Mel'nyk O. Efficiency improvement of petrol-gas mixtures in vechicles.

Principles of components rational ratio determination in "petrol-gas" mixture are elaborated. For principles realization mathematical model of automobile's movement was specified and experimental researches of internal combustion engine, equipped with universal feed system, feeding petrol, natural gas, "natural gas-petrol" different ratios mixtures were carried out. Transient processes of petrol feed transferring to "petrol-gas" mixture were experimentally investigated. Their quality were evaluated by mathematical model. System scheme improvement reduce mass hydrocarbons emissions on 17% per cycle. Rational ratio "perol-gas" for system with changeable fuel kind is 54% - petrol and 46% - natural gas..
