Abstract
Diesel engines being self-contained power plants are the most promising energy
sources in transport from the point of view of saving natural resources. In order
to improve the fuel efficiency and power density of diesel engines for further
development of transport energy, requires using energy-saving technologies.
Such technologies to create diesel engines are based on a comprehensive
improvement and optimization of operating cycle and its comprising processes.
Special attention is paid to ensuring the effective combustion of fuel within the
constraints imposed by the emission of harmful substances in the exhausting
gases and the thermo-mechanical loaded parts.
In order to evidence-based selection, method of management of combustion
process on the basis of analysis of physical and chemical characteristics of
processes developed intracylinder refined mathematical model of combustion
of fuel in diesel engines.
The basis of determining efficiency of selection and management of
combustion process is a differentiated approach to the assessment of the control
actions. According to the results of computational and experimental synthesis
cycle in diesel engines, basic principles of fuel control combustion process were
developed.
Implementation of the developed guidelines and best management practices
during the combustion process of fuel improves technical level and
competitiveness of diesel engines, improves fuel efficiency by 5 ... 7%, reduces
thermo-mechanical loading, maximum temperature and pressure of gas in
