In cold weather, the volatility of the fuel decreases, making the fuel and air mixture often not dense enough, leading to the alignment ratio at the carburetor that directly affects the start. car in cold weather. Even if not
In cold weather or high humidity, the air in the vehicle’s engine condenses into small droplets in the carburetor and fuel pipes. Therefore, the amount of air required to meet the starting process of the vehicle is deficient, causing a difficult situation to explode.
If the car is difficult to start, calmly find out the cause and learn how to fix this phenomenon.
Park your car in the “warmest” places possible
A car battery is a device that stores electricity to power the starter. The low temperature makes the battery’s ability to store electricity reduced, making the energy supplied to the starter not enough to start the engine. Not to mention the cold weather will cause water vapor to condense and can damage the electrical system related to the operation of the starter.
Therefore, park your car in the “warmest” places possible, such as in a garage or covered areas.
Keep the fuel tank full
The low temperature will cause water vapor to condense in the fuel tank into a liquid form and mix with the fuel, seriously affecting the operation of the engine.
And one day, your car won’t start and at the service center, you will have a hard time explaining why the cylinders are full of steam. Keep the fuel always full, the water vapor in the fuel tank is also less and the risk of water mixing in the fuel is also reduced.
Take good care of the car, start “good”
In the long run, to reduce the risk of your car failing to start on low-temperature days, you should take better care of your vehicle with regular maintenance.
Before each cold wave, add or change engine oil and coolant appropriately to ensure that the car does not lack oil and coolant and works well.
First of all, it is recommended to use low viscosity lubricants, specially used for cold conditions. These oils have low viscosity and stabilizer additives that help to eliminate caking at start-up.
In addition, you can add antifreeze additives to the cooling water, helping to lower the freezing point of the water. If your oil filter is nearing its end of life, you should change it as well. The clean filter also helps the oil to circulate better. In winter, you should also check and maintain the battery to ensure that the power source is always strong enough.
Turn off unnecessary devicesTo focus the power on starting the engine, before starting, the driver should turn off unnecessary devices such as air conditioners, radios, lighting systems, etc.
Start up properly
The first operation, anyone can do it, is to turn on the electric lock several times to heat the air. You insert the key into the lock, turn the key to the ON position, wait for the drying indicator light (yellow spring) to turn off and then turn the ignition switch to OFF.
Do the same about 4 to 5 times depending on how cold it is, then start immediately, the engine will be more explosive. When the engine has exploded, don’t step on the gas right away, let the garanti run for a while, the accelerator will slowly increase before starting.
The system boot should also not take too long, should not be more than 20 seconds. If the case does not go up, the driver should call for repair, do not try to start because doing so will damage the mechanical part, the starter and reduce the life of the battery.
When the temperature is low, it not only causes difficulty to start and block the engine in the diesel engine, but also more or less affects gasoline-powered vehicles.
The condition for a gasoline engine to work is to create a mixture of air and gasoline vapor in a certain ratio in the carburetor.
But before that, a certain amount of gasoline must be converted from liquid to gas (vapor). Low temperature means a decrease in the ability of gasoline to evaporate, causing the gasoline in the carburetor to mix with the air improperly, leading to a lack of oxygen, making it difficult to start. If you try to start (start the engine), it will most likely lead to the car running out of gas.
Cold weather not only affects the fuel but also affects the power supply, namely the dead battery due to the chemical change in the solvent in the battery. This problem can be overcome by the driver can use an equally good battery to spare in the trunk or rely on the battery of another car owner nearby.
For gasoline cars, the lubricating oil is often affected more than the fuel, you can choose the right lubricant to ensure cold starting conditions. Regular maintenance and repair of the vehicle is also a more or less effective measure to help the fuel and lubrication systems operate stably, especially when facing bad conditions.
It is very difficult to start a car in the cold season
Car owners need to understand why the car is difficult to start in cold winter weather. From there, you can apply small tips to solve the problem. In addition, car owners should also know how to protect their beloved drivers from difficult to start.
The battery is weak, the fuel is difficult to evaporate, making the car difficult to explode
In winter, when the temperature is low, the fuel is less volatile, so the combustion mixture lacks gasoline (or oil) causing the car to be difficult to start. If your car has a carburetor engine, you can control the lever to pull the throttle, reducing air into the engine so that the concentrated fuel can evaporate.
And if your car uses a gasoline-injected engine, it will be less difficult to explode. Because in addition to the main injector, the system is also equipped with an additional fuel injector when the temperature is low.
Another reason why the car is difficult to start is because the lubricating oil is concentrated because of the cold. Insufficient lubrication ability makes the engine rotation speed not reach the required level, then the electricity in the battery has run out. In this case, car owners should invest in buying a dilute synthetic oil for winter use.
Oil also affects the ability of the car to start
In addition, in the cold season, the chemical composition in the battery also loses its mobility, so it does not provide enough energy to operate the engine. The remedy here is to use a fully charged backup battery, or use a detonator.
Before starting, you should turn off unnecessary devices such as air conditioners, lighting systems, radios… to focus the power on starting the engine. Avoid system booting for too long, no more than 20 seconds.
Note, if the engine still does not run, turn off the engine for a while and then start it again. If the topic doesn’t come up forever If you still try to start it, it will damage the mechanical part, the starter and reduce the life of the battery.
Don’t park your car outside in the cold season
To prevent winter car starting difficult, car owners should know how to take care of their car, engine and other parts. First, choose places that are warm enough to park your car or in the garage, avoid leaving your car outdoors. This helps the car engine not to get too cold, the fuel is more volatile and the battery is not affected.
In addition, you should fill the fuel tank because when the temperature is low, the water vapor condensing in the fuel tank will affect the combustion. In addition, it is necessary to use a special lubricant for winter.
You should also form a habit so that the idle mode when stopping at a red light or stopping time is not too long. This doesn’t save as much fuel as shutting down and restarting, but it avoids a difficult detonation in extreme cold conditions, which takes time.
