engine to ascertain prospective improvements in engine performance and exhaust emissions with various blends of additised and non-additised diesel fuels. Two fuel additives, cyclic peroxide (3,6,9-trimethyl-3,6,9-triethyl-1,2,4,5,7,8-hexaoxacyclononane) and cyclohexanol are blended in diesel and or synthetic diesel and there effects on fuel properties, combustion characteristics and emissions were studied. The cyclic peroxide was chosen to be studied for its potential to increase cetane number and reduce engine out emissions when used in multicomponent blends. Its capability as a cetane-enhancer was proven when used at various concentrations in multiple diesel-like fuel blends.
