The preparation of methyl esters of used frying oil, available as waste from restaurants and households, is described. Fuel specifications of this fuel are given, and values for gaseous (HC, CO, NO x ) and particulate emissions, measured with a vehicle powered by a turbocharged, direct injection diesel engine, are shown. The ester fuel shows slightly lower HC and CO emissions but increased NO x values compared with reference US‐2D fuel. The particulate emissions, however, are significantly lower with used frying oil. Preliminary results of an engine road test are described.
