摘要

Background: Biofuels are one of the promising alternative fuel sources for automobiles.The use of biofuels in combustion engines of automobiles showed many advantages and disadvantages.In this study, the advantages and disadvantages of using biofuels in internal combustionengines are reviewed and summarized based on early studies. Biofuels can offer favorable well-towheelCO2 balance in our environment and improve engine power and efficiency. Oxygen contentsin biofuels also provide advantages for the fuel combustion. However, biofuels, also showed somedisadvantages, like corrosiveness to engine systems and low heating values of biofuels. Boiling temperature,absorption with water, vapor toxicity, and autoignition of biofuels showed advantages forsome types and drawbacks for others.
