FUEL FEED AUTOMATIC CONTROL DEVICE Russian patent published in 2002 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to devices for automatically changing moment of beginning of fuel delivery in internal combustion engines, mainly diesel engines, depending on crankshaft speed and engine load. Invention can be used also in other industries. Said device has servopiston 1 with flyweights 3 fitted on axles 2 and connected with spring-loaded spool 4 arranged in servopiston 1 coupled with drive of fuel pump 8 and placed in rotating housing of fluid coupling 10. Servopiston 1 and housing of fluid coupling 10 form spaces A and Б pressure-filled with oil. Said pressure does not depend on engine speed and indirectly depends on engine load. Spaces A and Б accommodate devices providing working pressure in space Б by freely discharging excess pressure into space formed by housing of fluid coupling 10 and housing of device 17. EFFECT: provision of stable injection advance angle depending on engine speed and load using indirect load factor - engine temperature conditions. 1 dwg
