Abstract
PURPOSE: To reduce the ON-OFF frequency of a solenoid valve and to improve the controlling accuracy of a fuel injection timing regulator in a device for controlling with tertiary value ON and OFF of an injection timing regulating mechanism by the output of a lead angle characteristic setting circuit of injection timing by setting the lug angle operation speed smaller than the lead angle operation speed.
CONSTITUTION: An injection timing regulating mechanism 30 provided at an injection pump 1 produces an output from the terminal 61 of a tertiary ON-OFF control circuit 60 when the set value θi of the injection timing from the ordinary state becomes, for example, large in case that the deviation becomes higher than Δθi, thereby indicating the leading operation. Then the solenoid valve 40 is switched to its left position, hydraulic oil is supplied to a supply port 21A to move a piston 16 leftwardly. Thus, the phases of the drive and driven shafts 2 and 3 are altered, and the injection timing is regulated to leading angle side. In this case, desired effect can be obtained by providing difference in the openings of throttles 51, 52 interposed in the hydraulic oil conduits between a solenoid valve 40 and a cylinder 17.
