FUEL SUPPLY DEVICE TO CYLINDER OF INTERNAL COMBUSTION ENGINE Russian patent published in 2019 - IPC F02M31/02 F02M53/06 F02M61/00 F02M61/16 

FIELD: machine building.

SUBSTANCE: invention relates to fuel injection devices in a cylinder of an internal combustion engine. Device for fuel supply to engine cylinder, comprising housing (1), in which hydraulic cavity (4) (HC) is located. Said HC consists of fixed and movable parts, wherein movable part (3) is made in the form of bellows and rigidly connected with fixed part top. On the left side of the fixed part, a conical valve body (6) is installed by means of a threaded connection (TC), in which conical valve (7) is installed, equipped with cylinder protrusion (10) for free passage of fuel into the HC, and with hole in center for free movement along guide rod (8) fixed by means of TC with cover of valve body, in which there are holes (9) for supply of fuel to HC. In lower part of HC there is light guide (23) connected to laser emitter (24) electrically controlled by commands of electronic control unit (26), at that, working frequency of laser emitter is equal to or as close as possible to frequency of absorption of said radiation by fuel.

EFFECT: reduced time of fuel injection into the cylinder, simplified design of the device.
