Throttle Throttle is a general name for, the opening angle is changed through different inlet flow, the air flow meter to the inlet air flow sensing sensing signal, which transmitted to the vehicle computer-controlled engine speed an important component. General form of the vehicle more than a single throttle, installed in the intake manifold body mouth, using the throttle valve with axial opening of the sheet to change the inlet air flow. Throttle opening is divided into mechanical and electronic motor open type, mechanical opening ceremony by a cable connected with the throttle pedal flake control valve open, the advantage of simple direct response to the disadvantage of low precision movements, high fuel consumption! Electronic accelerator pedal opening ceremony by the stepper motor to control throttle cable pair and the special sheet of the valve control unit consisting of electric motor control, depress the accelerator pedal when the stepper motor control section will be the signal transmitted valve sheet valve electric motor, trip computer according to the actual engine operating conditions the valve opening angle control sheet, so that accurate and reasonable control, so that the fuel consumption to be effectively controlled, the disadvantage is not a direct reaction, structure is more complex.

In order to improve the actual intake air flow, there have been modified to increase the original throttle method. As follows:

1, the expansion of throttle diameter;

2, the processing of the door inner diameter and solar terms is exactly equal to the sheet valve, in order to ensure oil return to prevent microleakage sluggish, unstable idle to happen, there is the rotation axis of the valve sheet thinning treatment to prevent interference into the air shaft stability.

In addition to the note and the original sheet to be used as spring material production, and the body wall to prevent the valve between the Penghu expansion coefficients for different materials produced microleakage problem of the poor, while processing the film to reserve shaped valve rotation required about 3 degrees slope.

In addition to the original throttle for further processing, as well as finished product high performance large diameter throttle can choose, through a special type of throttle design and processing, and precision more secure. Dress often make large-diameter throttle flow signal abnormalities, computer-controlled traffic signal shift, etc., and therefore the need for traffic management procedures to modify the computer or re-poured.
