What is a car failure and what are the causes of car failure?

Occasional malfunction, thank you Wang.

The battery is out of power and can't catch fire:

Cause of failure: Although many vehicles use batteries that are maintenance-free, it is often difficult to find out if there is a problem with the battery. When the battery voltage is insufficient during driving, the engine will not start.

There are usually two situations when the battery is out of power, the battery life is generally 2 to 3 years, and when the battery life expires, it will suddenly run out of power when it is stopped; There is also the fact that we listen to the radio for a long time, forget to turn off the headlights, and the alarm of the immobilizer for a long time, etc., which causes the battery to be out of power.

Solution: 1. Pulled and started by other vehicles.

2. Borrow the power supply of other vehicles to start.

3. Use downhill to start.

Low oil alarm light on:

Cause of failure: the red light of the oil pot is on, if it is not a sensor failure, it is generally the lack of engine oil, and continuing to drive in the absence of oil is likely to cause the piston to break the cylinder block, and the car will suddenly shut down, which is not only very dangerous, but also the next maintenance cost is also very high.

Parking inspection: 1. Some cars burn engine oil, and car owners should be very experienced and can add matching engine oil by themselves. In the open suburbs, there is no other vehicle to help, and you have to drive forward, and you can't buy engine oil nearby, you can temporarily go to some stalls to buy soybean oil or peanut oil temporarily, and you should change the oil immediately after driving to the repair shop, otherwise it will leave a lot of charcoal.

This is a last resort. If you have other vehicles, you can borrow oil from them.

2. If you accidentally bump into the fuel tank and cause oil leakage, and there is no maintenance location nearby, we can chew the gum and paste it on the oil leakage part of the fuel tank, because after the chewing gum dries, it can tightly block the dripping oil part, which plays a good role in emergency relief.

3. If the oil circuit is damaged due to impact, don't add engine oil, and ask for road assistance.

Brake light alarm on:

Cause of failure: If we encounter the brake warning light on during the long distance, it means that the brake fluid level is not enough, and the brake system may be leaking.

Special reminder: at this time do not continue to drive, must be added in time to buy brake oil, if due to environmental factors can not buy brake fluid, you can buy a high number of liquor temporarily replaced, will not affect the effect of brakes, but can not brake frequently, should be immediately driven to the repair shop after the emergency maintenance.

Before traveling, it is necessary to check whether the braking system is normal, including: the degree of wear and tear of the brake pads, and also pay attention to whether the booster oil is sufficient. Special attention should be paid to the dust jacket of the sub-cylinder of the brake system, because if this part is broken into the dust, it will cause the piston to fail, and then lead to the increase of the braking distance when the car is braking; If water enters this part, brake failure will occur due to water mixed with the brake fluid.

Therefore, whether the dust jacket enters water or dust, it must be comprehensively inspected and repaired to prevent the brake from failing for long-distance driving.

I hope the subject and netizens are grateful.

Automobile failure refers to the phenomenon that a system, assembly, component, or entire vehicle loses its prescribed function. The essence is that there is an abnormal change in the matching status of the car part or part.

What are the common car breakdowns?

The engine will not ignite.

As an engine, the main reason why it doesn't start is because there is a problem with the battery, because the engine depends on the battery for starting, and once the battery rusts or drips oil, the engine can easily fail to start.

Poor idle operation.

It may be that the idle speed is unstable, the engine is shaking, the idle speed is higher than the specified upper limit, the idle speed is lower than the specified lower limit, or the idle speed is not soft. These phenomena are related to faulty or poor operation of injectors, oxygen sensors, air flow sensors, exhaust gas recirculation valves, etc. , as well as poor connection between the control circuit and the vacuum line.

Car leaks. Leaks in automobiles include fuel leaks, oil leaks, coolant leaks, brake fluid leaks, steering oil leaks, lubricating oil leaks, and refrigerant leaks, as well as battery leaks and electrical system leaks. Car leaks can easily lead to overheating of the car and damage to the mechanism.

If the steering oil leaks, it is easy to cause steering failure; Brake fluid leakage can easily lead to brake failure, etc.

Automobile failure refers to the phenomenon of the loss of the prescribed function of the system, assembly and parts of the car or the whole body. In fact, the essence is that the car parts themselves or the coordination state between the parts have changed abnormally. Common Car Breakdowns:

Engine not ignition: The main reason for not igniting is the battery. Because the engine starts by the battery, and once the battery rusts or drips, it is easy to cause the engine to fail to ignite.

Poor idling: Unstable idling may cause engine shake; The idle speed is higher than the stated upper limit; The idle speed is below the specified lower limit; Or the idle speed is uneven. Car leaks.

Automobile leaks include fuel leakage, engine oil leakage, coolant leakage, brake fluid leakage, steering oil leakage, lubrication pin oil leakage, refrigerant leakage, etc. and battery fluid leaks and electrical system leaks. Car air leakage can easily cause car overheating and mechanism damage.

If the steering oil leaks, it is easy to cause the car to fail; Brake fluid leakage can easily lead to brake failure.
