Abstract
In a piping connection structure of a vehicle including: a throttle body connected to a power unit of the vehicle to adjust an intake air amount; a fuel injection device for injecting fuel to an intake passage including the throttle body; first pipings attached to the fuel injection device; and second pipings provided separately from the first pipings, and having end parts connected to the first pipings so as to intersect with the first pipings, a connection part between the first pipings and the second pipings has a long adjustment holes, which extend so as to allow adjustment of relative angles between the first pipings and the second pipings.
Claims4
A piping connection structure of a vehicle comprising:
- a throttle body connected to a power unit of the vehicle to adjust an intake air amount;
- a fuel injection device for injecting fuel to an intake passage including said throttle body;
- first piping attached to said fuel injection device;
- and
- second piping provided separately from said first piping, and having an end part connected to said first piping so as to intersect with said first piping, wherein
- a connection part between said first piping and said second piping has a long adjustment hole, which extends so as to allow adjustment of a relative angle between said first piping and said second piping;
- said connection part includes a flow path forming portion forming a flow path that guides fuel from said second piping to said first piping, a first connection part provided on one side of said flow path forming portion, and a second connection part provided on the other side of said flow path forming portion opposite to said first connection part;
- said adjustment hole includes a first adjustment hole formed in said first connection part, and a second adjustment hole formed in said second connection part,
- when viewed from a vehicle width direction, in said first connection part and said second connection part, said first adjustment hole and said second adjustment hole are shifted closer to a side in which said second piping is connected to said connection part with respect to a center of said first piping,
- said fuel injection device includes a first injector and a second injector;
- said first injector and said second injector are arranged side by side in the vehicle width direction;
- said first piping extends in the vehicle width direction, so as to straddle said first injector and said second injector;
- a supporting member having branch ends and supporting said first piping with said branch end is provided in said throttle body;
- and
- spacers are provided between said branch ends of said supporting member and said first piping.
