The working body of engines equipped with electronic fuel injection systems are electrovalve injectors (injectors). Structurally, the nozzles are made non-separable, and in the event of their failure, must be replaced.
The concentration of tar and sulfur (heavy hydrocarbon molecules) in gasoline depends on the technology for producing gasoline and its storage conditions. Getting into the fuel system, they accumulate on the hot walls of pipelines, contaminate the fuel injectors, which leads to a deterioration in the supply of gasoline, and therefore deterioration of traction. Even manufacturers of nozzles Bosch, Lucas, Nippon, Denso, GM recommend flushing the injector, for the purpose of prophylaxis, every 20 thousand km.
Module / Stand "Djinn" is intended for diagnostics and cleaning of the fuel supply channel of solenoid nozzles. The stand checks the resistance of the windings of the nozzles, the performance, the shape of the jet and the mechanical properties of the nozzles (reaction to short pulses).
