Abstract

PURPOSE: To eliminate output loss and enable injection time to be controlled arbitrarily by constituting a fuel injection device from two stages cousisting of an injection plunger for determining injection amount and a forcing feed plunger for determining the injection time.
CONSTITUTION: An injection device is constituted from a forcing feed cylinder 1b, injection cylinder 1a and nozzle 44. A forcing feed plunger 3 rotated and vertically moved by a follower 50 interlocked with an engine is provided in the forcing feed cylinder 1b so that fuel amount to a forcing feed pump chamber 32 is adjusted by a timing lead 30. A injection plunger 2 moved vertically by fuel pressure in the forcing feed chamber 32 is provided in the injection cylinder 1a so that fuel amount supplied from the injection pump chamber 22 to the nozzle 44 is controlled. Also, fuel is supplied from fuel supply pumps 53, 57 to the injection pump chamber 22 through an electromagnetic valve 59 operated in response to load and number of revolution.
