International legislation has recently stressed the development and use of environmentally clean automotive fuels. Stiffening of the environmental requirements for auto engines is forcing auto manufacturers all over the world to search for totally new technical solutions to satisfy the approved standards. Since modern machines are becoming increasingly more complicated and their output power is increasing, the composition of the exhaust gases is being increasingly severely regulated. Fuel conservation is now an important goal. The market and environmental protection are the driving force of this process. Of the many ideas, the development of catalytic converters has become the most realistic and effective measure for reducing the toxicity of exhaust gases. Equipping cars with these systems allows “detoxifying” up to 90% of the toxic substances. However, for efficient operation of the catalytic converter, the vehicle must be equipped with a forced fuel injection system, since an ordinary carburetor does not ensure the stable optimum composition of the mixture [1]. Replacing carburetors by injection fuel feed and distribution systems in gasoline engines was an unconditional achievement in automobile manufacture: fuel combustion improved and as a result, the power of the car increased, while fuel consumption and exhaust gas toxicity simultaneously decreased. Autos began to be manufactured with forced fuel injection in 1980. Over 70% of the engines in current foreign automobiles have been equipped with fuel injectors since 1990. The approved Euro-3 and Euro-4 standards for the toxicity of emissions required further improvement in automotive engine designs. Among the other technical innovations, we note the heated converter and the exhaust gas recirculation system. The next step, beginning in 2000, was the mandatory use of onboard diagnostic systems for gasoline engines. They can control vehicle emissions during their entire lifetime. The progress in automotive engine manufacture is constantly imposing new requirements on fuel quality. Environmental protection laws all over the world provide for switching to environmental ly clean vehicles which must run on the corresponding fuels [2]. Ensuring the environmental characteristics of the automobile and preserving them during use are directly dependent on the use of high-quality motor fuels. For this reason, auto manufacturers are turning directly to fuel manufacturers and are instituting joint programs to solve the environmental problems. Base gasoline consisting of equal parts of naphtha from primary distillation and catalytic reforming or cracking with the addition of a high-octane component is usually used for production of standard gasoline [3]. The antiknock effectiveness of the high-octane component is a function of a multitude of factors. The ability of
