What if the throttle line freezes in winter?

After the Pacific car network melts, remove the cable, inject engine oil from one end of the cable, pull it back and forth, and repeat it, and then the icing problem can be solved.

Next to it is an acceleration pump pipeline, which allows the carburetor to spray an oil to the throat when the throttle turns sharply to improve the acceleration when the throttle turns sharply. This accelerator pump only works when the throttle is sharp, but it doesn't work when driving normally or the throttle is slow. When parking a car equipped with this carburetor, be careful not to twist the throttle, otherwise it will inject gasoline into the cylinder, causing flooding and wasting gasoline.

The traditional cable accelerator is a steel wire with one end connected to the accelerator pedal and the other end connected to the throttle, and its transmission ratio is 1: 1. That is to say, the throttle opening is the angle we step on with our feet, but in many cases, the throttle should not be opened at such a large angle, so the throttle opening at this time is not necessarily the most scientific. Although this method is direct, its control accuracy is poor. The electronic throttle controls the opening of the throttle through cables or wire harnesses. On the surface, the traditional throttle cable is replaced by cable, but in essence it is not only a simple change of connection mode, but an automatic control function for the power output of the whole vehicle.

Electronic throttle control system is mainly composed of accelerator pedal, pedal displacement sensor, ECU (electronic control unit), data bus, servo motor and throttle actuator. The displacement sensor is installed in the accelerator pedal to monitor the position of the accelerator pedal at any time. (Photo/Text/Photo: Pacific Auto Network Yang Yulin)
