As a potential means of offsetting diesel fuel usage and reducing the environmental impact of used tyres, this study investigates the NO x emissions of a modern commercial passenger vehicle run on a blend of diesel and tyre pyrolysis oil (TPO). The test vehicle was driven on a route representative of the driving expected by a courier. Vehicle drivability with the TPO/diesel blend, compared to neat diesel, was not reported to be perceived differently by the automotive industry experienced driver. Additionally, the NO x emissions were comparable between the neat diesel trip and those run on the blend of TPO/diesel. Interestingly, the results showed that short transients had a substantive impact on aggregate NO x emissions—making conclusive on-road comparisons between fuels difficult. Despite this, the data collected for this study indicate that there is no substantive NO x emissions degradation when running the TPO/diesel blend.
