What is the reason for the sudden car fire in summer?

The possible causes of automobile spontaneous combustion in summer are as follows:

1: the brake system is overheated.

The braking system of the vehicle stops the vehicle through friction, which will inevitably generate heat. In the case of high temperature in summer, the braking system will undergo a severe test. Long-term braking friction leads to a sharp rise in the temperature of tires and brake drums, and tire fire leads to spontaneous combustion of vehicles. This situation is also one of the most common causes of truck spontaneous combustion in summer.

2. spontaneous combustion of goods

Due to the temperature, some goods are prone to spontaneous combustion after being exposed to the sun. At this time, we should pay special attention to the types of goods to be transported. Vehicles transporting cotton, cloth and waste paper must wrap the goods firmly before the vehicles leave, which often happens because cigarette butts will ignite the goods. Some chemicals must be shielded and ventilated. It is particularly important to note that the weather changes rapidly in summer, and vehicles transporting calcium carbide must be waterproof, otherwise calcium carbide will burn violently when it meets water.

3. Circuit system failure

The circuit system is aging, and the exposed rubber grounding wire contacts with the live wire to generate sparks to ignite the plastic parts inside the car. This kind of spontaneous combustion case is common, which has become the most easily overlooked reason and the highest spontaneous combustion rate of freight cars in summer. Especially at present, there are more and more electronic devices in trucks, and many car owners like to modify their own audio and other electronic devices. These things will involve circuit changes, which will easily lead to fires if you are not careful.

4. Flammable articles in the cab are exposed to the sun.

Many truck drivers have the habit of smoking, but after lighting a cigarette, they habitually throw their lighters on the center console. After a long period of sun exposure, the temperature in the car can easily detonate the combustible gas in the lighter, causing a fire. Other perfumes placed on the center console also contain flammable chemicals, which can easily become a time bomb for truck spontaneous combustion in summer.

5: Smoking

Many people think that smoking in trucks is the most normal thing, but few people regard it as the cause of spontaneous combustion of trucks, but in fact it is also the most easily overlooked point. Uninterrupted cigarette butts are an absolute safety hazard in the cab.

Measures to prevent spontaneous combustion:

1: Check tires and brake drums frequently to prevent overheating. Vehicles with water spray devices should always pay attention to cooling the braking system.

2. Do a good job in daily maintenance inspection. Many car owners have a maintenance misunderstanding, thinking that replacing the three filters means doing regular maintenance. In fact, regular maintenance also includes the inspection of braking system, steering system, oil circuit and electrical circuit, especially in summer, it is necessary to develop the habit of regular maintenance of vehicles.

3. Equipped with an effective fire extinguisher. The vehicle is equipped with a fire extinguisher. Generally speaking, a fire extinguishing device of about 2 kg can play the role of emergency fire extinguishing. The key is to learn to use it, and pay attention to check whether it exceeds the service life. If it expires, it should be replaced immediately. In case of fire while driving, you should call the police as soon as possible, and use vehicle-mounted fire extinguishers or other fire extinguishing conditions for initial fighting.

4: Don't put flammable items under the light. Gas lighter, air freshener, perfume, etc. Should not be placed in the parts of the car that are easily exposed to sunlight, such as the dashboard; Don't put dangerous oil products such as gasoline and diesel in the car.

5: Don't modify the car easily. If modification is needed, professional technicians should do it professionally. For example, when modifying the circuit or adding equipment, the power cord must be wrapped to prevent leakage.
