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

Abstract

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.
