It can be used for the equipment of electrical-controlled fuel injection in gasoline engine.
One wire to connect throttle body with the accelerator pedal, through pressing the accelerator to adjust the size of the throttle valve and thus to control the air inflow for the engine to have the power and speed. Meantime, the throttle position sensor will send the position feed back signal to ECU to help the engine adjusting the air flow in the bypass. The big slide that opens and closes your throttle has a bevel angle cut in one side of the big round (can be flat, too) slide, toward the air cleaner. This angle comes in several sizes and helps control the fuel mixture from idle to about 35% open throttle. We have 7 different items for different adaptive engine (e. G. 491q, 4G64, 488Q, 465Q, 364Q, 495Q, 462)

When the valve core on moves when the valve lever promotion function turns on a valve core set of throttle,The fluid first reduces expenses by the cone-shape the vice- valve petal less advanced to reduce expenses to enter the valve seat cavity,Again operates the throttle through the valve core wrap which the hole spot andthe valve core nose column surface forms to discharge. In throttle process,The major part pressure adds in the cone-shape reduces expenses on the vice- valve petal,The small partial pressure adds on a valve core set of throttle,The high speed fluid is much more serious than to the spray nozzle attrition the throttle,But wears the cone-shape reduces expenses the vice- valve petal to be advantageous for the replacement.
The valve core and the valve seat hard alloy sealed vice- and softly seals vice-between has formed the double nature seal, had guaranteed the valve bore washes
out and the zero divulges the request.
The balance design of open and close structure On the valve core opens has the balancing hole, causes, under the cavity medium to be at the state of equilibrium, enhanced the stability and the reduction which the valve opens opens the resistance.
