“…Bosch injectors with the sensors: NCC and VCC EM (220 MPa) and piezo (250 MPa), heavy goods vehicles 270 MPa. There is also a research conducted on increasing that pressure to 300 MPa [11,22,33], regulating the course of fuel injection characteristic in storage systems of Common Rail type and optimizing the combustion chamber structure to the shape of injected fuel spouts [19,21,24,36]. For each construction of diesel engine, there are specific optimal combinations of injection and atomization characteristics combined with the air charge and combustion chamber shape, which provide the best operation parameters of the diesel engine [31].…”

The analysis of fuel injection processes in diesel engines showed the convergence of physical parameters affecting the mean diameter of the Sauter SMD (selected as a spray quality parameter) of the atomized fuel droplets and the parameters of the acoustic signal emission originating from the spring waves accompanying the atomization process. In experimental studies, the laser diffraction method was used to measure the atomization quality with the Malvern Spraytec device. For the acoustic signal recording and processing there was used the measurement set with a Fujicera 1045S sensor. The correlation between the values of the Sauter diameter and the energy of the acoustic signal has been obtained on the basis of which a method has been developed to assess the quality of fuel atomization in compression ignition engines by measuring the acoustic signal recorded during the fuel injection process

Annotation The analysis results of the action of various force factors that slows the hydraulic valve when fitting on the saddle are presented. Manifestations of inertia forces in a thin layer of liquid located in the gap between the valve and the seat immediately before the closing of the gap are shown. The components of inertia forces are distinguished, which differ in the mechanism of occurrence. The degree of their influence on the fitting process in relation to the viscosity forces is shown.
