PROBLEM TO BE SOLVED: To prevent fuel from leaking from a seal part by preventing reduction of a sealing property of an O ring made of rubber induced by a deformation of a delivery pipe accompanied with rising of a fuel pressure, reduce a variation of fuel injection amount and carry out a stable fuel injection of an injector by restraining or positively using an influence on pressure inside a delivery pipe of a injection cylinder immediately before an injector. SOLUTION: A central shaft of fastening means 2 such as a bolt with which a delivery pipe 1 is mounted to an engine head 5 and a central shaft of an injector 4 are disposed inside the same plane. An inner passage of the delivery pipe 1 is partitioned to make independent groups so that injecting order of the injector 4 is not sequent, thereby making a plurality of portions in the inner passage of the delivery pipe 1. Alternately, the inner passage in which a plurality of cylinders whose injecting order of the injector is sequent and pressure feed timing of the pump is not included during the injection are grouped are coupled by a throttle of a passage resistor variable valve or the like. |
