In the present work, effect of mixing gas venture (GV) on the performance of modified dual fuel (DF) engine with effective utilization of biodiesel and gaseous fuel combinations is reported. Biodiesel prepared jamun seed oil called jamun seed oil methyl ester (JAMUNME B100) and its B20 blend (JAMUNME B20) are used as pilot injected fuels while the biogas and compressed natural gas (CNG) are used as the inducted fuels in the modified DF engine. Hence, the present research focus on the enhancing of engine performance of DF engine fuelled with liquid and gaseous fuel combinations. Meanwhile, the effect of GV on modified DF engine performance is investigated. Higher brake thermal efficiency (BTE), lower carbon monoxide (CO), hydrocarbon (HC) and smoke emissions besides higher NOx emissions are observed with higher methane content gas. Combustion parameters such as ignition delay (ID), and peak pressure (PP) are analysed. The DF engine operated on renewable fuel combinations in DF mode can cover the way for partial substitution of fossil fuel along with reduction in greenhouse gas emissions. Increasing the number of orifices in GV will improve the gas-air mixing ratio.
