FUEL SYSTEM OF INTERNAL COMBUSTION ENGINE Russian patent published in 2002 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: invention relates to fuel equipment of internal combustion engines. Said fuel system has control unit, electrically controlled nozzles with fuel feed elements and high pressure fuel pump. Control unit is made in form of rotor mechanically coupled with engine shaft and provided with contact connected with control voltage source. Rotor contact can come into action with two rows of contacts when rotor is rotating, these contacts being uniformly spaced over circumference axially relative to rotor. Contacts of one row are fixed and electrically connected with like poles of corresponding nozzles, contacts of other row are interconnected by common current conductor, for instance, in form of ring, for angular displacement relative to fixed contacts. Contacts of said row are electrically connected with ground. EFFECT: simplified design, reduced labour input in manufacture, enlarged operating capabilities of system. 3 cl, 1 dwg
