FUEL SUPPLY DEVICE FOR ENGINE

摘要

To make it possible to perform pressure-feed of a fuel from a supply pump into an accumulation chamber even if pressure control means disposed in a fuel pressure-feed passage are not operated. In a fuel supply device for an engine, pressure control means (20, 40) for controlling a fuel pressure in the accumulation chamber (2) are disposed in the fuel pressure-feed passage for performing pressure-feed of a fuel from a feed pump (16) into the accumulation chamber (2) through the supply pump (3) having plungers (5, 5). At least one of the fuel pressure-feed passages for performing pressure-feed of the fuel from the feed pump (16) into the accumulation chamber (2) through the plungers (5, 5) is not provided with the pressure control means (20, 40), and other fuel pressure-feed passages are provided with the pressure control means (20, 40).
