Effect of combustion saturated and unsaturated fatty acids pure vegetable oil for noise
Keywords:
vegetable oil, saturated, noise, combustion, open trayAbstract
The steady increase in fossil fuel prices and the dependence on oil from producing countries to searched fuel alternatives to combustion engines. Vegetable oil is one of the renewable sources of energy that can be used. Vegetable oils also have the advantage of containing little to nitrogen. Radiated noise from diesel engines can be broken down into mechanical noise and combustion noise. The sound of combustion is distinguished into direct combustion noise and indirect combustion noise. The purpose of this researched is to know the effect of the chemical composition of variated pure vegetable oils to the noise generated in the combustion process. The study was conducted in an open tray which is heated by a heating element, which is filled with vegetable oil and then burned and given airflow variatiated velocity 39, 49 and 55 cm/s, the combustion is recorded using a softwere steinberg wavelab 6 (spectrum analyzer). Combustion of pure vegetable oil (jatropha curcas lin, ceiba petandra, catton seed, coconut) produced the highest noise level is on jatropha oil (-81 dB) followed ceiba petandra oil (-90 dB), catton oil seed oil (-99 dB) and Coconut oil (-108 dB). The study concluded that the content of unsaturated fatty acids one double bond (monounsaturated fatty acids) in the hydrocarbon chain thus facilitate reacted with oxygen and flammable.
