Addressing the balance between consumption and production of various types of motor fuels can be achieved by improving refining and optimizing the quality of motor fuels. The first trend is the general line of development of the petroleum industry and involves the development of flexible technological schemes of deep oil refining on the basis of thermo catalytic processing of petroleum residues. The second direction is connected with the change of the quality of fuels that are holding the increase in their selection of oil. Efficiency optimization of motor fuel quality will be justified, if not cause significant additional costs in the establishment and operation of engines and will not lead to deterioration in their fuel economy compared to the possible expansion of production resources. In this regard, under the optimized quality of motor fuels should be understood as providing an economically and technically justified demands of consumers for the volume and structure of production of motor fuels at the same level of quality, which is characterized by minimal national economic costs (reduced and energy) in their production and use. Should also be taken into account eco-efficiency to optimize the quality, relevance of which increases with pollution.
Many of the requirements for the quality of motor fuels - the density, viscosity, specific heat of combustion, fractional, elemental and hydrocarbon composition - are linked. For each parameter must be found an optimum level, interconnected with the set of all physical, chemical and operational properties of commercial motor vehicles.
The most important qualitative characteristic of gasoline is the octane number. Increasing the compression ratio in engines can increase their capacity and efficiency, reduce fuel consumption. But the increase in cardinality and economic performance engine is only possible by increasing the octane number of gasoline.
