Modern diesel engines are equipped with a Common Rail injection system. The injector is probably the most complex component in this system. To facilitate Common Rail system testing or research it can be individually mounted, separate from the engine, on an experimental stand. In this way, the shape and characteristics of the fuel jet can be analyzed more easily. Viewing and analyzing the electrical signal was done in the paper through the AVL Indicom program. In the paper is analyzed the control signal of an electromagnetic injector, during injection of a quantity of fuel from 2 to 40 mg, with differed strategy injection: one, two or three injections.
