Ovcharov O. Reduction of carcinogenic emission at exhaust gas of car petrol engines.

The thesis is devoted to solution of technological problem concerned studying, analysis, and means option in order to reduce the cancinogenity of ICE WGs. An method for evaluation of the total cancinogenity of ICE WGs according to European stadart ecological examination of car on a bench with running drums. Full-flow combined systems for trapping C20H12 (BP) off ICE WGs are improved and introduced. An method for quantitative rating is worked through. It is shown that BP is a reliable indicator of cancinogenity of ICE WGs. High efficiency of reduction of ICE cancinogenity while gas fuel, fore-chamber-flame ignition of petrol-gas mixture, and thermo-catalitic neitralization system are used is shown. Rational ways of WG cancinogenity reduction of car ICEs are stated.
