Why is there a lot of white smoke coming out of the exhaust pipe in winter Why is there a lot of whi

This is the case because the weather is cold in winter, and the water vapor condenses into water droplets.

The breath exhaled by a person contains moisture, which turns into ice when cold in the air, producing white smoke.

I'm a microwave oven manufacturer, can you have some questions:

1.It is normal to have a small amount of white smoke and burnt smell at the beginning of barbecue use, but it should not be the case in the later stage (after a few tens of minutes or 1 or two hours).

2.In the smell of smoke and burnt, there must be no smell of glue, otherwise be careful of short circuit and leakage.

The barbecue of the microwave oven is generally made of quartz tubes and stainless steel, the connection is made of high-temperature wire, and the isolation is made of mica paper and mineral wool, with some oil. At the beginning of use, it is normal for some oil to be evaporated at high temperatures. The top of the furnace is generally controlled by temperature, and the power supply will be cut off if the temperature is over.

So it's generally safe. (It's not clear if black-hearted manufacturers cut corners).

It is true that the quartz tube and the microwave cannot be turned on at the same time, otherwise the power is too large (15A, about 3kw, the socket is generally not acceptable).

It is recommended to open the shell to check, as long as there is no problem with the materials and wiring (focus on checking whether the roof wiring is made of high-temperature wire, woven skin), you can use it with confidence.

Because the weather is cold in winter, the hot air meets the cold air, so there is white air.

The exhaled air contains water vapor, which condenses into small droplets of water when it encounters cold air, like white smoke.

Exhaled water vapor condenses when it encounters cold air.

Condensation of water vapor.

First, the moisture in the fuel is high.

There are two main factors that contribute to this.

First, the buyer's fuel is of very low quality, and the water content in the fuel is high;

The second is that the oil-water separator is faulty and cannot separate the water in the fuel. In both cases, the combustion of fuel with moisture in the cylinder will produce a large amount of unburned hydrocarbons and water vapor, so the exhaust gas is white and appears to emit white smoke.

For this kind of failure, one is to ensure that the purchase of quality assured fuel, and the other is to check the oil-water separator frequently to ensure that there is no fault, and the separated water can be removed in time.

Injector failure:

If the fuel injector in a cylinder of the engine fails, the fuel sprayed by the fuel injector is mixed with air in the form of oil droplets, and the temperature rises by compression, so that the fuel is directly discharged into steam without combustion, and white smoke appears.

The solution to the fault needs to use the method of cylinder breaking one by one to find out the faulty fuel injector and replace it.

A large amount of white smoke from automobile exhaust in winter is caused by excessive moisture in the fuel. Under normal circumstances, the water temperature of the water contained in the oil cylinder of the gas station cannot be higher than 5 mm, and after exceeding this standard, it is seriously mixed with water, which will cause a large amount of white smoke to come out of the exhaust pipe. The following is an introduction to the large amount of white smoke from the exhaust of the relevant winter vehicles:

1. White smoke in the exhaust pipe in winter is a common situation, because the surrounding ambient temperature is relatively low, which is caused by poor combustion atomization, and condensation of exhaust water vapor and small water mist. 2. As long as the engine starts, the phenomenon will disappear automatically with the increase in engine temperature.

In winter, it is normal for the exhaust to emit white smoke, and the water vapor produced after gasoline combustion is normally discharged through the exhaust pipe, and due to the relatively low temperature of the external environment, the water vapor will condense and converge into small water droplets, which will change into water vapor that can be seen by the naked eye.

White smoke from car exhaust in winter is water vapor attached to the inner wall of the exhaust muffler, and white smoke from the exhaust pipe of the car in winter indicates that the exhaust effect of the car is good, so the white smoke from the exhaust pipe is not a fault in most cases. If the emulsified oil mist is discharged from the exhaust pipe, the main reason is that the fuel vaporization is poor, and it is discharged from the exhaust pipe without combustion, forming emulsified fumes. It is common to start the engine in winter, because the temperature is low and the fuel atomization is not good.

Inspect the car

It usually disappears as the engine temperature rises after the engine is started. A large amount of water vapor and white smoke is emitted from the exhaust pipe, and there are water droplets at the outlet of the exhaust pipe. If the exhaust pipe discharges a special hot white oil mist, and the oil mist turns into black smoke when the temperature rises, it means that the cylinder pressure is too low or the individual cylinder is not working, and it should be checked and eliminated.

As part of the coolant enters the cylinder, it will appear as water vapor as the exhaust gas is discharged due to the high temperature. The main pollutants of automobile exhaust include carbon monoxide, nitrogen oxides, hydrocarbons, lead, sulfides, etc. The pollution to the environment is mainly manifested in the greenhouse effect, the destruction of the ozone layer, the production of acid rain, black rain and other phenomena.

This is normal in winter.

That's because when the ambient temperature is relatively low, especially in winter, the exhaust pipe of the car will drip outward, which is actually a very normal phenomenon. Because the gasoline is completely burned after the generation of water and carbon dioxide, water is water vapor at high temperature, water vapor fiber disadvantage hidden gas is colorless and transparent at high temperature, but when the temperature is lower than 100, water vapor will condense into water, if the condensed water droplets are small and suspended in the air, water vapor will appear as white gas, when the ambient temperature is low, white smoke from the exhaust pipe is water vapor;

If condensed water droplets accumulate, it becomes water. The water droplets discharged from the exhaust pipe are the result of condensation of the water vapor generated after the combustion of gasoline in the exhaust pipe and muffler, but when the ambient temperature is high, the water vapor has not yet condensed and has been discharged, and when the ambient temperature is low, the water vapor will condense into water droplets on the exhaust pipe wall, and flow out with the exhaust. This phenomenon is prevalent in cars with good engine work.
