In modern fuel combustion theories, the effect of various energy fields on fuel components involved in the combustion process is considered insufficiently. This effect, at given parameters of the fuel combustion process, results in the significant improvement of the quality characteristics of the process.

It is known that the technical characteristics and economical efficiency of internal-combustion engines, jet-propulsion engines operating on liquid fuel, turbojet engines, and  turbo-propeller engines depend on the quality of fuel combustion.

On the basis of the developed theory of action of certain energy fields on fuel before the fuel enters the engine combustion chamber, and considering the test data obtained in this connection, it may be concluded that the properly provided action of energy fields on the fuel components involved in the fuel combustion process allows the combustion process to be improved and, as a result, the coefficient of efficiency and economical efficiency (by up to 50 percent) of internal-combustion engines to be enhanced, environmental characteristic to be improved due to more complete fuel combustion, and the amount of incompletely burned-out hydrocarbons in exhaust gases of engines to be reduced.

The developed method of action of energy fields on the combustion process is presented as know-how and belongs to the QUALITY 4 YOU doo. (Belgrade, Serbia).
