FUEL INJECTION TIMING DEVICE TESTER Russian patent published in 2005 - IPC

FIELD: mechanical engineering; diesel engines.

SUBSTANCE: invention relates to fuel equipment testing devices for internal combustion engines, particularly to diesel engine injection timing devices. Proposed tester contains angular mark pickup and measuring ring and shutter mated with semicouplings and forming three slots in which like edges of two slots are spaced through reference angle. Circuit of device includes synchronization pickup, scale, of three circuit, cut-in trigger, control trigger, microcontroller and indicator unit. Inputs of scale of three circuit are connected to angular mark pickup and synchronization pickup connected also with control trigger connected in its turn, to cut-in trigger. Outputs of scale of three circuit and control trigger are connected with ports of microcontroller connected with indicator unit realizing calculating functions presented in claim of invention.

EFFECT: decreased errors in measuring angle of turning of semicouplings.
