Why does gasoline not burn enough in winter?

Landlord, we say gasoline is not fully burned, and a large part of this situation is due to weather factors. Because gasoline is a mixture, mostly carbon.

8. A mixture of petroleum hydrocarbons (alkanes, olefins, benzene, etc.), the properties of gasoline determine that it cannot be completely burned in an instant. Especially in winter, when the temperature is low, it is more difficult to burn completely.

In normal engine operation, gasoline is injected into the combustion chamber in the form of a mist, so it is usually difficult to maintain a liquid state at high temperatures and pressures. This is where the problem of oil mixed with gasoline (increased oil) comes in, and there are generally two reasons why gasoline can remain liquid in the combustion chamber

During the cold start, the amount of fuel injected is too large (shabu-shabu), and the gasoline flows into the oil pan along the gap between the cylinder wall and the piston (ring) that is not sealed by the oil;

2.Reasons for the long-term aging of cylinder walls and pistons (rings);

However, the mixing of gasoline in engine oil is not new, because as the temperature of the oil rises (about 80 degrees or more), the gasoline mixed in the oil will volatilize, as in some turbotrain engines, the volatile gasoline will flow back to the intake manifold through the crankcase forced ventilation device, and thus enter the combustion chamber and be burned.

Therefore, if there is an increase in engine oil, as long as the car is heated up before driving, the oil temperature will rise.

In winter, the oil is used more and more, of course, not because there is too much oil, but because the oil is mixed with an unknown liquid – in most cases) gasoline or water. Although it is not a big problem, it is necessary to do a good job of inspection in winter.

The increase in oil is usually caused by incomplete combustion and internal coolant leakage. The former dilutes the oil and the latter emulsifies the oil, both of which affect normal lubrication and cause engine wear and damage. Therefore, it needs to be repaired in time and replaced with new oil before continuing to operate.

Insufficient fuel combustion may lead to an increase in carbon deposits, so that the car will be heavier to drive, so it is necessary to ensure that the fuel is fully combusted, so as to ensure the health of the vehicle.

The consequence is that there will be waste, and insufficient fuel will consume a lot of oil, which will increase costs.

It will cause the exhaust gas to be black, and it will increase fuel consumption, pollute the environment, and affect the power.

The reasons for insufficient gasoline combustion are: 1. The engine rotates low for a long time, causing carbon deposits in the engine position, and even the engine position is stuck with sticky and incomplete combustion; 2. There is an exhaust gas circulation system in the car, which is opened when driving, and a part of the exhaust gas is introduced into the cylinder, which affects the lack of oxygen in the combustion chamber and causes insufficient combustion; 3. The engine has a lack of cylinders, and an engine has 6 combustion cylinders, one of which does not work or works poorly, causing insufficient combustion; 4. If you usually use the oil that you don't want to destroy and Liang's suspicion, it will also affect the insufficient combustion. The manifestation of insufficient gasoline combustion is black smoke from the exhaust pipe, the exhaust gas has a very large gasoline smell and the fuel consumption increases, and the engine is weak.

Insufficient gasoline combustion will lead to black smoke from the exhaust pipe, and the exhaust gas will have a strong gasoline smell and increase fuel consumption, and the engine will be weak.

Insufficient gasoline combustion solution:

1. The engine rotates low for a long time, causing carbon deposits in a little place, and even a point in the position is stuck with sticky and incomplete combustion, which further causes insufficient combustion and affects the increase in fuel consumption.

2. Some cars have an exhaust gas circulation system, which is closed in the normal state of driving and driving, because there is a fault in the driving state, and a part of the exhaust gas is introduced into the cylinder to affect the lack of oxygen in the combustion chamber, causing insufficient combustion, the solution: go to the repair shop to repair the exhaust gas circulation system.

3. The engine has a "lack of cylinder", simply put: an engine has 6 combustion cylinders, one of which does not work or works poorly, causing insufficient combustion, and the car will also have a clear trembling vibration when driving up and running, the solution: go to the car repair shop and repair the combustion cylinder with faulty chains.

4. If you usually use bad oil, it will also affect the insufficient combustion, solution: use a better quality oil, do not need to mix the two gasoline in order to save money.

Insufficient combustion of gasoline will increase carbon deposits in the engine, and the car will be weak if you press the accelerator hard.

Gasoline burns in an engine and requires air to mix with it. If the air cannot be mixed well with the gasoline, then the gasoline cannot be fully burned in the engine.

If the ECU cannot accurately adjust the air-fuel ratio, it will also affect the insufficient combustion of gasoline in the engine.

The oxygen sensor is responsible for checking the oxygen content in the exhaust gas. There are two oxygen sensors, one behind the exhaust manifold and the other behind the three-way catalytic converter. The oxygen sensor feeds a signal back to the ECU, which then adjusts the air/fuel ratio based on this signal.

If the ECU does not accurately adjust the air-fuel ratio, the gasoline will not burn sufficiently.

The oxygen sensor needs to be replaced. If it is not replaced after long-term use, the oxygen sensor will fail.

When using the car at ordinary times, you must not add low-quality gasoline, which may not burn enough. If the engine carbon deposit is serious, then the car rider is encouraged to remove the engine carbon deposit. A very good way to remove carbon deposits is the walnut sand removal method.

Many auto repair shops use the dropper bottle method to remove carbon deposits. This method simply does not completely remove carbon deposits. I appeal to cyclists not to use this method.

When you usually use the car, you can add some additives to the fuel tank of the car, which can shorten the carbon deposit in the engine.

Finally, () Bian Xiao is honored to answer for you, about the performance of insufficient gasoline combustion? I have some opinions on this issue, and I hope you can find it helpful after reading it! If necessary, Bian Xiao is waiting for your visit in this trillion digging annihilation.

Insufficient gasoline combustion will lead to black smoke from the exhaust pipe, and the exhaust gas has a great gasoline smell and increased fuel consumption, and the engine is weak.

Solution to insufficient combustion of wax oil:

1. The engine rotates low for a long time, causing carbon deposits in a little place, and even a point in the position is stuck with sticky and incomplete combustion, which further causes insufficient combustion and affects the increase in fuel consumption.

2. Some cars have an exhaust gas circulation system, which is closed under normal driving conditions, because there is a fault in the driving, and a part of the exhaust gas is introduced into the cylinder to affect the lack of oxygen in the combustion chamber, causing insufficient combustion, the solution: go to the repair shop to repair the exhaust gas circulation system.

3. The engine has a "lack of cylinder", simply put: an engine has 6 sliding combustion cylinders, one of which does not work or works poorly, causing insufficient combustion, and the car driving will also have a clear trembling vibration, solution: go to the car repair shop and repair the faulty combustion cylinder.

4. If you usually use the oil with poor ear bend, it will also affect the insufficient combustion, the solution: use a better quality oil, and do not mix the two gasolines in order to save money.

Insufficient gasoline combustion is manifested as black smoke from the exhaust pipe, and the exhaust gas has a great gasoline smell and increased fuel consumption, and the engine is weak. The reasons for the insufficient burning of gasoline abrasive pins: 1. The engine rotates low for a long time, causing carbon deposits in the engine position, and even the engine position is stuck with sticky and incomplete combustion; 2. There is an exhaust gas circulation system in the car, which is opened when driving, and a part of the exhaust gas is introduced into the cylinder, which affects the lack of oxygen in the combustion chamber and causes insufficient combustion; 3. The engine has a lack of cylinders, an engine has 6 combustion cylinders, and one cylinder in its section is not working or working poorly, causing insufficient combustion; 4. If you usually use bad oil, it will also affect the insufficient combustion.

Insufficient combustion of gasoline will increase the carbon deposits in the engine, and the car will not be strong when you step on the accelerator.

Gasoline is burned in an engine and requires a body of air to mix with it. If the air gas cannot be mixed well with the gasoline, then the gasoline cannot be fully burned in the engine.

If the ECU does not accurately adjust the air-fuel sensitivity ratio, it will also lead to insufficient gasoline combustion in the engine.

Oxygen sensors are responsible for detecting the oxygen content in the exhaust gases. There are generally two oxygen sensors, one behind the exhaust manifold and the other behind the three-way catalytic converter. The oxygen sensor responder feeds a signal back to the ECU, which then adjusts the air-fuel ratio based on that signal.

If the ECU does not precisely adjust the air-to-fuel ratio, the gasoline will not burn sufficiently.

The oxygen sensor needs to be replaced. If it is not replaced after long-term use, the oxygen ramp lift sensor will fail.

Do not add low-quality gasoline to your car, this gasoline cannot be fully burned. If the engine has significant carbon deposits, riders are advised to clean up the engine carbon deposits. The best way to remove carbon deposits is walnut sanding.

Many garages use hanging bottles to remove carbon deposits. This method does not completely remove the carbon deposits at all. Riders are advised not to use this method.

When you usually use the car, you can add some additives to the fuel tank, which can reduce the carbon deposits in the engine.

Millions of car purchase subsidies.

Summary. 1. Insufficient oxygen supply. The total amount of oxygen may be sufficient, but for the flame, local hypoxia is certainly present.

2. The large particles of the oil droplets sprayed out cause the surface area to be small, and the combustion time is not long enough.

3. The cetane number is low, and the combustion rate of diesel itself is slow.

4. The large gap between the cylinders causes air leakage, that is, the loss of compression ratio.

5. The injection advance angle of the diesel engine is not suitable.

6. The change of load and speed causes the pressure-ignition incompatibility.

7. The high temperature of the cylinder wall causes the coking and carbonization after the oil droplets.

Why does diesel fuel burn inadequately.

Hello, your question has been received <>

Answer: Xiao Yue'er is sorting out the answers to the questions, please wait a while<><

Dear, wait a minute. I'll send you the reason.

Dear, I've been waiting for a long time, as far as I know, for the following reasons:

1. Insufficient oxygen supply. The total amount of oxygen may be sufficient, but for the flame, local hypoxia is certainly present. 2. The surface area is small due to the large particles of the oil droplets sprayed, and the combustion time is not sufficiently long.

3. The cetane number is low, and the combustion rate of diesel itself is slow. 4. The large gap between the cylinders causes air leakage, that is, the loss of compression ratio. 5. The injection advance angle of the diesel engine is not suitable.

6. The change of load and speed causes pressure-ignition not to trap the training and production. 7. The high temperature of the cylinder wall causes the oil droplets to be coking and carbonizing after Fu Wang Jingwei.

Secondly, there is also the unstable quality of diesel.
