Article discusses issues concerning diagnosing and researching fuel unit injectors (UI). This fuel system has been taken off in automobiles but the problems with diagnosing and research is still actually. Motorized vehicles with fuel unit injector system were manufactured until 2010 but lorries are still producing. Only one automotive concern VW put in this system to motorized vehicles in Europe. The 1.9 TDI engines have PDE 1 (UI) and 1.4 TDI, 2.0 TDI engines have PDE 2 (UI). Unit injector is device which main tasks are spray and distribute fuel in combustion chamber of Diesel engine. Unit fuel injector is built with three sections: fuel injection nozzle complex, electromagnet unit and pump part. Injection nozzle complex is common mechanical one spring injector. That research is on check and eventually adjusts open pressure. Electromagnet units are non-dismantle and non-repair, but there is possibility dismantle and clean it. Electromagnet unit affects injection dosages and module BIP (being of injection period) unit fuel injection. The task of pump part is fuel damming until demanding values. The pump part makes up piston with and main body, spring and protect flat piece of metal. Theoretically, also this element is non-repair. Main unit fuel injector work parameters are injection dosages values and signal BIP. During fuel unit injectors research checks injection dosages with varies settings (rotation speed, injection time). These parameters are similar to engine work on idle speed (idle speed dosage), pilot dosage, middle and full load dosage.
