PROPERTIES OF GASOLINES FOR VEHICLES AND THEIR ENVIRONMENTAL-IMPACT

Legislative measures limiting the emissions from combustion of vehicle -engine gasolines are surveyed. The knowledge concerning effects of ph ysico-chemical properties of gasolines on the formation of the emissio ns and the use of catalytic convertors for emission elimination or red uction is also reviewed. The problems of atmosphere contamination with gasoline evaporated from the fuel system during vehicle operation and standing and during gasolines handling is discussed and the methods r educing this contamination are mentioned.
