Figure Legend:
Mass spectra of exhaust gas samples from three engines (CJ6108A, CFM56-3B1, and RB E4-B) and two lubrication oils (Mobil II and Air BP). Mass spectra of the lubrication oils were obtained by aerosolizing oil samples obtained from the engines (Mobil II from the RB E4-B and Air BP from CFM56-3B1). Characteristic m/z signals are highlighted for easy reference. The m/z=27/29, 41/43, 55/57 series is due to hydrocarbons. The m/z=85, 113, 127 series is likely due to the synthetic esters in lubrication oil.
