FIELD: mechanical engineering; gasoline internal combustion engines. ^ SUBSTANCE: invention can be used for restoring characteristics of electromagnetic nozzle of injection system. According to proposed method, contact of washing liquid with inner spaces of nozzles is provided with simultaneous action onto washing solution with signals of definite frequency and cleaning of nozzles said under said conditions for definite time. Washing solution is delivered through nozzles under pressure, and pulses of definite frequency at fixed voltage are periodically fed to coils of nozzles to provide vibration of valve needle, and then capacity of nozzle and nonuniformity of delivery of standard fuel by nozzles are determined. ^ EFFECT: possibility to restore power and economy characteristics of engine. ^ 6 cl, 1 dwg |
