Abstract— Studies reveal that Acetylene gas produced from lime stone (CaCO3) is renewable in nature and exhibits SImilar properties to those of hydrogen. An experimental investigation has been carried out on a SIngle cylinder, direct injection (DI), and Spark ignition (SI) engine tested with pure petrol and petrol – Acetylene dual fuel mode with diethyl ether (DEE) as oxygenated additive. Experiments were conducted to study the performance characteristics of DI petrol engine in dual fuel mode by aspirating Acetylene gas in the inlet manifold, with petrol- diethyl ether blends (DEE) as an ignition source. Fixed quantity of Acetylene gas was aspirated and Blend of diethyl ether with petrol (DEE10, DEE20and DEE30) was taken and then readings were taken at various loads. From the detailed study it has been concluded that the blending ratio of DEE20 gives better performance. Dual fuel operation along with addition of diethyl ether resulted in higher thermal efficiency when compared to neat petrol operation. Acetylene aspiration reduces smoke and exhaust temperature.
