Low temperature in winter can easily lead to freezing of automobile exhaust pipes. When the car is driving at a low speed, the exhaust pressure will decrease. At this time, the water burned by the in-cylinder direct injection engine will remain in the exhaust pipe and will not be evaporated. Once it is cold, it will freeze, and there will be a bubbling sound at the tail of the exhaust pipe of the car.
