The reasons why a car suddenly fails to start are: 1. Battery depletion: The characteristic manifestation is that the starter begins to turn but the rotation speed is insufficient, and later the starter only makes a clicking sound without turning. Low temperatures in winter and forgetting to turn off certain electrical equipment can cause the vehicle to fail to start; 2. Gasoline flow obstruction: The characteristic manifestation is that there is no oil pressure in the engine fuel supply pipe. This situation often occurs on cold mornings and is caused by long-term dirt accumulation in the fuel pipeline; 3. Poor working condition of the ignition system: The characteristic manifestation is that in cold weather, due to low intake air temperature, the fuel does not atomize well in the cylinder. If combined with insufficient ignition energy, the result will be cylinder flooding, where excessive fuel accumulates in the cylinder, exceeding the ignition limit concentration.

Does Car Insurance Cover Flood Damage to Vehicles?

Comprehensive vehicle damage insurance is required to receive full compensation. For engine damage caused by driving through floodwaters, if the vehicle is insured with a water-related damage rider, the engine repairs fall within the coverage scope. Without this specific rider, insurers only cover cleaning costs for water ingress, excluding engine repair expenses. Below are extended details about auto insurance coverage: 1. Comprehensive vehicle damage insurance serves as the primary coverage, with water-related damage as a supplementary rider: Officially termed "Engine Damage Due to Water Ingress Coverage," this rider compensates for engine damage resulting from improper operation when driving through flooded roads or submersion, provided the vehicle carries comprehensive coverage as prerequisite. 2. Article 4 of China's "Household Vehicle Damage Insurance Clauses" stipulates: During the insurance period, the insurer shall compensate for vehicle damage caused by the following circumstances when operated by the policyholder or authorized drivers: (1) Collision, overturning, or falling. (2) Fire, explosion, or spontaneous combustion. (3) Falling or collapsing external objects.

Where is the side airbag installed?

The side airbag is installed on the outer side of the seat, primarily designed to reduce injuries caused by side impacts. The working principle of car airbags is as follows: the sensor system continuously sends speed change information to the control unit, which analyzes and evaluates this data. The car airbag consists of an inflation sensor and an inflation system. Its functions include: protecting occupants by reducing contact with interior objects, more evenly distributing the impact force on the head and chest, absorbing the kinetic energy of the occupants, thereby supplementing the effectiveness of seat belts. Precautions for using airbags include: 1. Airbags must be used in conjunction with seat belts; 2. Maintain an appropriate distance from the airbag while seated; 3. Do not place objects in front of, above, or near the airbag; 4. Maintain good driving habits to ensure a certain distance between the chest and the steering wheel.
