It is good to have these fake faults in vehicles without repairing the exhaust pipe leaking.
Some car owners love their car. As long as the car is out of order, it rushes to the 4S shop to repair it. However, in fact, some minor problems are not so-called "failures", and they do not need to spend money in 4S stores. Today, we give everyone a chance to popularize what is the "fake fault" of a car. Everyone may pay more attention when using a car.
◠After the flameout of the exhaust pipe, there is a noise. After the vehicle shuts off, it will hear a metal-like “baba†sound from the exhaust pipe. Is this normal?
After the car exhaust pipe is heated, the metal will expand, and after extinguishing the fire, the muffler in the exhaust pipe will have a phenomenon of thermal expansion and contraction. Therefore, the sound that everyone hears is actually the sound produced by the contraction of metal in the exhaust pipe. This is a normal phenomenon.
â— When the exhaust pipe leaks out of the water and you don't understand the car, when you see a lot of car exhaust pipe dripping phenomenon, I really think it is a car failure.
In fact, it is a good thing for the exhaust pipe to drip. After the gasoline in the vehicle is completely combusted, it will produce carbon dioxide and water. Under high temperature conditions, the water will turn into water vapor. During the discharge process, it will continue to condense into small droplets after passing through the three-way catalyst, muffler and exhaust pipe. The more naturally comes out with the exhaust pipe.
â— If the battery has electricity but the car cannot start, the engine cannot start. Check it and see if the battery has electricity. Nothing else will be a problem. Why can't the car start? This is definitely a car breakdown.
The truth may be that the gear is hung in D and there is no reason to push back the P gear. When the vehicle is just starting up, the power transmission is very strong. If the gear is hung on the D block named driving gear at this time, the momentary impact will bring great security risks. Therefore, when the car manufacturer designs, only when the gear is allowed to be in the P range and the N range, the vehicle can be started.
â— If you hang the D block, the body will shake and operate the automatic transmission. After hanging the D block, the body will shake once. Is this a problem with the transmission?
Under the action of the torque converter, the automatic gearbox engages the one-piece friction plate to generate a forward driving force. At this time, the depressing brake pedal prevents this forward force, thus causing slight body shake.
â— New car brake disc rust I bought a new car, how are the brakes rusted? This car should not be a refurbished car? In fact, this is also a normal situation, especially for some of the stock cars, brake disk rust is more obvious.
This is mainly because the brake discs are usually made of steel (usually cast steel). A long period of time will naturally result in a rust layer on the brake disc. This situation does not have to worry about, as long as the normal driving, running up and running for some time, the rust will be slowly gone.
â— The rear door of the vehicle can't be opened from the inside and is sitting in the back row. After parking, it cannot open the door, but it can be easily opened outside the vehicle. Why?
It may be that the passenger or the driver of the vehicle activates the child safety lock by simply opening the door from the outside and moving the handle of the child lock to the open position. Many children nowadays have children's locks in the back row, mainly to prevent children from opening the door while the vehicle is in motion.
â— After the car is locked, the headlights are still on. The headlights are still on. This is not a light.
In fact, this is a headlight delay shutdown function, and many models on the market today are equipped with this function. The purpose is to provide external lighting for a period of time after the owner gets off. With such an intimate intention, everyone should not misunderstand it.
â— After the car is locked, the front and rear lights are on and the car lights are on. Why?
This is called a parking light. Parking lights are turned on in places where visibility is low. This is a warning to passing vehicles. In many European countries, there are relevant laws governing the opening of parking lights.
â— When the steering wheel is not listening, many people have said that during the driving process, sometimes the steering wheel feels that it does not listen to the call, and it forces itself in the opposite direction. Is this a problem with the steering wheel?
This is the effect of the lane departure warning system. When the lane is deviated, this configuration will send an alarm signal so that the driver can react and adjust.
â— Headlamp cleaning sometimes can not open the car and ultimately the lights, just as people can not be the same as the eyes. The headlight cleaning function is designed to prevent headlight illumination from being reduced due to dust and dirt. Some car owners reported that the headlight cleaning function can sometimes not be turned on, is it not broken.
This may be because everyone did not turn on headlight lighting when using the headlight cleaning function. This function can only be used when the headlights are turned on.
â— When the car is started, the smell of gasoline is rather heavy. The most unpleasant thing is that after the vehicle starts up, it will smell heavy gasoline. Is this an oil leak? Is there any problem?
Don't worry, this is a more normal situation. The main reason is that after the cold start of the vehicle, the temperature of the engine is not enough, and gasoline cannot be completely burned, so it smells of gasoline. Once the engine temperature reaches the normal operating temperature, it is OK.
