Article discusses issues concerning researching electromagnetic fuel injectors. These fuel system is using in automobiles all the time. Bosch Company declined piezoelectric fuel injectors and reverted to electromagnetic. There are known Denso, Delphi and Bosch electromagnetic fuel injectors. Article describes how to diagnose and repair it. Denso and Bosch fuel injectors have almost the same construction. These objects have very similar repair technology. Despite Denso fuel injectors has not manufacturer official repair technology it is possibility to regenerate it because there are tools and many spare parts available on the market. Article discusses construction and operation presented fuel injectors. There has been shown diagnostic parameters and how to analysis it. Researches have been made in laboratory handle; to research and repair Diesel injection systems. Article describes construction, operating testing and repairing of electromagnetic fuel injectors. The aim of the article is to present the possibilities of researching and repairing electromagnetic fuel injectors. The fuel unit injector testing and repair process is carried out. The tests were conducted in a specialist laboratory where fuel injectors, fuel unit injectors and fuel injection pumps are being regenerated. The setting of the opening pressure of fuel unit injector is a very important stage because it affects the volume of injection doses. The opening pressure of fuel unit injector should amount to 28 MPa. F
