Brail'chuk A. Operating method development of toxicity of decrease of carburettor vehicles at the expenseultrasonic homogenizer application

The object of research is limitation possibility of harmful substances formation in exhaust gases of a carburettor vehicle in different operating conditions. The aim of the research is as follows theoretical and experimental study of the effective operating method application of toxicity decrease and fuel saving rise of carburettor vehicles. Methods of the research - analytical and experimental methods of research are used in this work. Results of theoretical research are compared with data obtained in road and stand experiments and results of operating tests. Diagnostic and measuring equipment PDS-L (gas analyzers, flowmeters) has been used. New theoretical and practical results - the new operating method of toxicity decrease of exhaust gases of carburettor vehicles is proposed and it allows to decrease CO and CmHn concentration in 1,5:2 times and it also secures homogenizers together with recirculation of exhaust gases decreases nitrogen oxide by 50:60% in part load and 20-30% in full load: in the fu ll load without impairment of factors of the engine cycle; the new methods of the stand check of exhaust gases toxicity of vehicles with forced ignition have been worked out; the device cost is twice lower, than catalytic converters cost. The level of introduction - by decision of local bodies more than 300 homogenizers have been mounted on taxi in taxi fleets and it allowed to decrease the line rate of the fuel consumption by 5%. The field of application is vehicle operation.
