An experimental study is conducted on the utilization of the inlet ethanol injection technique in order hellcat spark plugs to evaluate its impact on the performance of a two-shaft T200D mini-gas turbine engine.The maximum degradation recorded in power output was 32.8% at the climate temperature of 45oC.Nevertheless, at that temperature, adding ethanol with Eth/LPG ratio of 20% by volume brought an enhancement in power output of 19.2% compared to normal LPG run.

SFC of the dual-fuel engine ranked a off white 5000 puffs level of 22% higher than that with pure LPG consumption.The overall efficiency suffered a maximum reduction of 14.4% with Eth/LPG fuel ratio of 20%, but when the loading was raised beyond 70% of the engine full load; the efficiency of dual-fuel engine excelled the normal LPG engine by 3.1% at the corresponding Eth/LPG ratio maintaining a power turbine speed of 12000 rpm.
