Performance and Emission Characteristics of a Diesel-LPG Duel Fuel in Greeves Engine

M. Yuvaraj, M SenthamilSelvan, Stanly Wilson Louis, V Kayalvizhi


The main perspective of this paper is to analysis the performance and emission of the diesel engine where diesel is used as primary fuel and LPG is used as subsidiary fuel. In this LPG is attached to the inlet manifold of the engine in which LPG combines with the molecules of oxygen and it barges into the combustion chamber of the engine. Inside this combustion chamber, diesel is injected by an injector during the end of the compression stroke, after this atomization of the fuel takes place eloquently. By this immediately after the combustion of the fuel, heavy loads of power is produced inside the combustion chamber and this is followed by the liberation of exhaust gases such as Hydrocarbon (HC), Nitric oxide (NOx), Carbon monoxide (CO), Carbon dioxide (Co2), Oxygen (O2) etc., As a result of this experiment the emission and the specific fuel consumption of the engine was reduced and brake thermal efficiency was increased. Thus this experiment shows that using LPG as an additive fuel with diesel which is an injecting fuel will increase the efficiency with respect to the traditional diesel fuel operation mode in the diesel engine.
