| Popis: | In a number of countries of the European Union the average age of vehicle fleet is over 15 years, and in the entire European Union vehicles are on average 11.1 years old. This means that the environmental parameters are largely determined by the technical condition of the current vehicle fleet and in particular by the condition of fuel systems operated over extended periods of time. The article examines the changes in the behaviour of electromagnetic nozzles of Common Rail fuel system as a result of irreversible wear and deformation, which in turn affects the hydraulic characteristics and controllable fuel supply parameters. The influence of the changes in the electromagnetic nozzle’s adjustable geometric clearances on the injected fuel and the dephasing of this process in relation to the moment of transmission of the control pulse are examined. An analysis of the impact of these phenomena on the work process development in terms of deterioration of the vehicle’s environmental characteristics is made. |
