Abstract
A throttle body configured to supply air to an air-intake port of an engine is disclosed. The throttle body typically includes an air-intake passage through which air flows. The air-intake passage at least partially has a non-perfect circle portion with a cross-section of a non-perfect circle shape in a direction substantially perpendicular to a direction of an air flow of air taken in from outside. The non-perfect circle shape typically has long and short axes. At least one of a first throttle valve and a second throttle valve typically is mounted within the non-perfect circle portion of the air-intake passage. The first throttle valve and second throttle valve may include throttle valve members each having a shape conforming to the non-perfect circle shape of the cross-section of the non-perfect circle portion of the air-intake passage. Typically, the first throttle valve and the second throttle valve are each configured to control an amount of the air flow. At least one of the first throttle valve and the second throttle valve is configured to open and close to substantially open and close the air-intake passage.
