Description

Twin throttle valve Mechanism

The present invention relates to a throttle valve mechanism that controls the amount of mixer that is sucked into the cylinder during the intake stroke of an automobile engine, which reduces frictional resistance, forms vortices and turbulences, accelerates the flow of air, and mixes with the fuel. The present invention relates to a twin throttle valve mechanism that improves combustion efficiency and improves combustion efficiency.

In general, an intake device for a vehicle passes through an air purifier that removes foreign substances in the inflowing air and removes intake noise generated in an intake pipe, and the air purifier described above. In the throttle valve mechanism for adjusting the amount of air, a surge tank for temporarily storing the flow of intake air passing through the throttle valve mechanism and supplying evenly to each combustion chamber in the engine, and the surge tank It consists of an intake manifold that dispenses the mixer.

The throttle valve mechanism is supported by a throttle body in which a passage through which air is introduced, a rotation shaft rotatably installed in the throttle body, a throttle valve for opening and closing the passage of the throttle body, and the rotation shaft. A throttle lever coupled to one end of the claw and a return spring for returning the throttle lever to its original position.

In the throttle valve mechanism, the throttle lever is connected to the accelerator pedal and the throttle wire, and the throttle lever is sucked into the engine by opening and closing the throttle valve at a predetermined angle while rotating the throttle lever at a predetermined angle according to the operation of the accelerator pedal. Adjust the air volume.

A throttle position sensor is installed on the opposite side of the throttle lever according to the rotating shaft to sense the opening / closing amount of the throttle valve.

The throttle body is typically formed in a cylindrical shape with a constant internal diameter along the longitudinal direction, and a circular throttle valve is rotatably installed in the passage.

Since the throttle valve mechanism for automobiles formed as described above has one throttle valve, since the contact area with air is large, frictional resistance such as vortex and turbulence is severe. It happens.

Therefore, if the frictional resistance is increased, the piston takes more force to suck into the combustion chamber, so the power loss is increased and eventually the engine power loss occurs.

An object of the present invention is to solve the above problems, by dividing the contact area when the intake air passes through the throttle valve to reduce the frictional resistance, such as turbulence and vortex, and the longitudinal direction on the inner surface of the passage Accordingly, it is to provide a twin throttle valve mechanism that divides the spiral protrusion at a predetermined angle to form one or more rows to accelerate the flow of air to improve the mixing with the fuel, thereby increasing the combustion efficiency and reducing the power required.
