ACTUATING MECHANISM OF ELECTRONIC SYSTEM OF IN-LINE DIESEL ENGINE CONTROL IN HIGH-PRESSURE FUEL PUMP Russian patent published in 2009 - IPC F02D1/00 

FIELD: engines and pumps.

SUBSTANCE: invention is related to propulsion engineering, in particular to controllers of fuel supply into cylinders of diesel internal combustion engine. Actuating mechanism of electronic system of in-line diesel engine control in high-pressure fuel pump (HPFP) comprises controller body rigidly fixed in HPFP body on the side, which is opposite to drive coupling, and multipolar rotary electromagnet installed in controller body, as well as transfer lever of HPFP regulating rack drive, which is rigidly fixed in axis of rotary electromagnet, and also return spring of transfer lever. Rotary electromagnet is rigidly fixed in controller body with perpendicular direction of axis to plane that passes through axes of cam shaft and injection sections of HPFP. Transfer lever is hingedly connected to traction rod of HPFP regulating rack, which is adjusted in length with the help of helical pair and spacer spring, and traction rod connection to regulating rack is also arranged as hinged.

EFFECT: invention provides for compactness, fast and adequate reaction to real changes of traffic conditions with optimal fuel consumption and normative emission of spent gases into atmosphere.
