Abstract:
1. A fuel injection apparatus comprising: a plurality of throttle bodies in which an intake passage communicated with an engine is respectively formed, each throttle body including an upstream side injector to inject fuel to the intake passage and a downstream side injector arranged at the downstream side of the throttle body against the upstream side injector to inject fuel to the intake passage; a fuel supply pipe to commonly supply fuel to the upstream side injectors and the downstream side injectors; and a plurality of connecting pipes, a respective connecting pipe connecting the fuel supply pipe to the upstream side injector and the downstream side injector of a respective throttle body; wherein an upstream side branch passage to supply fuel branched from the fuel supply pipe to the upstream side injector is formed inside each of the plurality of connecting pipes, a downstream side branch passage to supply fuel branched from the fuel supply pipe to the downstream side injector is formed inside each of the plurality of connecting pipes, a nip angle of the upstream side injectors is larger than a nip angle of the downstream side branch passages against an intake flow direction of the intake passage, and the nip angle of the downstream side branch passages is larger than a nip angle of the downstream side injectors against the intake flow direction of the intake passage.
