Abstract

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.
