An Experimental Investigation of the Effect of Traditional Enhancement on Spark Ignition Engine Performance

Abstract

An Experimental investigation of the effect of traditional additive on the performance of spark ignition engine ,by use three traditional types, which were used as additive (gasoline additive, Gema and T-max )that were added to pure fuel as a volumetric ratio(1/6, 1/7.1 and1/8) respectively . The tests were done for pure blending fuel at various speed revolution (600-3000 RPM). The results showed that the engine performance increase with using traditional additive, the brake power increases by (23%,18% ,and 12.6%) at using gasoline blending(T-max, Gema & gasoline additive) respectively as combined with pure fuel, also increasing the brake thermal efficiency, that maximum ( bth) for (T-max) approximately about (8%) and minimum for (gasoline additive) about (3.7%). The study showed that enhancement in the brake specific fuel consumption for (T-max ,Gema, & gasoline additive) by (5%,2%,and 1%) respectively compared for pure fuel. from the results the traditional additive T-max type given best performance for I.C.E.
