Abstract

PURPOSE: To energize in jet-timing delay direction a fuel-jet timing control timer mechanism by means of a thermo-valve responding to the warm-up operation of a diesel engine for improving starting performance and exhaust characteristic in cold season.
CONSTITUTION: On the starting after the completion of warm-up operation, engine revolutions are small, the rightward pressure of a governor sleeve 74 is prevented by the centrifugal force of a fly-weight 70, and a lever 52 moves a spill sleeve 48 rightward, i.e. in fuel increase direction, by the force of a spring 68. Thereby, the oil to which a high pressure has been given by a feed pump 6 is fed to jet nozzles from a pump chamber 4 through the passages 18 and 20 of a plunger 12 and a delivery valve 30. At this time, fuel jet timing is controlled by a timer mechanism 44 via a cam plate 10. A thermo-valve (not illustrated) is provided to energize the timer mechanism 44 in jet timing delay direction by means of a rod when a thermo- wax furnished therein expands.
