Only those components of these media that have significant vapour pressures at ambient temperatures were analysed and thus particulates were obviously not detected. These media have been analysed using the full scope of SIFT\u2010MS, i.e., with the three available precursor ions H\n                    <jats:sub>3<\/jats:sub>\n                    O\n                    <jats:sup>+<\/jats:sup>\n                    , NO\n                    <jats:sup>+<\/jats:sup>\n                    and O\n                    <jats:sub>2<\/jats:sub>\n                    <jats:sup>+<\/jats:sup>\n                    .

The O\n                    <jats:sub>2<\/jats:sub>\n                    <jats:sup>+<\/jats:sup>\n                    precursor ions are used to detect and quantify the large amount of nitric oxide present in the exhaust gases from both engine types. The petrol and diesel vapours consist almost exclusively of aliphatic alkanes, alkenes and alkynes (and dienes) and aromatic hydrocarbons. Some of these compounds appear in the exhaust gases together with several aldehydes, viz. formaldehyde, acetaldehyde, pentanal, pentenal (acrolein), butenal, and also methanol and ethanol. Acetone, nitric oxide and ammonia are also present, acetone and nitric oxide being much more abundant in the diesel exhaust gas than in the petrol exhaust gas. These data were obtained from samples collected into pre\u2010evacuated stainless steel vessels. Trapping of the volatile compounds from the gas samples is not required and analysis was completed a few minutes later. All the above compounds are detected simultaneously, which demonstrates the value of SIFT\u2010MS in this area of research.
