These symptoms of the car are "calling for help" from you, hurry up Tight maintenance

1. Abnormal idling when starting. Abnormal idling noise will occur when starting the car, which mostly occurs in cold weather. Many car owners will mistakenly think that the engine temperature is low, and the signal of the engine water temperature sensor is also greatly reduced, resulting in an increase in fuel injection, resulting in abnormal idling noise.

2. Generally speaking, the abnormal sound of the chassis is likely to be caused by the ternary catalyst. In addition to minor problems, the aluminum trioxide in the ternary catalyst accumulates carbon, accumulating too much afterta.It is easy to clump and fall off, and the lumpy carbon will make a noise if it cannot be discharged. Such problems are easy to cause the car to break down.

3. If these 4 phenomena occur in the car, it is very likely to break down! Old driver: Don't be careless to overhaul as soon as possible. The first phenomenon is oil leakage and oil burning. Many faults of cars are very intuitive. When the vehicle leaks oil or burns oil, we can directly detect abnormalities with the naked eye.

cars have these symptoms, don't panic, don't

1. In fact, sometimes these symptoms in cars don't need to be repaired. Next, I will explain to you. There is no need to repair any symptoms of the car. Cold start has the smell of gasoline. When the weather is hot, the time we take to start the car is also shortened.

2. The car exhaust pipe is smoking. Many car owners are very scared when they see the car exhaust pipe smoking and worry that the car will explode. In fact, the reason why the car exhaust pipe smokes is that gasoline contains water. Because the engine is too cold, the fuel does not burn completely when it enters the cylinder, and white smoke will be produced after the formation of water vapor.

3. Don't be fooled by the 4S store when you don't need to repair it in three situations. The brake disc is rusty. When the novice car owner encounters the situation that the brake disc is rusty, the first reaction is often that the brake disc needs to be replaced. Even if the car is sent to the 4S store, the people in the store will only say that if the brake disc is rusty, it must be replaced immediately.

4. There is also some abnormal noise of the car that comes from around the glass, which is mainly because the adhesive strip around the glass is aging. It only needs to be replaced, and the cost of replacement is not too high.

5. If these four phenomena occur in the car, it is very likely to break down! Old driver: Don't be careless to overhaul as soon as possible. The first phenomenon is oil leakage and oil burning. Many faults of cars are very intuitive. When the vehicle leaks oil or burns oil, we can directly detect abnormalities with the naked eye.

6. Attention to the owner: Don't be careless about these 5 small problems in the car, which are likely to be a harbinger of a major failure. Tire bulge Car tires are very important for the driving safety of the car. After all, the tire is the only part of the car that directly touches the ground, and its condition will directly affect the driving of the car.

What are the symptoms of car explosion

The symptoms of car explosion are: engine vibration. The engine temperature is too high. The combustion of fuel is incomplete, and there is black smoke in the exhaust gas. The engine power decreases. The fuel consumption increases. During normal driving, the speed suddenly changed inexplicably. Explosive shock is explosive combustion, also known as sudden explosion and combustion.

[Pacific Automobile Network] The engine will make a knocking sound during an explosion.The sound of a slight and discontinuous explosion is quite crisp, which is a bit like the sound of knocking on the iron triangle. In the case of a serious and continuous explosion, the engine will make a sound, and the engine will also be obviously weak at this time.

After the vehicle's explosion occurs, the most obvious symptom is that the vehicle makes a crisp metal knocking sound during driving. If it is a slight explosion, the metal noise is irregular and discontinuous. If it is a serious explosion, it will make a continuous and strong metal knocking sound, accompanied by a decrease in engine power. Weak situation.

The symptoms of car explosion are about the following types. First, the vehicle engine makes abnormal noise. This kind of failure is mainly manifested as the engine knocking on the cylinder. In most cases, there is too much carbon accumulation inside the engine, or the fuel quality is too poor, which requires cleaning the internal carbon accumulation of the engine and adding a higher standard. The gasoline of the number.

The phenomenon of car explosion: irregular "banging", "clicking" and "dangdang" metal knocking sounds occur in the engine. The engine trembled. The engine temperature is too high. The combustion of fuel is incomplete, and there is black smoke in the exhaust gas. The engine power decreases. The fuel consumption increases.

What are the symptoms of a car cylinder burst

1. The signs of engine cylinder burst are: the engine body temperature is too high, and the external temperature is above 90°; driving is weak; there is a strange sound when the friction of the cylinder plug, and the higher the frequency of abnormal sound with the increase in speed. The engine cylinder burst is caused by excessive temperature, and the piston expands and is stuck in the cylinder, resulting in the scrapping of the engine.

2. There will be corresponding signs before the car bursts the cylinder, such as: the vehicle's power is getting weaker and weaker, there is an abnormal sound from the friction of the cylinder plug, and the body temperature of the car engine is too high.The power of the vehicle is getting weaker and weaker: no matter how you step on the accelerator, the car just doesn't go, which may be a problem with the fuel supply system and ignition system.

3. The phenomenon of a car's cylinder burst is to turn off the engine, leak oil, the engine has holes, and the engine is completely scrapped.

4. The noise of the engine is obviously louder. When the car bursts the cylinder, it will produce violent friction due to the overheating and expansion of the piston, which will cause the engine to make abnormal noise.

5. What is the main manifestation of the bursting cylinder of the car? The engine noise is significantly expanded. When the vehicle bursts the cylinder, the deformation of the piston rod will cause strong friction with the cylinder liner due to overheating deformation, which will cause abnormal noise from the engine; the engine vibration is becoming more and more significant, and it is also likely that the exhaust pipe will produce black smoke when it is more serious.
