FUEL SUPPLY STRUCTURE IN ENGINE

摘要

An intake manifold (85) having integrally a surge tank (82), a plurality of intake pipes (83a to 83d) and a mount flange (84) is provided at the mount flange (84) with a plurality of fuel injection valves (94). A subtank (89) provided therein with a high pressure fuel tank (91) and provided outside thereof with a high pressure filter (93) for temporarily storing a fuel to be supplied to the fuel injection valves (94) is secured to intake pipes (83c, 83d) by means of two bolts (106) and secured to a cylinder block (6) by means of two bolts (107). The high pressure tank (91), high pressure filter (93) and the subtank (89) are beforehand assembled to the intake manifold (85) to make a subassembly, and the subassembly is collectively assembled to an engine to thereby reduce assembling manhours.
