Performance of Four Stroke One Cylinder IC Engine with Dual Spark Plugs Using 94-100% Ethanol

Iis Siti Aisyah, Wiki Setiyoadi, Suwarsono .


Problems related to depleted fossil fuel reserve and worsened air quality in the earth needs to be solved. One of the solutions is using ethanol, an alternative fuel produced from the plants. A research was conducted to identify the feasibility of ethanol 94-100% as fuel for one cylinder IC engine of 110cc Yamaha LM-5. In the research, the combustion condition was set to stoichiometric ethanol combustion. Engine rotational speed was 1500 – 4000 rpm. The change made into the engine is adding one more spark plug to become dual spark plugs configurations. The results showed that dual spark plugs gives more efficient combustion compared with single spark plug for combustion of ethanol 94-100%. The emission of exhaust gas, fuel consumption, torque and power were analyzed.
