6 unexpected reasons why cars spontaneously catch fire
(Baonghean.vn) - Recently, many car fires have occurred, causing many people to worry. To avoid unfortunate incidents, drivers need to equip themselves with skills and experience to recognize the causes and ways to prevent car fires. According to experts, "tuning" the car's interior, the quality of gasoline or leaving a lighter in the car... are also causes of car fires that you do not pay attention to.
1. Mouse bite

Rats are the number one enemy of cars, these animals can destroy anything they like, including things that cannot be eaten. Among them, fuel pipes and electrical wires are two things that rats often target when they get into the hood. Punctured fuel pipes causing fuel leaks can also cause car fires. Cracked electrical wires causing electrical short circuits can also be the cause of car fires.
To prevent this, as soon as you discover traces of rats living in your car, you should have these two parts checked. At the same time, clean the engine compartment to prevent rats from getting used to the smell and returning.
2. Gasoline quality

In case of gasoline that is not guaranteed, it often contains foreign substances that can cause corrosion. Long-term use of poor quality gasoline can lead to punctured fuel tanks, pipes, or increase the possibility of evaporation, causing gasoline vapor to escape uncontrollably. This is also one of the causes of vehicle fires and explosions.
Finding a reputable gas station that guarantees quality is essential. In addition, drivers should also request a thorough check of the above details during each maintenance period. If there are any unusual phenomena, consider changing the gas station and immediately replace or repair these details.
3. "Modify" the car's interior

Many car fires and explosions are found to be caused by installing additional equipment that is not designed by the manufacturer. Arbitrary installation and inappropriate structural changes affect the structure of the electrical system on the car. Normally, the manufacturer only provides enough power for the available equipment on the car. With this power source, many people "expand" many devices on the car, causing electrical short circuits and fires due to overload.
If you want to install additional equipment on your car, you should consult a reputable facility. If necessary, somehow increase the power source for the car to ensure safety before "upgrading".
4. Leave a lighter in the car

Lighters, especially gas lighters, always pose a high risk of fire or explosion. On hot summer days, high temperatures combined with high pressure in the car can easily cause the lighter to explode. In many cases, due to this small error, the interior can burn down, or the entire car can catch fire.
In addition, flammable items such as perfume, soda cans, and spare battery chargers should not be left in the car because closed, unventilated places pose a high risk of fire or explosion.
5.Mini fire extinguisher

Many drivers often do not pay much attention to fire extinguishers unless they need to use them. According to some technical experts, fire extinguishers are compressed gas at high pressure, need to be stored in cool conditions. Suitable temperatures to store the extinguishers are from -10 degrees Celsius to +50 degrees Celsius.
However, in the summer, when parking under the sun of more than 40 degrees Celsius, the temperature inside the car can reach up to 60 degrees Celsius. In particular, the dashboard on the car is made of plastic or leather, located under the front windshield, which will directly absorb heat from the sun, so the temperature in this area is often around 70 - 80 degrees Celsius, much higher than the threshold that fire extinguishers can withstand.
The temperature increases, causing the volume of the liquid inside to increase and reach a high enough pressure level, causing an explosion, which is extremely dangerous.
6. No regular maintenance

This is the best way to control the safety of the vehicle. Improper maintenance or use of substandard spare parts can also lead to electrical short circuits. Vehicle users should have the habit of regular vehicle care and maintenance. This also helps the vehicle owner detect early risks that can cause fire or explosion from the electrical system as well as easily control the situation of fuel leakage.
Additionally, regular car washing will remove dirt and grime that has built up on the car. These foreign elements can also cause localized damage.
