Environmental pollution cost analyses of a compression ignition diesel engine fuelled with tire pyrolytic oil-diesel blends

Abstract

This paper represents the environmental pollution cost analysis of a single-cylinder, four-stroke, naturally aspirated, compression ignition diesel engine fuelled with tire pyrolytic oil (TPO)-diesel blends. TPO-diesel blends were prepared as 10 vol.% TPO + 90 vol.% diesel (TPO10D90), 30 vol.% TPO + 70 vol.% diesel (TPO30D70) and 50 vol.% TPO + 50 vol.% diesel (TPO50D50) blends. The experiments were con-ducted on test engine loads of 3 Nm, 6 Nm, 9 Nm and 12 m and on con-stant crankshaft speed of 2000 rpm. It was found that TPO10D90 had bet-ter performance compared to neat diesel and other blends considered in this study in terms of environmental pollution cost analysis. As a result, at engine load of 3 Nm, the specific environmental pollution costs of neat diesel and TPO10D90 were obtained to be 0.05361 $/kWh and 0.04724 $/kWh, respectively. It can be concluded that TPO-diesel blends having low TPO content can be used as alternative fuel for neat diesel in diesel engines in terms of environmental pollution cost analysis.
