METHOD TO CONTROL FUEL SUPPLY AND DEVICE TO CONTROL FUEL SUPPLY Russian patent published in 2013 - IPC F02M47/02 F02M63/04 F02M45/08 

FIELD: engines and pumps.

SUBSTANCE: device for fuel supply control includes a nozzle with a spring-loaded needle with a mechanical drive, a movement multiplier, a mechanical controller of injection duration, a sprinkler with one level of holes, a high-pressure fuel pump. The device is equipped with an individual fuel pump for every nozzle with a drive from a cam shaft, connected kinematically with a crankshaft, a common hydraulic accumulator of low pressure, a control mechanical valve with a stem with conical or other sealing surface, a quick-acting reversible mechanical drive, a common valve of high pressure control or a high pressure control valve for each nozzle, each quick-acting reversible mechanical drive is equipped with at least one plate for one cylinder with the convex surface of permanent radius at one end with one or several slants on it along its width of the certain maximum length of the convex part of the entire plate with a slat or each of slants, a cam shaft connected kinematically with a crank shaft with at least one programmable profiled cam with at least one microprofile on it with permanent specified low height for realisation of preliminary injection with at least one microprofile.

EFFECT: invention improves dynamics of fuel supply, increases indicator efficiency factor, realises multi-injection and time-controlled injections by means of simple mechanical devices.
