Abstract
This study provides insight into performance of internal combustion engines while using renewable fuels. Biogas and producer gas mix together with biodiesel was supplied to a spark ignition dual fuel engine and its performance was analysed. The engine was also operated on biodiesel alone in order to draw comparison in the performance on both the single fuel and dual fuel mode. The brake thermal efficiency (BTE) in mixed fuel mode was obtained 61.4% lower in a biodiesel-producer gas mode and 69.13% lower in a biodiesel-biogas-producer gas mode in comparison with diesel mode at 5 kW load. The brake specific energy consumption (BSEC) for biodiesel-biogas-producer gas mode at 6 kW load was higher by 164.80% and 87%, respectively, than for diesel operation. This work was carried out with the objective to explore the potential for utilization of waste agro residues as biofuels for dual fuel engines, used so prevalently in rural areas.
