An additional expansion of fuel from the area under the nozzle needle seat into the combustion space considerably influences HC, CO and PM formation. The mentioned expansion can be limited by the injection process optimization. One element of the fuel system playing a significant role in the injection process - its hydrodynamics, is a delivery valve of the injection pump fulfilling also the role of relieving the high-pressure area. The paper deals with hydrodynamics of the injection equipment with a multi-cylinder injection pump. Achieved results serve as input parameters for a subsequent model and experimental solution of the influence of observed parameters on economic and ecological parameters of diesel engines.
