Abstract

Contamination of atmosphere by the toxic substances of exhaust gases of motor-vehicle and tractor technique is an extraordinarily important problem of present time. There are quite a bit methods of reduction of extrass of harmful substances of cars. But the choice of certain method comes true usually intuitively. The method of choice of technology of modernisation of car is offered on the basis of approach of the systems and multicriterion optimization on the criteria of manufacturability, ecological safety and economy. Possibility of improvement of ecological indexes of car is in-process examined due to the use of alternative agile fuels. According to the worked out method the useing of petrol, condensated petroleum gas and natural gas is certain in case of their application in a car GAZ – 3307. The criterion of manufacturability is determined by the evaluation of operating indexes of car by the method of pair comparisons. The criterion of ecological safety is determined as a relation of total toxicness of exhaust gases during a thruster-on on the different types of fuels to the normative index of total toxicness. For comparison of toxicness of exhaust gases of car the total specific extrass of the rationed harmful substances with a serial and modernized engine, resulted to the oxide of carbon, were determined. The total amount of harmful extrass is for petrol 2.15 times higher and for condensated petroleum gas 1.57 times higher as for natural gas. The criterion of economy is determined taking into account reduction to the prime price of transportations and size of charges on modernisation of car. The global criterion of choice of optimal method is determined by the additive rolling up of partial criterions. World-modeling of the car functioning allowed to choose the best accessible technologies of modernisation with the aim to improve their ecological indexes, to optimize the parameters of the operating system "technology - engine - transport vehicle" according to the chosen criteria. Certainly, that the most value of global criterion has using of natural gas as an agile fuel in the truck mainly used in municipal terms.

Key words: alternative fuels, ecological indexes, approach of the systems, multicriterion optimization.
