by the electronic throttle wire harness (wire) cable or rod in place, mounted on a miniature motor there throttle, the electric motor driving the throttle opening degree. The so-called “wire driving”, with a wire to replace the original mechanical transmission.
1. The electronic throttle noun
by the electronic throttle wire harness (wire) cable or rod in place, mounted on a miniature motor there throttle, to drive the motor throttle opening. The so-called “wire driving”, with a wire to replace the original mechanical transmission.
2. The principle of the electronic throttle valve
Electronic throttle opening of the throttle valve is controlled by a cable or harness, and automatic control function.
When the driver depresses the accelerator required throttle pedal position sensor will be sensing a signal is transmitted to the ECU via conventional electronic throttle and the throttle cable, ECU through the analysis, determination, and issues an instruction to the drive motor, by drive motor control of the opening degree of the throttle valve to adjust the flow rate of the combustible mixture, when the large load, large throttle openings, into the combustible mixture within the cylinder multiple, if using the throttle cable can only rely on the depth of the foot pedal to the throttle throttle valve opening control, the opening angle of the throttle valve is difficult to achieve the theoretical air-fuel ratio is adjusted to a state, and the electronic throttle ECU through various data collected by the sensor analysis, comparison, and command the throttle actuator operation mechanism, the throttle valve adjusted to the optimum position to achieve different loads and conditions can be close to 14.7: 1 stoichiometric air-fuel state, to fully burn the fuel.
Electronic accelerator car accelerator pedal is “false throttle”, but a receiver, after receiving the driver stepped on the accelerator operation, the operation will be the strength and amplitude data to the control unit for analysis then summed driver’s intention throttle, then by the control unit in accordance with the calculated actual degree a throttle opening control command section and valve motor operation.
