DEVICE FOR REMOVING COKE FROM NOZZLE SPRAYERS Russian patent published in 1997 - IPC

FIELD: engine engineering. SUBSTANCE: damper is additionally provided in the fuel system of a Diesel. The damper is mounted downstream of the making-up pump and upstream of the reservoir with water solution of additive and fuel, distributor with dropping bottles provided with nozzles. The number of the nozzles is equal to the number of sections of the high-pressure fuel pump. Attachments are arranged on each section of the high-pressure fuel pump and are made up as housings with two inlets and the outlet. The outlets of the dropping bottles are connected with the inlets of housing of the attachments through controllable throttles and check valves. Between the outlet of each housing of the attachment and fuel pipe line of high-pressure is an additional valve with a nozzle. The diameter of the nozzle is 0.15-0.25 of the diameter of the high-pressure fuel pipe line. The volume of air in the damper is not as less as 550 of volumes of cyclic fuel supply produced by the making-up pump. The diameter of the nozzle in the dropping bottle is equal to 0.12-0.22 of the diameter of the plunger of the high- pressure pump. EFFECT: enhanced efficiency. 2 dwg
