ASSEMBLY FOR ESTIMATING LOW-TEMPERATURE PUMPING OF FUEL FOR DIESEL ENGINES Russian patent published in 2005 - IPC

FIELD: engine manufacturing.

SUBSTANCE: assembly can be used in modern auto-tractor and armor-tank equipment. Assembly has fuel container with filled-in neck and discharge branches, both disposed in thermal chamber. Stop valve is mounted onto first branch. Neck and branches are connected in sequence along flow of strainer. Assembly also has fuel booster pump, receiving container and unit for controlling sequence of operation. Corresponding inputs of control unit are connected with fuel temperature detectors inside container and in front of strainer, with detector of pressure drop onto strainer and fuel discharge detector through fine filter. Corresponding outputs are connected with stop valve onto first discharge branch and with actuating mechanism of booster pump. Assembly is provided with centrifugal fuel pump which has sucking-inline connected with second discharge branch of container, with manual booster pump mounted in front of fine filter, three-wave cock through which head line of centrifugal pump is connected either with sucking-in line of manual booster pump or through the first discharge branch - with container, and additional stop cocks. One cock is disposed between fine filter and fuel discharge detector, and the other one - onto additional fuel duct which connects basic fuel duct with neck of fuel container in front of fine filter. Control inputs of centrifugal fuel pump, three-way cock and additional stop cocks are connected with corresponding outputs of unit for controlling sequence of operations.

EFFECT: improved precision of results; improved truth of results.
