The analysis of the types of loads and factors of the service's life decreasing for sealing precision interface of the nozzle from diesel engine injector

The analysis of the thermo-dynamic, gas-dynamic and hydro-mechanic types of loads is performed for a nozzle of a diesel engine injector. Furthermore the estimation of the influence of mentioned factors to the level of thermal and mechanical condition for sealing precision interface are shown. The analysis of the reasons of wear and a decreasing of the service life for the sealing precision interface of the nozzle is presented.
