The worry on the risk of conventional diesel fuel's depletion in the next few years has bring arises in the interest of biodiesel utilization. In addition, it is proved that biodiesel is capable of cleaner combustion compared to conventional diesel, mainly due to its oxygen contents. Biodiesel is an oxygenated diesel fuel made from vegetable oils or animal fats by conversion of the triglyceride fats to esters via transesterification. Unlike biodiesel, usage of energy from fossil fuel leads to many problems related to environment due to their emission characteristics. Biodiesel is the solution of the problem, as they are basically biodegradable, non-toxic and a form of renewable energy. Unfortunately, most notable negative side of biodiesel is increased nitrogen oxides emission. In this project, transesterification was used, with potassium hydroxide as catalyst to convert three different types of cooking oil which are palm oil, canola oil and coconut oil into biodiesel. These pure biodiesels were then blended with conventional diesel and tested using diesel engine. Main scope of this project is to analyze the carbon monoxide and nitrogen oxide emissions. Observation on the results of flue gas analyzer testing shows that carbon monoxide is reduced but nitrogen oxides are increased with biodiesel usage. iii
