How to deal with the freezing of exhaust pipe?

1、? Run a long distance or something, run for dozens of miles and let the exhaust pipe burn.

2、? After winter, once a week, before parking, step on the accelerator a few times and let the water go.

3、? Find a slope, raise the front of the car and let the water flow out.

Many vehicles are difficult to start cold in winter in Northeast China. Found that the exhaust pipe was blocked by ice. The following are the formation principles and solutions of icing under the popularization of small partners:

1, tracheal icing conditions:

2. The temperature is extremely low, below minus 20 degrees.

3. The long-term distance is too short, and I haven't run long-distance or high-speed for several days.

Open at the bottom of the revolution, not willing to give up the throttle, the principle of fuel saving.

As we all know, fuel and gas will produce water vapor. At present, the vehicles leaving the factory are all national four standards, with clean exhaust and large displacement. Because the exhaust pipe is bent, water can't be discharged smoothly. Over time, a large amount of water will accumulate in the exhaust pipe, which will freeze and block the exhaust pipe, resulting in the exhaust gas not being discharged, and the new air not being able to enter the cylinder, which makes it difficult or even impossible to start the engine.

Especially in the case of low temperature in winter in the north, it is easy to condense into water. At the same time, due to the driving habit of short distance and small throttle, the exhaust pipe is more likely to store water and gradually freeze, which is a normal phenomenon.
