HIGH PRESSURE FUEL PUMP TESTING DEVICE Russian patent published in 2012 - IPC F02M65/00 G01M15/04 

FIELD: engines and pumps.

SUBSTANCE: HP fuel pump testing device includes frame with HP fuel pump installation plate mounted on it, drive, injector, fuel feed system and measuring devices of phase parameters, capacity and non-uniformity of fuel feed with pump sections, which are combined in one measuring channel provided with possibility of alternate connection to each pump section and related to information control and processing system. Pipelines for fuel drain from the sections not involved in the test are connected to fuel tank of fuel feed system through the header at the outlet of which a bypass valve adjusted to the opening pressure equal to maximum pressure created with fuel feed pump is installed.

EFFECT: invention allows performing the tests and adjustment of HP fuel pumps of different types, including those meeting the requirements of EURO-3 standard, the parameters of which, and namely pressure of actuation of delivery valves of the sections, differ from parameters of HP fuel pumps of previous generations, as well as HP fuel pumps the delivery valves of which have misalignments or failures.
