Fuel supply construction for engines

摘要

An intake manifold 85 having integrally a surge tank 82, a plurality of intake pipes 83a to 83d and a mounting flange 84 is provided at the mounting flange 84 with a plurality of fuel injection valves 94. A subsidiary tank 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 fuel tank 91, the high pressure filter 93 and the subsidiary tank 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 the number of assembling steps.
