Rotating/Gliding arc gas discharge is known as a suitable application for plasma aided combustion (PAC). In this study, effects of rotating arc discharge on combustion of diesel and biodiesel fuel are investigated. The main focus of the experiment is to determine the effectiveness of rotating-arc in enhancing combustion performance. The first stage of the burner is designed for the fuel-air mixture to interact with the rotating arc at fuel-rich condition. The second stage of the burner is the main combustion section to make the mixture at overall fuel-lean condition and properly hold the flame inside the combustion chamber. As a result, lean flammability limit determined by equivalence ratio at lean blowout is found to be extended quite a bit when the arc is on. FTIR (Fourier Transform Infrared Spectroscopy) measurements of exhaust gas show that both CO and CO2 concentration become higher and O 2 concentration lower for overall fuel-lean combustion with plasma on. Based on the results of level of total carbon oxidation, combustion efficiency is slightly higher with plasma than without plasma. Slightly more NO is produced when the arc is at present for a fixed equivalence ratio. However, with the extension of lean flammability condition achieved by plasma-assisted combustion the minimum NO is produced for PAC case. The increase of reactant temperature due to direct heat transfer from the arc to the surrounding and partial oxidation (exothermal) can mainly account for the observed enhancement of combustion for the PAC.
