The weather is gradually getting colder, and the temperature at night is also gradually dropping. Winter is coming soon. The cold weather in winter is a huge test for cars and will cause some car faults to the majority of car owners. Let me tell you about these faults and solutions in winter.

Difficulty starting the car when it is cold in winter

When you get up in the morning, insert the key, and suddenly find that your car cannot start or start. I believe many car owners have encountered this situation in winter. This is the phenomenon of difficulty starting when the car is cold in winter.

The main reasons for this phenomenon are the following:

First of all, the battery power is insufficient. Since the power consumption of the car battery in winter is significantly higher than that in other seasons, and the battery capacity will also decrease in low temperature environments, the battery will be insufficient. At this time, you need to go to a specialty store to charge the battery in time or replace it with a new one.

Secondly, the flow of engine oil is blocked. This situation is more obvious in the north where the temperature drops. At low temperatures, the viscosity of the engine oil will also increase, and the fluidity will decrease, which will increase the engine running resistance, making it difficult to start the engine cold. This requires the car to be placed in a warm environment, and it can start normally after a period of time. However, if you want to completely solve the problem, you need to perform winter maintenance in time and replace the engine oil suitable for winter use.

In addition, frozen exhaust pipes or carbon deposits on the valves will also make it difficult to start the engine. Frozen exhaust pipes are mainly due to the infrequent use of the car in winter. The water vapor generated after the engine is burned freezes in a certain part of the exhaust pipe, and short-distance driving cannot melt the ice. Over time, it will affect the starting and exhaust of the car. In fact, as long as the car owner drives on a high speed and keeps the engine running at high speed, the strong exhaust force will quickly drain away the water in the exhaust pipe. Valve carbon deposits are caused by incomplete combustion of gasoline in the combustion chamber. These colloidal substances adhere to the throttle valve and block the throttle valve. Therefore, it is recommended that car owners clean the electronic throttle valve regularly to avoid the adverse effects of carbon deposits on the car.

Idle jitter during cold start in winter

When the engine is started at low temperature, jitter will occur. The root cause of this situation is insufficient combustion in the cylinder. The reasons are as follows: The mixing ratio is inappropriate. The main reason is that the degree of atomization of gasoline is not enough, which causes problems with gasoline combustion in the cylinder. It is recommended that after the car is powered on, wait for two or three seconds before igniting it.

Carbon deposits on valves and intake ducts. If carbon deposits occur in the valves and intake passages of the engine, the carbon deposits can absorb an appropriate amount of fuel, resulting in insufficient combustion and engine vibration. It is recommended that riders perform regular maintenance and clean up the carbon deposits. The working conditions of each cylinder are different. The reason why the working conditions of each cylinder are different is also that there is excessive carbon deposits or aging on the spark plugs. It is recommended to check and maintain regularly and replace the spark plugs in time.

Accelerating and breaking into cars at low temperatures

Accelerating and breaking into cars at low temperatures is also one of the common car faults in winter. The main reason is due to insufficient heating of the car, so the correct method of heating the car is particularly important. Generally, a car should be on the road 30 seconds to one minute after the car is started in winter. However, do not drive at a high speed at this time. You should keep the vehicle speed at a low speed, and the engine speed should not exceed 3000~3500 rpm. Generally maintain 2000 rpm. If you step on the accelerator hard at this time and increase the speed too quickly, it will cause greater wear and tear on the parts in the engine and gearbox. The correct method is to wait for the engine temperature to rise to the normal range, and then drive according to personal driving habits.

Under normal circumstances, the following times can be used as a reference for low-temperature car heating in winter: 90 seconds above 0 degrees Celsius, 120 seconds for preheating at minus 5-0 degrees Celsius, 150 seconds for preheating at minus 5-10 degrees Celsius, and 200 seconds for preheating below minus 10 degrees Celsius.

The above are the faults and solutions that I have summarized for you. I hope that after reading this, your car will not have this problem in winter and the damage to your car will be reduced. If there are friends who are interested in this, you may wish to learn about it and pay attention.
