The traditional cable-pull accelerator is connected to the accelerator pedal at one end and the accelerator at the other end through a wire. Its gear ratio is 1:1, which means that the throttle opening is the same as how much we step on it. But in many cases, the throttle should not be opened at such a large angle, so the opening of the throttle at this time is not necessarily the most scientific. Although this method is straightforward, the control accuracy is poor.The electronic throttle valve controls the throttle opening degree through a cable or wiring harness. On the surface, it replaces the traditional throttle cable with a cable, but in essence it is not just a simple change of the connection method, but an automatic control function that can realize the power output of the whole vehicle.
When the driver needs to accelerate, step on the accelerator and pedal position, the sensor will transmit the sensed signal to the ECU through the cable. After analysis and judgment, the sensor will send a command to the drive motor, and the drive motor controls the throttle opening to adjust the flow of the combustible mixture. When the load is heavy, the opening of the throttle valve is large, and the combustible mixture entering the cylinder will enter the air-fuel mixture more. With a cable-pull throttle, the opening can only be controlled by the depth of the pedal. It is difficult to adjust the throttle opening to achieve the stoichiometric air-fuel ratio. The electronic throttle valve can analyze and compare various data collected by the sensor through the ECU, and issue commands to make the throttle valve actuator act, so as to adjust the throttle valve to the best position, so that it can reach a ratio of nearly 14.7: 1 under different loads and working conditions. Theoretical air-fuel ratio to fully burn the fuel.
Here's how to adjust a car's throttle line:
Simply tighten the adjusted position in the opposite direction of the thread loosening. But don't be too tight, the throttle is very sensitive, the throttle cable is pulled too tight, there is no free travel. During exercise, the throttle opening will increase, the computer signal voltage will be slightly higher, and the fuel injection volume will increase, resulting in the engine idling too high and waste oil being used.
Pay attention to maintenance
When adjusting auto parts, also pay attention to the maintenance of auto parts. Timely maintenance can prolong the life of accessories. If the maintenance is not in place, once the accessories are damaged on the road, it is still a troublesome thing.
