Results from the study are summarised in Table 1. The emissions rate in g/kg is obtained directly from measurements recorded by the portable emissions sampler. This shows the grams of particulate emissions per kilogram of fuel burned, where the fuel weight is expressed on a dry weight basis. This is the same as used in AS/NZS 4013 for laboratory measurements of particulate emissions.
