A structure of a throttle body directly connected with an SCV(Swirl Control Valve) of a diesel engine is provided to prepare against adherence of a throttle shaft due to stacking of carbon by controlling a flap of a throttle body with a motor having higher torque than a conventional negative pressure actuator. A structure of a throttle body includes a suction manifold(40), a throttle body(50), and an SCV(60). The suction manifold is installed at an engine to supply air to each cylinder of the engine. The throttle body is installed at one end part of the suction manifold, changes an air quantity flowing in the engine, and controls speed of the engine. The SCV is installed by a link unit at one side of the throttle body and generates a swirl of sucked air. The link unit includes a first link member(81), a link driving unit, and a second link member(82). The first link member is installed at one side of the throttle body. The link driving unit is installed at the SCV and one side of the link driving unit is connected to the other end of the first link member. The second link member is installed at the other side of the link driving unit and is connected to the suction manifold. |
