Assessment of bus exhaust emissions from tallow methyl ester biodiesel blends
Research and reports
1 March 2009
This report documents findings of research on two in-service buses fuelled with tallow
methyl ester (TME) biodiesel blends of 20% (B20) and 40% (B40) TME in 50ppm
sulphur automotive diesel fuel (ADF) referred to as the 50ppm fuel. The same batch of
50ppm fuel was used as the reference fuel for the experiments. This programme was
conducted as a postgraduate research project and in co-operation with the Auckland
Regional Council (ARC), BP Oil New Zealand Limited, the Energy Efficiency and
Conservation Authority (EECA) and the Energy and Fuels Research Unit (EFRU) of the
University of Auckland.
