Some car owners love car heartpocked，Love the car and run in the 4S shop with a little bit of energy，A little vowed to kill the failure at the momentum of the fault，Of course, this mentality is good，Driving safety is to rely on this careful and serious。but but，Some seemingly faulty problems，Not a failure at all，When you run to the 4S shop, you can only let it be slaughtered。So which are false faults?

Drops of water dripping after normal driving, I believe many owners have encountered，Seeing this situation, the owners can't help but a little panic，Worried about whether it has added gasoline with exceeding the standard，That is both fuel consumption and damage to the car。This is a worry -free，The phenomenon of dripping water in the exhaust pipe is not a fault，Instead, it is a normal good phenomenon，Because the gasoline burning during driving is very sufficient，The gasoline after completely burning will generate water and carbon dioxide，After the driving is over，Water vapor will be condensed into water drops after the exhaust pipe，Drop it down along the exhaust pipe，So this situation is not to worry about。

Car with a manual gearbox，I believe many friends have encountered this situation，Sometimes it can be hung up after stepping on the clutch，Sometimes it is easy to hang。Sometimes it can be hung in a little force，But it will be accompanied by a sound of "咣"。Don't worry，This is a normal phenomenon! Because generally manual transmission reversing is not equipped with a synchronizer with a forward gear，and the front of the inverted gear is not a cone。This leads to，Garrier hangs into the inverted teeth "Pure luck"。Good luck，The teeth of the gear and the inverted teeth are in one position，It is easy to hang。Tips，You can hang it in force，But there will be no sound，Alternately，Can't hang in。Encountered a situation where you can't hang in，It is recommended to hang Seabetin the forward gear first，Then step on the clutch，Hanging reverse gear，Never worry，Solution with "violence"。

Some cars，When lifting the lift to look up to see the chassis，You can see somewhere on the body guard，There is an obvious "oil trace"。Actually that's not oil，but when the car leaves the factory，A layer of protective wax coated at the bottom of the body。When using the car,，These wax，Heating melted，A "oil trace" that is not easy to dry encountered this situation，No need to control，No need to spend the time to get rid of those melted waxes，No effect!

Drive manual transmission car，I believe most friends have encountered this situation，When the vehicle needs to be reversed and hangs into the barrier, step on the clutch but cannot hang in，But there are no difficulties in hung in many times.，Sometimes you only need to work slightly to "hang in。Because the general manual transmission reverse gear is not equipped with a synchronizer owned by the forward gear，and the front end of the inverted teeth is not a cone，This will cause a feeling of touching the air when the transition from the forward gear to the reverse gear，The timing of the stop gear is correct，The teeth of the gear and the inverted gear will be quite smooth when at the same position。

Whether it is a high -end car. Low -grade cars. Imported cars. Domestic cars. New cars. Old cars have different degrees of noise problems。The noise in the car mainly comes from five aspects of engine noise. Wind noise.。Vehicle driving，The engine runs at high speed，Its noise is introduced into the car through the firewall. The bottom wall, etc. are introduced into the car; the body resonance generated by the car on the bumpy road，or the windows opened when driving at high speeds cannot produce resonance will become noise。Due to narrow space in the car，Noise cannot be effectively absorbed，Mutual impacts sometimes resonate in the car。Driving，The noise generated by the suspension system of the car and the noise generated by the tire will be introduced into the car through the seabet iochassis。Different suspension methods. Tire brands are different. Different tire patterns. The noise generated by different tire pressures is also different; the shape of the body is different and the driving speed is different，The wind noise produced by it is also different。Under normal circumstances，The higher the driving speed，The greater the wind noise。

Another friends are after the vehicle is over after the vehicle is over，I will vaguely hear the regular "daemon" sound of the exhaust pipe office of the rear of the car，This also really frightened a group of people，Actually，​​This is because the engine is at work，The emissions of the tail gas will be transmitted to the exhaust pipe，The exhaust pipe is heated and expanded，After the fire is turned off，Decrease temperature，The exhaust pipe metal will shrink，So sounding，Pure physical phenomenon，Not a problem hidden danger。

Someone asked again，Sometimes I have no driving，Just stop the car alone for a long time，Why does it have a pile of water in the ground location of its stay，This is not the water of the exhaust pipe, right?，Is this a problem? The riders who are worried about this problem also put their hearts in their stomachs，This situation generally occurs in summer，If you look closely at the water under the car, you will find that the stagnant water is clean and transparent，Is it similar to the dripping water from the daily home? Yes，This is when the vehicle turns on the air conditioner，Because the surface temperature of the air conditioner evaporator is very low，So the hot air in the car will be condensed on the surface of the evaporator and forms a water drop，Disparted through the pipeline to under the car，That's that simple。

This is because gasoline contains moisture，and the engine is too cold，At this time, the fuel that entered the cylinder was not completely burned and caused a white smoke or water vapor to form a white smoke。Winter or rainy season When the Seabetcar is launched for the first time，Frequent white smoke。This is not tight，Once the engine temperature rises，White smoke will disappear。This situation does not need to be maintained。

I believe that many car owners have been deceived by the "false failure" of the car away.，In fact, a little bit of a little bit of understanding of the car condition and related car knowledge，You can make a preliminary judgment on the problem that your car loves occurred seriously，Save money and energy and time，It really gets extra!
