The assessment of performance and emissions characteristics of a CI engine running on waste tyre pyrolysis oil as an alternative fuel and its blends with diesel fuel

Abstract

The target of the present research is to examine the performance and emissions of waste tyre pyrolysis oil (WTPO) added into diesel fuel (DF) at different percentages in a compression-ignition (CI) engine. In the engine, tests were undertaken at four ranging loads (25%, 50%, 75%, and 100%) at 1500 rpm. The lower viscosity and energy content of WTPO compared to DF affected performance and emissions. Adding WTPO to DF increased fuel consumption, CO2, HC, and CO emissions, while reducing exhaust gas temperature (EGT). At the same load, HC emission increased by 13.3% as the fraction of WTPO in the blend ascended. While the EGT value of DF was 261oC at 25% load, this temperature dropped to 251oC for P40 fuel. When the load was 25%, the amount of CO2 emission ascended between DF and P40 fuel was 38.67%, while this increment reached 59.5% at the highest load. In the study, monthly CO2 emissions of fuel blends were calculated. In line with these calculations, it has been deemed environmentally appropriate to use end-of-life (EOL) tyres as fuel instead of scrapping them.
