The results about selected ion flow tube/mass spectrometry (SIFT/MS) study of the different compounds in petrol and diesel vapor''''s using H3O+, NO+ as the precursor ions are reported. We assume both petrol and diesel are made up of CHs, including alkanes (CnH2n+2), alkenes or cyclokanes (CnH2n) alkynes or dienes (CnH2n-2) and aromatic hydrocarbons (CnH2n-6). Among these compounds, the alkanes are the predominant species both in diesel and petrol vapors; The most obvious difference between petrol and diesel vapor is. the presence of a greater abundance of long chain aliphatic CHs in the diesel vapor. In this paper, the mass spectra of petrol vapor using the precursors of the H3O+, NO+ and the quantitative analysis results of, the compounds in the petrol and diesel vapors are also presented.
