Abstract

PURPOSE: To permit reduced-cylinder operation by forming a groove at the edge surface of a control sleeve and reducing the number of cycles of fuel feeding by a plunger by allowing an overflow passage to be opened through the groove, in the distribution type fuel injector of a multicylinder Diesel engine.
CONSTITUTION: When a shaft 36 is turned by use of a lever 57 in idle revolution of an engine, the control sleeve 24 which is inserted outwardly and slidably onto the plunger 52 for compressing a certain amount of fuel is turned around the plunger 52, and an overflow passage 21 communicates to a groove 41 during the feeding cycle of the plunger 52, and feeding of fuel to a specific cylinder is obstructed, and reduced-cylinder operation is permitted. Consequently, the overflow passage 21 coincides with the groove 41 when the plunger 52 starts feeding cycle from the retreat position, and this state is maintained to suppress the feeding of fuel to a specific cylinder during the feeding cycle.
