The selected characteristics of fuel injection in the systems of marine combusion engine common rail type

The injection Systems of Common Rail type are becoming widely used in marine combustion engines. The research and development of these systems aims to multi-criterial optimization of the injection process. The authors of the paper present the results of tests on the fuel supply system of the common-rail marine engine. The study was conducted on a special laboratory stand for nominal, average and minimum engine speed. For the analysis were accepted three variants of fuel supply – a single dose, two-piece dose and three-piece dose. There were presented the received characteristics of injection and discussed their most important aspects.
