DIESEL TRACTOR POWER SUPPLY SYSTEM WITH MANUAL CONTROL OF MIXED FUEL SUPPLY Russian patent published in 2019 - IPC F02M43/00 F02D19/06 F02M37/00 

FIELD: machine building.

SUBSTANCE: invention relates to propulsion engineering. Feeding system of tractor diesel engine with manual control of mixed fuel supply contains vegetable oil and mineral fuel tanks (1 and 2), mixer (15) in inlet channels (17 and 18) of which there are throttle valves (19 and 20) with control levers (21 and 22) controlled by control levers (23 and 24). Control levers (23 and 24) are kinematically by means of longitudinal tie rod (26) and compensating link (27) are connected to rotary two-arm lever (28), having the possibility, under action of externally applied force, to move in slots of rigidly fixed sector (30) with indicator ( 31) ratio of vegetable oil and mineral fuel in mixed fuel. For rotation of throttle valve (20) regulating supply of vegetable oil, at a certain angle during its opening and corresponding synchronous rotation of throttle valve (19), which controls supply of mineral fuel, exactly at same angle when it is closed ratio of lengths of control levers (23 and 24) by turning throttle shutters (19 and 20), lengthwise rod (26) and compensating link (27) should be equal to 1:10:2 respectively. Depending on the value of external resistance to movement of tractor operator manually, by rotating rotary double-arm lever (28) along sector (30), establishes required ratio of vegetal and mineral components of mixed fuel or if necessary transfers diesel to mineral fuel.

EFFECT: providing required angles of rotation of throttle valves at their synchronous control and, consequently, more accurate ratio of mineral fuel and vegetable oil contained in mixed fuel.
