description Bio-diesel is a clean-burning alternative fuel produced from renewable resources, such as vegetable oils or animal fats. The concentration of H has a great influence on the decomposition path of unsaturated fat mono-ester and the breakdown products in the process of reaction. The mechanism of adding antioxidant includes that H is supplied by the phenol hydroxyl (OH) end the transmission of free radical chain reaction. As a result, addition of antioxidants to bio-diesel could promote the reductive reactions and inhibit the oxidative reactions, which could increase the emission of soot, HC and CO but decrease NOX emission. The aim of the present study is to investigate engine performance and the exhaust emissions of a diesel engine using oxidative stabilized bio-diesel. Adding antioxidants can effectively reduce the NOx emissions of bio-diesel and have little influence on CO, HC, and soot emissions.
