摘要: Carbonaceous material associated with potent carcinogens such as 3-4 benz(a)pyrene (BaP) and other polynuclear aromatic (PNA) hydrocarbons constitutes by far the greatest part of particulate found in exhaust gases an internal combustion engine. The probable precursors carbon particles are radicals formed incomplete zone while their nucleation is made possible ions originating flame. Ion current instantaneous values were measured means a modified Langmuir's probe, thus calculating thickness speed flame engine cylinder. Relations between ion collected soot weight examined. Fuel quality additive influences over PNA formation obtained.
