Abstract
In addition to a conventional first communication passageway communicating the suction space of a distributor-type fuel injection pump with a hydraulic oil chamber defined at one end of the timer piston via a servo valve acting to prevent vibration of the roller holder, a second communication passageway is provided for communicating the suction space with the hydraulic oil chamber while the timer piston is displaced at least through a stroke corresponding to a predetermined starting advance in the injection timing. Selector means closes the first communication passageway and simultaneously opens the second communication passageway when a temperature of the engine is below a predetermined value, while it opens the first communication passageway and simultaneously closes the second communication passageway when the temperature of the engine is above the predetermined value, to thereby achieve positive starting of the engine in a cold condition.
