Abstract
The invention discloses a proportional electromagnetic electronic throttle controlling method. An electronic throttle controller is used for controlling the movement of the throttle drawbar on the jet pump by proportional electromagnet, i.e. the signal of a throttle pedal sensor is input into the electronic throttle controller to be processed and the processed signal is output to the proportional electromagnet to drive the axial movement of the proportional electromagnet, so the throttle drawbar of the jet pump is powered by the proportional electromagnet to control the amount of the fuel in the jet pump. In the proportional electromagnet for controlling the throttle drawbar a spring or a torsional spring is set, so as to make the running more reliable.
