Abstract
A torque increase resonator includes: a plurality of resonance pipes that extend outward from an intake passage supplying air to an internal combustion engine; one resonance chamber that is formed so that end portions of extending portions of the plurality of resonance pipes are positioned in an internal space of the resonance chamber; and a valve that opens and closes an opening of the extending portion of at least one resonance pipe of the plurality of resonance pipes, wherein the intake passage and the resonance chamber communicate with each other through the plurality of resonance pipes, and the plurality of resonance pipes are close to each other, and are disposed on a downstream side of a throttle in a flow direction of air in the intake passage.

A torque increase resonator comprising:
- a plurality of resonance pipes that extend outward from an intake passage supplying air to an internal combustion engine;
- one resonance chamber that is formed so that end portions of extending portions of the plurality of resonance pipes are positioned in an internal space of the resonance chamber;
- and
- a valve that opens and closes an opening of the extending portion of at least one resonance pipe of the plurality of resonance pipes,
- wherein the intake passage and the resonance chamber communicate through the plurality of resonance pipes,
- the plurality of resonance pipes are close to each other, and are disposed on a downstream side of a throttle in a flow direction of air in the intake passage, the plurality of resonance pipes are disposed in a surge tank of an intake manifold, the intake manifold comprising a plurality of ports,
- the plurality of resonance pipes comprising a first resonance pipe possessing a center axis and a second resonance pipe possessing a center axis, and
- the plurality of ports of the intake manifold are disposed so that a distance from one of the plurality of ports to the center axis of the first resonance pipe equals a distance from the one port to the center axis of the second resonance pipe.
A torque increase resonator comprising:
- a plurality of resonance pipes that extend outward from an intake passage positioned to supply air to an internal combustion engine, the plurality of resonance pipes comprising extending portions;
