The criterion of development of processes of the self-organization of subsystems of the second level in tribosystems of diesel engine

The paper shows the possibilities of processes in the tribosystems of diesel engines, ensuring the development of self-organization processes in them. The criterion for the possibility of development of processes of the self-organization of subsystems of the second level shows that in a real irreversible process there is a decrease in the flow of mechanical energy. The paper considers three cases of the possibility of developing the processes of self-organization of subsystems of the second level on the example of the tribosystem crankshaft-insert for the operating conditions of a diesel engine 10D100. It was determined that in order to reduce the wear rate of the tribosystems of diesel engine it is necessary to provide the flow of the energy-mass transfer process on their contacting surfaces of friction by the gradients of chemical potentials and dislocation density of the interacting materials. The obtained expression is the criterion of possibility of development of processes of the self-organization of subsystems of the second level which indicates that the system would lose the stability, if the density of mobile dislocations or the wear rate of the tribosystems of diesel engine increases.

Automated summary

The paper explores the potential for self-organization processes in the tribosystems of diesel engines. It introduces a criterion for determining the possibility of self-organization processes in the second-level subsystems of the tribosystems, indicating a decrease in the flow of mechanical energy in real irreversible processes. The study considers three cases of self-organization process development in the crankshaft-insert tribosystem of a diesel engine 10D100. It concludes that in order to reduce wear rate, it is necessary to facilitate energy-mass transfer on contacting surfaces through gradients of chemical potentials and dislocation density.
