Biofuels are expanding continuously in global market as one of renewable options to replace fossil fuels. Biodiesel is the most commonly used biofuel that can be blended into conventional diesels in any proportion. However, higher biodiesel blends may cause problems. One of its problems is precipitation formation arise from biodiesel may clog fuel filter at low temperature. This study focuses on fuel and environment factors on biodiesel precipitation and their influence degree on fuel filter clogging. The results indicate that monoglycerides and temperature have strong correlation with precipitate weight. Moreover, quantitative effect of precipitate weight on filter clogging was clarified.
