| Popis: | The combustion of hydrocarbon fuels in the combustion chambers of diesel engines is preceded by processes of both physical and chemical transformations. The nature of the chemical transformations and their effect on the workflow are usually not taken into account. Meanwhile, their role in ensuring the efficiency of the workflow is very large. Chemical transformations in hydrocarbon fuels in combustion chambers cause the appearance of products capable of self-ignition under the influence of temperatures and pressures arising at the end of the compression stroke. The chain of these transformations ends with the formation of soot particles, the burning of which with abundant heat release in the form of radiant energy has a significant effect on the value of the indicator efficiency. The content and ways of influencing chemical transformations in fuel are considered, as well as the use of these transformations in increasing the combustion efficiency of fuels and increasing the indicator efficiency. |
