How to prevent spontaneous combustion of cars?

Precursor to spontaneous combustion
1. Excessive fouling of the engine;
2. Sudden difficulties in starting the car or significant increase in shaking during driving;
3. The fuel consumption of the car is suddenly increasing than usual, and there is no other reason.
4. Spontaneous combustion of automobiles generally has precursors, such as black smoke, scorched smell and so on.

Cause
1, is the car’s oil circuit problems, resulting in oil leakage, leakage.
2. It is the aging of the vehicle wire or improper connection that causes a short circuit or a spark.
3, is due to high temperature caused by the combustion of flammable materials.
4. It is due to vehicle impact, or machine failure caused by fire.
5. The engine sludge accumulates too much, and the high temperature in summer plus the high temperature of the engine causes the sludge to spontaneously combust due to the high temperature.

Precautionary principle
1, do not easily modify the car without permission.
2, regularly check the circuit oil circuit: because the line of the car after three or four years of use, there will often be aging rubber, the wire resistance increases and heat up, prone to short circuits, such as battery terminal posts due to impurities, oil or corrosion to make the contact loose and heating, ignition of the wire insulation layer; long-term vibration or temperature changes affected by the line contact loosening.
3, do not put a lighter on the dashboard: gas lighters, fresheners, mosquito repellents and other easy to be heated and expanded after the explosion caused fire.
4. Equipped with fire extinguishers and car fire blankets.
5. Clean up the engine sludge before the summer comes.

First aid program
In the narrow space where the car is concentrated, various flammable and explosive materials such as lines and gasoline are intertwined with each other, and once it catches fire, the car may burn in just a few minutes. So how can we quickly implement self-help in the first time and reduce the degree of loss of the car?
1. when the car is on the way, the driver suddenly finds that there is a flame or black smoke coming out of the front part of the car, he should immediately pull over and then turn off the engine, because turning off the power can quickly disconnect the oil pump and reduce gasoline combustion.
2. the driver should quickly leave the burning car compartment after turning off the power.
3., after leaving the carriage, the driver should immediately take the fire extinguisher to check the fire. When checking the fire, do not rush to open the front cover of the car, but should first open the front cover of the small slit, wait for oxygen to enter for a while, and then slowly open all of it, with a fire extinguisher for fire fighting. Because once the lid is opened violently, oxygen will quickly enter, and the flame of the car will suddenly become larger, easily burning itself.
4.when fighting with a fire extinguisher, should cool down the quasi-fuel tank and the burning part to extinguish the fire and avoid explosion. At the same time, call the fire alarm for help.
