Reliance of the fossil fuels throughout the world in industrial sector and transportation make these resources become highly in demand nowadays. As a result, the price of these fossil fuels becomes higher due to their limited condition. Diesel and coal may appear to be very practical fossil fuels however they are ecological threatening. The emission discharge from the fossil fuels is the purpose for unnatural weather change and ozone pulverization.
Therefore, government all over the world are forcing the utilization of biodiesel which can reduce the emission that been discharge in the air. Biodiesel which are experimental changed from vegetable oils are primary substitution for original diesel fuels. However, experimental testing by using fully vegetables oil in diesel engines was conduct and the result appear to be failed because of it higher viscosity. Thus, to produce an effective biodiesel, the combination of vegetables oils and diesel oil must follow the ratios that have been made and the process of combustion and fuel injection must completely understand.
In this research, rice bran and sunflower were selected as the main substitute to be biodiesel because it was easier to find in the markets due to the popularity of these two sources as cooking oils.
In Malaysia the probability to used rice bran oil is higher. This is because the economic growth of paddy rice in Malaysia roughly estimated more than 2.5 million tons which is it can produce more than 250000 MT rice bran. Furthermore, rice bran also consist 60% of nutritive value which is good and eco-friendly to our environment.

Meanwhile, sunflower grab incredible potential for balancing oil diesel utilize, particularly at the homestead scale. This is because sunflower yields well in various situation, and can be developed effortlessly and productively in a small and larger homestead. Other than have a high grade cooking oil, sunflower also share the same oil composition with other vegetable oil such as soy and safflower. Due to this causes, sunflower oil may be used as biodiesel in order to get the same properties as soy biodiesel.
